Hi everyone šŸ‘‹

Most OCR tools struggle with complex documents—crumbling tables, garbled formulas, or unstructured text. Need clean data for RAG or apps? Good luck.

So I built Mistral OCR (https://www.mistralocr.app/) using Mistral AI’s document understanding models. It doesn’t just scan—it understands the document’s structure, and extracts: āœ… Text (plain/formatted) āœ… Tables (pixel-perfect JSON with headers 🧮) āœ… Math formulas (LaTeX-ready via Mistral’s ML pipeline) āœ… Images (preserved or extracted)

Why Mistral AI? Their models nail context-aware parsing—unlike rigid OCRs, Mistral’s tech handles:

  • Cursed PDFs(scanned/watermarked/warped text)
  • Mixed layouts (research papers with tables + formulas)
  • 20+ languages (English, Japanese, Mandarin, Spanish...)
  • Structured JSON output (directly feeds into RAG/APIs)

See examples → https://www.mistralocr.app/

Why build this? I needed an OCR that could extract RAG-ready data without regex nightmares. Mistral AI’s models finally made this possible—they preserve relationships between text, tables, and formulas, something traditional OCRs butcher.

Who’s using it?

  • Devs automating document workflows
  • Researchers digitizing datasets from papers
  • Teams processing multilingual forms/contracts
  • Anyone frustrated by copying tables from PDFs

Challenge me: Send your worst documents (scanned receipts? handwritten tables?) and I’ll run them through Mistral OCR live.
