Document Intelligence for RAG and LLM Pipelines

Structured extraction for the systems that consume your documents — not lossy conversion.

The problem: Markdown is not structured data

The RAG ecosystem has converged on a common pattern: parse documents into Markdown, chunk the text, embed it, and retrieve it. Tools like LlamaParse and Unstructured are optimized for this pipeline. They are fast, well-integrated with vector databases, and effective for text-heavy retrieval tasks.

But Markdown is a presentation format, not a data format. When a document with financial tables, nested structures, and typed fields is converted to Markdown, the result is readable text that has lost its schema. Column headers become pipe-delimited strings. Merged cells disappear. Numeric fields lose their types. Hierarchical relationships flatten.

For retrieval-only workflows — "find the paragraph that answers this question" — Markdown may be sufficient. For workflows that need to extract, validate, and act on structured data from documents, the Markdown intermediate step destroys the information you need.

Structured JSON with schema enforcement

anyformat does not convert documents to Markdown. It extracts structured data directly into schema-enforced JSON.

You define the fields, their types, and their relationships. The system extracts values that conform to your schema, with every field validated against its expected type and constraints. The output is deterministic: the same schema produces the same JSON structure every time, regardless of document layout.

This makes anyformat output directly consumable by downstream systems, databases, APIs, and LLM workflows without parsing, transformation, or post-processing. The data arrives structured because it was extracted structured — not converted from an unstructured intermediate.

Use cases: beyond RAG retrieval

LLM workflow input: When LLMs need to reason about document data — not just retrieve text — they need structured input. A financial model that processes quarterly earnings needs revenue, EBITDA, and margin fields in a predictable schema, not a Markdown table that the LLM has to parse again. anyformat delivers fields the LLM can use directly.

Knowledge base construction: Building a knowledge base from thousands of documents requires consistent structure. If every document produces a different JSON shape depending on how the Markdown was parsed, your knowledge base is unreliable. Schema enforcement means every document of a given type produces the same field structure, making aggregation and querying reliable.

Agentic systems: Autonomous agents that process documents as part of multi-step workflows need predictable, typed data. An agent that receives Markdown has to interpret it. An agent that receives schema-enforced JSON can act on it immediately. The difference between interpretation and action is the difference between a fragile system and a robust one.

Cross-referencing and validation: When extracted document data needs to be matched against internal databases — invoices against purchase orders, claims against policies, applications against records — structured fields with confidence metadata make matching reliable. Markdown makes matching a string-parsing problem.

Deterministic schemas, predictable output

One of the most underappreciated requirements in document intelligence pipelines is determinism. When the same document type produces different output structures depending on parsing artifacts, downstream systems break unpredictably.

anyformat schemas are deterministic. Define a schema once, and every document processed against that schema produces the same JSON structure. Fields that cannot be extracted are explicitly marked as null with a confidence score, not silently omitted. Your integration code can rely on the shape of the data.

Confidence scoring for every field

Not every extracted value deserves the same trust. A clearly printed invoice number extracted from a consistent position has different reliability than a handwritten note parsed from a degraded scan.

anyformat assigns calibrated confidence scores to every extracted field. These scores are calibrated against human judgments, not raw model probabilities. Downstream systems can apply thresholds: auto-accept above 95%, route to review between 80% and 95%, flag for manual entry below 80%.

For LLM pipelines, confidence scores enable selective grounding — the LLM can be told which fields are reliable and which are uncertain, improving the quality of downstream reasoning.

100+ formats, one API

Documents arrive as PDFs, scans, Word files, Excel spreadsheets, PowerPoint decks, HTML pages, images, and email attachments. anyformat processes 100+ formats through the same extraction pipeline with the same schema, the same confidence scoring, and the same JSON output.

No format-specific preprocessing. No separate parsers for different file types. One API, one schema, structured JSON out.

API and webhooks for pipeline integration

anyformat provides a REST API for synchronous extraction and webhooks for asynchronous pipeline integration. Submit documents via API, receive structured JSON responses. Configure webhooks to push results to your systems when processing completes.

For high-volume pipelines, batch processing endpoints handle thousands of documents with consistent throughput. Rate limits, retry logic, and error handling are built into the API layer, not left to your integration code.

The difference: extraction vs. conversion

LlamaParse converts documents for RAG ingestion. Unstructured chunks documents for vector search. Both are conversion tools — they transform documents into text-oriented formats optimized for retrieval.

anyformat is an extraction tool — it pulls structured, typed, confidence-scored data from documents into schemas you define. The output is not text to be searched. It is data to be used.

If your pipeline needs to find relevant passages in documents, RAG tools work. If your pipeline needs to extract specific fields, validate them, and feed them into systems that expect structured data, anyformat is built for that.

Build intelligence pipelines on structured data

Your documents contain structured information. Your downstream systems expect structured input. The step in between should not involve converting structure into text and hoping to reconstruct it later.
