From PDF to JSON
in four steps

A fully automated pipeline from raw document to validated, structured output.

Step 01
📄
Upload Your PDF

Drop any PDF file. PyMuPDF renders every page into a high-fidelity 200 DPI image — preserving tables, layouts, and scanned content.

Vision OCR

Each page image is processed by Gemini 2.0 Flash. It extracts all text and tables into structured Markdown — handling scanned and printed documents.

Step 03
🧠
Define & Extract

Define the fields you need with descriptions and types. LLaMA 3.3 70B at temperature 0 returns a strict JSON object matching your schema.

Step 04
Validate & Correct

Pydantic validates every field against expected types. If errors exist, add a correction hint and re-extract. Then ask anything about your document.

Billing Table Detection

The Markdown is scanned for pipe-tables. Headers are scored against billing keywords — the best match is extracted instantly with zero LLM calls.

Download & Reuse

Export your results as JSON. Save your field schemas for reuse across documents. Edit extracted values inline before exporting.

for document extraction

🔍
Multimodal OCR

Gemini 2.0 Flash reads images, not raw bytes — handling scanned, rotated, and mixed layouts that traditional parsers miss.

Real-time Streaming

OCR streams progress page-by-page via SSE. See exactly which page is being processed in real time.

🎯
Custom Field Schema

Define any fields with keys, descriptions, and types. Import or export schemas as JSON for reuse across documents.

🔄
Re-extraction Loop

Validation errors and correction hints are injected into the next prompt automatically — no manual prompt engineering required.

💬
Grounded Q&A

Ask anything about the document. Answers are grounded in your document's full Markdown — no hallucinations from outside context.

🛡️
Type Validation

Pydantic validates every extracted field against string, number, date, and boolean types — flagging mismatches before you export.

Dual-model architecture

Two specialized AI models in separate layers, each optimised for its specific role.

👁️
Gemini 2.0 Flash — Vision OCR
Reads each page as an image. Handles scanned docs, mixed layouts, and per-page streaming. Outputs structured Markdown with tables intact.
Groq · LLaMA 3.3 70B — Extraction
Temperature 0 for deterministic output. Schema-driven JSON — no hallucinated keys. Re-extraction loop injects errors and correction hints.
🛡️
Pydantic — Validation Layer
Every extracted field is validated against the defined type. Errors surface inline in the UI and are automatically included in re-extraction prompts.
📊
Rule-Based — Billing Detection
Zero LLM cost. Pipe-tables in Markdown are scored against billing keywords. The top match is extracted in milliseconds.
