Cake for Intelligent Document Processing
Extract, structure, and act on unstructured content at scale using Cake’s composable AI stack. Automate document processing with open-source OCR, LLMs, and orchestration built for enterprise compliance.







Overview
Documents still power critical workflows across industries—from invoices and contracts to claims, applications, and reports. But traditional OCR and rule-based systems are brittle, expensive, and hard to adapt. Intelligent Document Processing (IDP) powered by LLMs and open-source tools makes it possible to unlock that data at scale.
With Cake, you can ingest PDFs, Word files, or scans, extract and structure content using open-source OCR and LLMs, and feed results directly into downstream workflows. Whether you’re classifying documents, pulling key fields, or summarizing multi-page reports, Cake gives you a modular, cloud-agnostic stack to do it securely and repeatably.
You can integrate best-in-class tools like PyMuPDF, Hugging Face, and LangChain—then orchestrate the entire pipeline using Kubeflow and track results with built-in observability. It’s everything you need to move from static documents to AI-powered workflows—without lock-in or overhead.
Key benefits
✓ Automate document processing at scale: Extract, structure, and act on unstructured content using open-source components.
✓ Reduce manual effort and costs: Eliminate repetitive reviews and handoffs with reusable, low-latency pipelines.
✓ Use cutting-edge LLMs and OCR tools: Integrate the latest models and libraries without vendor delays.
✓ Deploy securely and flexibly: Run workloads in any environment, with full control over data access and compliance.
✓ Track performance and outcomes: Monitor model quality and track extracted fields across versions.
Example use cases
Teams use Cake’s IDP stack to streamline content-heavy workflows:
Invoice and form extraction
Parse structured and semi-structured forms to extract fields like totals, dates, and customer IDs.
Contract summarization and classification
Use LLMs to identify document types, extract clauses, or summarize key terms across large contract volumes.
Insurance, healthcare, or legal document intake
Automate intake and routing of documents based on content, structure, or urgency.
Onboarding and identity verification
Extract and validate key fields from documents like passports, licenses, and utility bills to streamline KYC and onboarding workflows.
Regulatory compliance checks
Scan documents for required disclosures, missing terms, or risky language to ensure alignment with industry regulations and internal policies.
Audit-ready document archiving
Automatically extract, tag, and store key document data in structured formats to support audit trails, record retention, and regulatory reviews.

Frequently asked questions
What is intelligent document processing (IDP)?
Intelligent document processing (IDP) uses AI to extract, classify, and structure information from unstructured or semi-structured documents. It combines technologies like OCR, natural language processing (NLP), and machine learning to automate tasks traditionally handled by manual data entry.
How does Cake support IDP workflows?
Cake provides a composable AI infrastructure that makes it easy to integrate OCR engines, LLMs, vector databases, and RAG pipelines into a secure, traceable document processing workflow. Teams can quickly build, evaluate, and scale IDP applications using open-source tools—without reinventing the stack.
Can Cake handle sensitive documents with compliance requirements?
Yes. Cake’s platform is designed with enterprise-grade security and compliance in mind. It supports HIPAA and SOC 2–ready workflows and allows you to deploy components in your own VPC, ensuring that no data ever leaves your environment.
What are common use cases for IDP?
IDP is used across industries for automating high-volume, document-heavy processes. Common examples include invoice processing, claims intake, loan document analysis, contract summarization, and onboarding workflows that require KYC document extraction.
Which tools can I use with Cake for document understanding?
You can bring your own stack or choose from Cake’s supported open-source tools, including Tesseract or PaddleOCR for extraction, LangChain or LlamaIndex for retrieval, LiteLLM for model routing, and Langfuse or Prometheus for observability. Everything is pre-validated to work together.
