Managing documents used to be a simple problem — a filing cabinet, a label, and a person who knew where everything lived. Today, that world no longer exists. Modern businesses generate thousands of documents every week: scanned invoices, onboarding forms, contracts, compliance reports, shipping manifests, insurance claims, HR files, purchase orders, project documents, and more. Each one contains critical information, but they arrive from different sources, in different formats, and often as scanned PDFs or smartphone photos.
As organizations scale, this creates a massive operational burden. Teams spend hours searching for files, retyping information, correcting errors, or hunting down missing paperwork. The cost of this inefficiency becomes clear:
Workflows slow down because teams can’t find the right documents
Compliance risks increase when information is misplaced
Operational insights get buried in unstructured PDFs
Manual data entry drains time and increases error rates
This is why more companies are turning to OCR-powered document management software — systems that not only store documents but also understand them. OCR (Optical Character Recognition) converts scanned documents into searchable, usable data, transforming a folder full of PDFs into a structured, queryable knowledge layer.
However, traditional OCR is no longer enough. Businesses now handle multilingual documents, low-quality scans, handwritten forms, and complex layouts like tables, form fields, checkboxes, and spreadsheets. This shift demands OCR engines that are fast, accurate, layout-aware, AI-friendly, and easy to integrate into modern document workflows.
This is where LLMWhisperer and Unstract enter the picture. LLMWhisperer acts as the next-generation OCR/document parsing engine — capable of handling all major formats while preserving layout, understanding checkboxes, reading handwriting, and extracting data with high fidelity. Unstract completes the workflow by applying LLMs to the extracted text, enabling enterprise-grade document classification, splitting, parsing, and data automation.
Together, they redefine what businesses expect from OCR in document management — not just text extraction, but intelligent, scalable, automation-ready data processing.
What is Document Management?
Document management is the discipline of capturing, storing, organizing, and retrieving documents in a secure, searchable, and compliant way. Modern organizations rely on a Document Management System (DMS) to ensure that documents — whether digital or scanned — are always available to the right people at the right time.
A robust DMS typically includes:
Document capture (upload, scan, import from emails, cloud drives, APIs)
Historically, document management was manual. Paper files lived in cabinets. “Search” meant asking someone in the office who remembered where a document might be. Classification relied on colored folders. Retrieval required physically walking to storage rooms.
As businesses digitized, these systems evolved into electronic DMS solutions, allowing teams to upload PDFs instead of filing paper. But digitization alone created a new problem: digital clutter. If a company uploads 10,000 PDFs to a shared drive without structure, it becomes as chaotic as the paper era.
That is why the industry shifted to intelligent document management, where the system not only stores PDFs but also extracts and understands the content inside them — using OCR, AI, and automation.
Real-World Examples of Document Management in Action
HR Departments
Store employee contracts, onboarding forms, ID documents, performance reviews
OCR enables quick search: “Show me all employees with contract renewal in 2024”
Finance & Accounts Payable
Automate invoice capture, extract vendor name, amount, due date
Reduce manual entry and eliminate human errors
Legal & Compliance Teams
Manage contracts, agreements, regulatory filings
Ensure versions are tracked and documents are audit-ready
Insurance & Banking
Process scanned claims, KYC forms, policy documents
Classify and extract data automatically using OCR document management tools
Operations & Logistics
Manage bills of lading, shipping manifests, delivery receipts
Use OCR to extract shipment details instantly
Without a modern DMS — especially one enhanced by OCR — companies lose visibility into their most critical information. With it, they gain speed, efficiency, compliance, and the ability to automate previously manual processes.
Why Document Management Is Important in Business
Modern businesses run on information. Contracts, invoices, HR files, compliance documents, vendor agreements, tax records, customer files, policy papers—every department depends on accurate and timely access to documents. Without a proper document management system (DMS), even a fast-growing company can collapse under the weight of its own paperwork.
A strong document management strategy is no longer optional—it is foundational. Here’s why:
1. Centralized Storage, Version Control, and Audit Trails
When documents are scattered across emails, desktops, shared drives, and paper folders, confusion becomes inevitable. A DMS creates a single source of truth, ensuring that:
Every document has one authoritative version
Teams always know who uploaded, edited, or approved a file
Old versions are archived, not lost
Decision-makers work with the correct data, every time
In industries like legal, finance, insurance, and healthcare, version control and audit logs are not just helpful—they are legally required. A DMS automatically maintains audit trails, tracking every change for compliance and transparency.
2. Compliance and Data Governance
Regulatory frameworks such as GDPR, SOC 2, HIPAA, and ISO standards demand strict control over document access, retention, and privacy. Without automation:
Sensitive documents may be overexposed
Retention periods may be missed
Unauthorized edits may go unnoticed
Compliance audits become painful and expensive
A robust DMS enforces access permissions, retention rules, encryption, and role-based controls—ensuring compliance without relying on manual policing.
3. Improved Accessibility, Collaboration, and Decision-Making
Remote teams, distributed offices, and digital workflows need instant access to documents. A modern DMS enables:
Full-text search to find documents instantly
Cloud access for remote collaboration
Automated routing and approvals
Faster decision-making backed by accurate information
When documents are accessible and searchable, teams spend less time hunting for files and more time acting on insights. This accelerates everything—from approving invoices to onboarding employees to negotiating contracts.
Role of OCR in Document Management Systems
Traditional document management systems focus on storage. Modern systems focus on understanding documents — and that leap is powered by OCR (Optical Character Recognition).
OCR transforms unstructured content—scanned PDFs, images, faxed forms, photographed documents—into searchable, machine-readable text. In other words, OCR is what turns a folder full of scanned paperwork into a structured knowledge base.
1. What OCR Means Inside a Document Management System
In a DMS, OCR performs three major functions:
Text Extraction Converts images and scanned PDFs into digital text.
Content Indexing Enables full-text search, filtering, and intelligent retrieval.
Data Structuring Supports automatic extraction of fields, tables, labels, checkboxes, and handwritten notes.
This is why modern solutions are often referred to as OCR document management systems—because OCR is now the engine that powers intelligent document workflows.
2. How OCR Document Management Systems Automate Data Extraction
A DMS equipped with OCR does much more than store files. It automates critical workflows:
Extracting key fields (names, dates, amounts) from invoices, forms, contracts
Reading tables in financial or operational documents
Capturing handwritten notes in applications or inspection reports
Recognizing checkbox states in forms
Auto-tagging documents with metadata like document type, category, or department
This automation allows businesses to eliminate manual data entry—one of the biggest sources of delays and human error.
3. Benefits of OCR in Document Management
Here are the real-world advantages organizations gain by using OCR:
Speed
Data that once took days to extract can now be processed in seconds.
Searchability
With OCR, even scanned documents become fully searchable. You can instantly search for:
These tags fuel intelligent routing, approvals, and analytics.
Reduced Human Error
Manual data entry is slow and prone to mistakes. OCR eliminates typos, copy-paste issues, and inconsistent labeling.
Better Decision-Making
When documents become structured data, organizations gain insights into:
Cash flow
Contract risks
Vendor performance
Compliance exposure
Operational bottlenecks
OCR turns document chaos into a structured, searchable, business-ready dataset.
Why Accurate OCR Is Vital
In document-driven industries, the value of OCR isn’t simply about “reading text.” It’s about reading correct text. A single misread digit, checkbox, or date can ripple across compliance workflows, billing systems, customer communication, and automated decision engines.
This is why accuracy—especially in ocr document management systems—is non-negotiable.
1. How OCR Errors Impact Compliance, Billing, and Automation
Even minor extraction errors can create major downstream consequences:
Compliance failures Misreading a policy number, contract clause, or expiration date can trigger audit issues, penalties, or legal exposure.
Billing discrepancies A misplaced decimal in an invoice amount or tax figure can lead to overbilling, underbilling, or reconciliation delays.
Broken automation flows Automated document routing and approval systems depend on correct fields. If OCR mislabels “Vendor Name” or misreads an “Invoice Due Date,” the workflow fails silently.
Customer dissatisfaction Incorrect extraction in claims, applications, or customer forms results in longer turnaround times and repeated document submissions.
Accurate OCR isn’t just about convenience—it directly influences operational reliability and financial accuracy.
Modern organizations deal with documents in every possible condition:
Low-resolution scans from offices or mobile apps
Handwritten notes, signatures, and free-text fields
Multilingual content and mixed-script PDFs
Documents with noise, shadows, stains, folds, or aging artifacts
Forms with checkboxes, radio buttons, and micro-labels
Traditional OCR engines often fail here—especially with handwriting or multilingual content. This is where next-generation tools like LLMWhisperer excel, offering high accuracy even on low-quality inputs.
3. Importance of Layout Preservation and Data Normalization
Accuracy is not only about text—it’s also about structure.
Document management workflows rely heavily on layout fidelity:
Tables must maintain rows and columns
Headings must map to the right fields
Checkboxes must be extracted as clear booleans
Numeric data should maintain decimals, symbols, and currency
Dates must be preserved or normalized into standard formats
Without layout preservation, document automation collapses. With it, OCR results become clean, structured, and ready for downstream AI or rule-based processing.
Selecting the Right OCR for Document Management
Choosing the right ocr document management software can make or break your automation strategy. The ideal OCR engine must balance speed, accuracy, flexibility, and developer-friendliness—all while fitting seamlessly into your existing DMS stack.
Here are the key considerations.
1. Evaluation Criteria for Modern OCR Engines
When comparing document management OCR tools, organizations typically assess:
Speed
The engine must process thousands of pages efficiently, especially in bulk ingestion scenarios.
Accuracy
Core for structured documents (invoices, forms) and unstructured documents (contracts, letters). Accuracy includes handwriting recognition, table fidelity, checkbox detection, and multilingual support.
Supported Formats
A strong OCR engine should handle:
PDFs (native + scanned)
Images (JPG, PNG, TIFF, WebP)
Office files (DOCX, XLSX, PPTX)
Form-heavy PDFs
Mixed-content pages
This is critical for enterprise DMS pipelines where documents come from diverse sources.
Multilingual Capability
Global organizations demand OCR that can parse 100+ languages—including dialects, accented text, and mixed-language content.
Integration Flexibility
Systems should provide:
REST APIs
SDKs or client libraries
Webhooks
On-premise deployment options
This ensures compatibility with platforms like SharePoint, Alfresco, OpenText, Box, OneDrive, or custom DMS solutions.
2. Cloud vs. On-Premise OCR for Document Management
Cloud OCR
Easy to deploy
Low infrastructure overhead
Perfect for general files and distributed teams
On-Premise OCR
Required in regulated industries (finance, healthcare, insurance)
Ensures complete data security and sovereignty
Enables processing sensitive documents fully within private infrastructure
LLMWhisperer uniquely offers both models — cloud-based simplicity and secure on-premise deployment.
3. Why Enterprises Prefer AI-Augmented OCR Engines Like LLMWhisperer
Legacy OCR engines rely solely on pattern recognition. Modern document ecosystems require much more:
Layout preservation for tables, forms, and contracts
Handwriting recognition
Checkbox/radio button detection
Low-fidelity document enhancement
Spatial mapping through bounding boxes
Support for high-entropy or multi-format documents
LLMWhisperer delivers all this—while staying AI-friendly, meaning it prepares perfect input for downstream LLMs in document management workflows.
This combination of:
High accuracy
Multi-format support
Enterprise-grade integration
On-premise availability
Layout-preserving output
is exactly why organizations now choose LLMWhisperer as their primary OCR for document management.
What is LLMWhisperer?
LLMWhisperer is Unstract’s high-precision OCR and text-parsing engine designed specifically for structured document understanding. Unlike traditional OCR tools that simply read characters from a PDF or image, LLMWhisperer focuses on preserving the structure, layout, and semantics of a document so that downstream automation systems — including LLMs — can interpret the content accurately.
Not an LLM — but the ideal preprocessing layer for LLMs
A key distinction is that LLMWhisperer is not a large language model. It does not generate or infer meaning. Instead, its job is to:
Extract raw text with exceptional accuracy
Preserve layout, indentation, tables, checkboxes, and spatial regions
Clean and normalize messy scans, photos, and multi-format files
Output AI-ready text that LLMs can reason over without confusion
Think of LLMWhisperer as the bridge between messy real-world documents and intelligent AI processing:
LLMs understand relationships → clean, structured data
This makes it indispensable for modern document management systems where PDFs, TIFF scans, Excel sheets, and photographed documents all flow into a central automation pipeline.
The Bridge Between Raw Text and Intelligent Parsing
LLMWhisperer solves the biggest failure point in legacy OCR workflows: OCR extracts text, but AI needs structure.
For example:
Invoices have columns
Claims forms have checkboxes
Contracts have indentation and clause hierarchy
Financial statements have multi-row, multi-sheet tables
If OCR destroys the structure, downstream extraction breaks. LLMWhisperer preserves:
Column alignment
Table structures
Visual markers
Line numbers
Bounding boxes
Checkmark states
Mixed-language text
It guarantees that the output is not just text — but organized text, ready for any AI, rule-based, or workflow engine.
Why LLMWhisperer Is the Best OCR for Document Management
Modern document management systems (DMS) require more than scanned-PDF OCR. They need a robust engine that can handle:
Millions of documents
Multiple formats (PDF, images, Word, Excel, CSV)
Noisy scans and mobile captures
Complex financial tables
Forms, checkboxes, radio buttons
Multilingual text
LLMWhisperer was built for exactly this environment.
1. Scalability at Enterprise Level
Businesses managing HR archives, insurance forms, legal files, or financial documents must process high volumes without failures. LLMWhisperer delivers:
High-throughput processing
Stable performance across thousands of pages
Auto-repair of problematic PDFs
Intelligent fallback modes for low-quality inputs
Whether processing a handful of documents or an entire archive, it remains fast, predictable, and accurate.
2. Industry-Leading Layout Accuracy
OCR accuracy means nothing if the structure collapses. LLMWhisperer’s layout-preserving output ensures:
Tables maintain row/column alignment
Multi-level lists and clauses retain indentation
Tables from Excel remain parseable
Forms keep checkbox states
Even complex insurance, banking, and healthcare PDFs remain intact
This level of fidelity makes it ideal for any document management OCR workflow where structure → meaning.
3. Exceptional Low-Fidelity Tolerance
Real-world documents are rarely perfect.
Shadows
Folds
Skewed camera angles
Faint handwriting
Mixed fonts
Watermarks
LLMWhisperer’s preprocessing engine applies:
De-skewing
Denoising
Auto-contrast
Median/Gaussian filtering
AI-enhanced image correction
Even documents considered “unusable” by traditional OCR engines become readable and well-structured.

How LLMWhisperer Supports Document Management
Document Ingestion: API & Cloud Connectors
A document management system is only as strong as its ingestion layer. LLMWhisperer integrates seamlessly into Unstract’s connector ecosystem, allowing businesses to move documents from any storage environment into their OCR pipeline without friction.
Unstract supports ingestion from a wide range of data sources—cloud storage, file servers, object stores, and databases. Documents can be fed into LLMWhisperer in two primary ways:
1. Ingestion via Connectors (Cloud & File Systems)
Unstract’s connector framework allows organizations to plug in their existing storage systems directly into a workflow. This enables automated ingestion of large document volumes—rent agreements, contracts, invoices, claims, HR files, policy forms, and more.
How ingestion works:
Navigate to Settings → Connectors, or add a connector while building a workflow.
Choose a connector type (e.g., AWS S3, Azure Blob, Google Drive, Salesforce, SFTP, PostgreSQL, etc.).
Provide the authentication details (bucket names, access keys, database URLs, credentials).
Test Connection to validate access.
Save and attach the connector as the Source for your workflow.
When the workflow runs, documents from the connector automatically flow into LLMWhisperer for OCR processing.
Why this matters for document management: Businesses no longer need to manually upload files or export data. A connector-enabled workflow ingests documents continuously and reliably, making LLMWhisperer a scalable backbone for enterprise document automation.

Once documents enter the system through API or connectors, LLMWhisperer handles the second stage of document management—parsing. This is where raw files (PDFs, scans, images, Excel sheets) are transformed into structured and layout-aware text ready for downstream AI processing.
How parsing works:
LLMWhisperer identifies the document type (scanned, native, Excel, form, table-heavy, handwritten).
It selects the appropriate OCR mode (native, low-cost, high-quality, form, or table).
The engine performs OCR, layout analysis, handwriting extraction, and structure reconstruction.
Output is returned in a clean, consistent format—preserving indentation, columns, tables, checkboxes, and line order.
This parsed output becomes the foundation for deeper intelligence tasks such as:
Classification
Entity extraction
Policy data mapping
Contract clause detection
Claims processing automation
Why this parsing layer is crucial: OCR isn’t just about reading characters. In document management, the structure is as important as the text. LLMWhisperer’s ability to preserve layout (columns, tables, checkboxes, field alignment) ensures that AI/LLM models receive data in a format they can accurately interpret—leading to higher accuracy in automated workflows.
Combined with Unstract’s processing tools, LLMWhisperer becomes a core component of enterprise document automation, enabling organizations to move from raw, unstructured files to validated, searchable, and fully structured data — all while minimizing manual effort.
What is Unstract? The AI/LLM Layer for Document Understanding
Modern enterprises deal with thousands of unstructured documents every day—contracts, invoices, claims, forms, reports, and handwritten submissions. Traditional IDP and RPA tools struggle with long, complex, multi-page documents because they lack semantic understanding.
Unstract solves this problem.
Unstract is an open-source, no-code platform built specifically for automating complex business processes involving unstructured documents—powered by Large Language Models (LLMs) and Human-in-the-Loop (HITL) capabilities. Instead of relying only on template-based OCR, Unstract adds an intelligent interpretation layer that understands meaning, relationships, and context inside documents.
Where OCR (like LLMWhisperer) extracts text and structure, Unstract extracts understanding.
How Unstract Uses LLMs to Extract Meaning from OCR Outputs
Once LLMWhisperer converts PDFs, images, scans, and spreadsheets into clean, layout-preserving text, Unstract takes over:
1. LLMs interpret the extracted text
LLMs analyze the OCR output, detect entities, relationships, classifications, intent, and numerical meaning. Examples:
Identifying coverage limits, deductibles, and premiums in insurance forms
Extracting tenant names, unit numbers, rent, and status in rent rolls
Finding clauses, renewal dates, or penalties in contracts
2. Embeddings & Vector Databases enhance accuracy
Unstract converts documents into vector embeddings, enabling:
Semantic search
Context retrieval (“retrieve the correct section before extraction”)
Multi-page reasoning and cross-referencing
This is critical when similar terms appear in different contexts (e.g., “total premium” vs. “annual premium”).
3. Prompt Studio orchestrates structured extraction
Using prompt engineering, users can define extraction rules in plain English. Example: “Extract policyholder info, claim details, deductible, effective dates, and all checkboxes from the document.”
LLMs then return structured JSON output that downstream systems can consume.
4. Human-in-the-loop validation (HITL) for accuracy
For sensitive use cases—insurance claims, property reports, healthcare forms—Unstract allows humans to review low-confidence fields before finalizing.
This creates enterprise-grade reliability.
Core Components: Prompt Studio, Embeddings, Vector DBs, and Workflows
Unstract’s power comes from its modular ecosystem:
1. Prompt Studio — The Brain of Document Understanding
A no-code environment where users design extraction logic using natural language prompts.
Capabilities:
Build custom parsers for any document type
Test prompts across real samples
View field fill-rates and prompt accuracy
Optimize extraction with iterations
Prompt Studio turns a non-technical team into AI automation creators.
2. Embeddings — Semantic Understanding Layer
Embeddings convert each section of the document into vectors that help LLMs:
Retrieve the right context
Understand multi-page documents
Disambiguate similar terms
Improve extraction accuracy
Unstract supports OpenAI embeddings and others.
3. Vector Databases (Vector DBs)
A Vector DB stores embeddings for fast, intelligent retrieval.
Used for:
Chunk-level retrieval before prompting
Knowledge-grounded extractions
Indexing large volumes of documents
Unstract integrates with Postgres, Pinecone, and other vector backends.
4. Workflows — Deployment and Automation Engine
Once a project is ready, Unstract lets teams automate document understanding at scale.
Workflows allow you to:
Connect to document sources (S3, Drive, Blob Storage, etc.)
Run OCR + LLM extraction pipelines end-to-end
Send structured data into databases (Snowflake, BigQuery, Redshift, Postgres, etc.)
Deploy as an API for real-time document processing
Create ETL pipelines for batch automation
Workflows can also launch custom Q&A apps for internal teams, each secured with SSO.
In Summary
Unstract is the intelligence layer that transforms raw OCR output into meaningful, structured information using LLMs. Where LLMWhisperer reads documents, Unstract understands them.
Together, they create a next-generation AI document automation ecosystem capable of handling:
Long, complex documents
Multi-page reports
Financial tables
Insurance forms
Contracts
Handwritten and scanned records
Unstract in Action
To demonstrate how Unstract turns raw OCR output into structured, machine-ready data, we tested it on one of the most challenging document types: a scanned, handwritten contract form—tilted nearly 30°, filled with multi-column text, handwritten entries, dense legal clauses, and uneven print quality.
This is the kind of document that routinely breaks traditional OCR and RPA systems. Rotation, handwriting, shadows, mixed formatting, and unpredictable spacing lead to broken outputs. But with LLMWhisperer + Unstract, the pipeline remains fully intact: layout preserved, handwriting captured, and the entire structure interpreted accurately.
1. Build a Prompt Studio Project
Inside Unstract’s Prompt Studio, we created a lightweight extraction project designed specifically for the scanned contract. No coding, no template design—just natural-language instructions.
Because the OCR output is layout-preserving, Prompt Studio can reason across tilted sections, uneven spacing, and multi-line handwriting with impressive consistency.
After a few iterations inside the testing panel, fill rates stabilized, and the extracted fields matched the source document with high accuracy.
2. Extract Relevant Data Fields from JSON
Once the prompts were ready, Unstract generated clean, structured JSON representing the contract’s contents. All key sections—including handwritten fields—were extracted with:
Correct line order
Preserved relationships (e.g., which signature belongs to which signer)
Intact table/column structures
Proper date and numeric reconstruction
3. Deploy and Test as an API (Postman Example)
After validating the extraction logic in Prompt Studio, we deployed the project as an Unstract API workflow—again, with no custom backend coding.

Unstract Document Ingestion
Document ingestion in Unstract is designed to support real-world enterprise flows where documents arrive from cloud drives, internal file systems, and automated workflow engines. Unstract provides a unified ingestion layer through Connectors and through n8n-based automation, ensuring that documents move from source → extraction → destination with zero manual handling.
1. Ingestion via Unstract Connectors
Unstract supports ingestion from a wide range of data sources using built-in connectors. These connectors allow systems such as cloud storage, file systems, and databases to push documents directly into extraction workflows.
How Connectors Work
Unstract lets you add connectors in two ways:
From the Connectors dashboard (Settings → Connectors)
Directly inside a workflow when configuring the source or destination
Once added, each connector follows a simple process:
Select the connector type (e.g., S3/MinIO, Google Drive, Dropbox, Azure Blob, PostgreSQL, MySQL, etc.)
Configure authentication fields
Test the connection
Save it for use in ETL pipelines, API deployments, or task workflows
These connectors become the entry points for automated ingestion. For example:
A folder in Google Drive can automatically trigger new extraction jobs
A new file landing in Amazon S3 can be processed through a Prompt Studio project
Files stored in on-premise file systems can be consumed using FileSystem connectors
Extracted data can be routed directly into databases like PostgreSQL or Snowflake
Unstract Document Ingestion via n8n Workflow Automation
Unstract integrates seamlessly with n8n to create fully automated document ingestion pipelines. In this setup, n8n orchestrates the flow of documents, while Unstract and LLMWhisperer handle OCR, preprocessing, and structured extraction.
Steps in the n8n + Unstract Ingestion Workflow
8n retrieves new documents from configured sources (email inboxes, cloud drives, APIs, or shared folders).
n8n sends the document to LLMWhisperer for OCR and layout-preserving preprocessing.
The OCR output is passed to an Unstract API (built from Prompt Studio) for structured JSON extraction.
n8n routes the extracted JSON to downstream destinations such as Slack, Google Sheets, databases, or accounting systems.
You can watch the full workflow demonstration in the official webinar:

Unstract API Hub: Document Splitting & Classification
Unstract’s API Hub provides a suite of intelligent, production-ready APIs that solve one of the most difficult challenges in document management: automatically splitting multi-document PDFs and classifying document types without templates, rules, or manual effort. Built using a blend of Vision AI and LLM-driven semantic analysis, these APIs work across every industry and document format.
The Document Splitter API is engineered for real-world, mixed PDFs—loan packages, insurance claim bundles, logistics files, onboarding packets, tax folders, and more. Instead of relying on page numbers or keyword rules, the API uses advanced machine-learning models to detect natural document boundaries based on layout, structure, visual cues, and semantic meaning.
When you submit a multi-document PDF, the API returns:
Individual PDFs, each corresponding to a split document
A ZIP file containing all extracted documents
A detailed JSON boundary report (document type, page ranges, header/footer text, entities, date ranges, etc.)
This approach eliminates the need for manual page selection or template configuration—a critical advantage when document sets vary in order, length, and formatting.
Key Features
High-Accuracy Vision Model Boundary Detection Two-pass AI analysis enables reliable detection of document breaks, achieving confidence scores of 0.9 or higher. Ideal for inconsistent scans, rotated pages, watermarks, and mixed-resolution files.
Fast Processing for Large PDFs Handles 100+ page, multi-document files in minutes. Optimized pipeline ensures consistent performance even when scaling to thousands of files.
Dynamic Windowing Technology Automatically adapts to PDFs of any size or complexity—whether you’re splitting a 10-page insurance packet or a 500-page regulatory submission.
Enterprise-Grade Security & Compliance Supports secure, encrypted processing with compliance across HIPAA, GDPR, SOC 2, and industry-standard privacy requirements.
Industry-Agnostic Operation Works for banking, insurance, healthcare, logistics, education, real estate, BPOs, and government workflows—no custom training required.
AI Classification API
The API Hub also offers document classification endpoints. These identify the type of each document—such as:
Loss Run Summary
ACORD 125 / 140 / 126
Payslip
KYC Form
Tax Form (e.g., 1040, 990)
Onboarding Documents
Shipping Manifests or Bills of Lading
Classification works even when documents vary by layout, language, orientation, or scan quality. This makes it suitable for automated foldering, indexing, routing, and downstream workflow orchestration.
These classification APIs integrate smoothly with:
Document Management Systems (DMS)
ETL pipelines
RPA and automation tools
Workflow engines like n8n
Ingestion platforms (S3, GDrive, Dropbox)
API Endpoints
The PDF Splitter API offers three primary endpoints:
POST: /api/v1/doc-splitter/documents/upload Uploads the combined PDF and initiates the splitting job.
GET: /api/v1/doc-splitter/jobs/status Checks the job status using the returned job_id.
GET: /api/v1/doc-splitter/jobs/download Fetches the ZIP file containing separated PDFs and the JSON boundary metadata.
Postman Workflow (High-Level)
Upload Send the mixed PDF via POST → receive a job_id.
Status Polling Query the status endpoint until the job shows as “completed”.
Download Use the same job_id to download the ZIP containing:
Unstract Document Classification for Document Management
Modern document management systems depend heavily on accurate, automated classification—especially when dealing with large volumes of invoices, policies, claims, contracts, statements, onboarding packets, and scanned submissions. Unstract brings a practical, enterprise-ready approach to this challenge by combining Prompt Studio, LLMWhisperer, and API Deployments into a unified classification pipeline.
Using Prompt Studio to Classify Documents
Prompt Studio acts as the intelligence layer of Unstract’s classification engine. Instead of building and training a custom machine-learning pipeline, teams simply write natural-language prompts to describe classification rules.
For example, a classification prompt can identify whether a file is:
An invoice
A claims document
An insurance policy
A contract
A bank statement
An ACORD form
This approach allows organizations to classify both broad categories and highly specific subtypes—without building templates or rules.
Write classification prompts that instruct the LLM to determine document type based on content and structure.
Run test executions to view classification accuracy.
Validate results using layout-preserved OCR from LLLMWhisperer (ensuring consistent input for the LLM).
Prompt Studio eliminates the fragility of traditional keyword-based classifiers by grounding classification in semantic understanding.
Exposing Classification Logic as an API
Once the classification prompts are tested and approved, Unstract allows the entire logic to be deployed as an API with a single click.
The deployed API:
Accepts PDFs, scans, photos, and documents of any format
Automatically applies OCR (via LLMWhisperer)
Runs the cleaned text through the classification prompt
Returns structured JSON containing the document type
This makes it effortless to integrate classification into enterprise workflows.
Example JSON Output
{
“document_classification”: {
“classification”: “BANK”
}
}
Where this API can be used
Auto-sorting documents as they arrive in S3, GDrive, Dropbox, or internal file systems
Routing incoming claims to the correct insurance queue
Feeding documents into an ERP, CRM, or DMS for categorization
Classifying bulk historical archives during digital transformation
The API removes manual sorting entirely and enables large-scale automated processing.
Integration with DMS Tools for Automated Sorting & Metadata Tagging
Unstract’s classification API integrates seamlessly with:
Document Management Systems (SharePoint, Alfresco, OpenText)
Workflow engines (n8n, Airflow, Zapier)
Storage systems (S3, GCS, Azure Blob, Dropbox, GDrive)
Enterprise ETL systems and warehouse platforms
A typical automated workflow looks like this:
Documents arrive in a storage bucket.
A workflow automation tool (n8n, Airflow, etc.) retrieves each file.
The file is sent to the Unstract Classification API.
The API returns the document type as structured JSON.
Based on this value, the automation:
Places the document into the correct folder
Adds metadata tags to the DMS
Sends the file to downstream extraction workflows
Routes documents to the correct compliance or business teams
Because LLMWhisperer preprocesses every file (OCR, layout normalization, table\form preservation), even poorly scanned, multi-language, or handwritten documents are classified reliably.
