AI Document OCR
Extract text and structured data from PDFs, images, and documents using Mistral AI OCR. Private processing — your documents are never stored.
Quick Answer
AI Document OCR converts PDFs, images, and Office documents into clean, table-preserving markdown using Mistral OCR, and can also extract structured JSON with custom or preset schemas for invoices, research papers, receipts, and charts. Files up to 50MB are processed securely and deleted immediately after extraction — nothing is permanently stored. Free to use, no registration required.
How It Works

Choose Basic OCR to extract all text, or Annotated OCR to extract structured data
For Annotated OCR, select a preset schema (invoice, paper, etc.) or enter a custom JSON schema
Click Extract and wait — results appear as rendered markdown with download options

Frequently Asked Questions
What file formats does the AI Document OCR support?
The tool supports PDF, PNG, JPEG, AVIF, DOCX (Word), and PPTX (PowerPoint) files up to 50MB in size.
What is Annotated OCR?
Annotated OCR uses JSON schemas to extract structured data alongside the text. For example, you can extract an invoice into a JSON object with vendor, total, and line items, or a research paper into title, authors, and abstract.
How accurate is the OCR?
The tool uses Mistral OCR (mistral-ocr-latest), which achieves state-of-the-art accuracy on PDFs and scanned documents. Confidence scores are included in the output when enabled.
Can I extract data from invoices automatically?
Yes. Switch to Annotated OCR mode, select the Invoice preset, and the tool extracts vendor, invoice number, date, line items, totals, and tax into a structured JSON file.
Is my document stored after processing?
No. Your document is uploaded temporarily to Mistral solely for OCR processing and is immediately discarded afterward. We do not log, store, or retain any document content. Your files and their extracted text are never saved on our servers.
Is my document used for AI training?
No. Documents uploaded for OCR are processed in real-time by Mistral AI and are not stored, logged, or used for model training. Your intellectual property remains private.
How is this different from the browser-based OCR tool?
The browser-based OCR at /convert/ocr uses Tesseract.js and runs entirely in your browser. This AI Document OCR tool uses Mistral's server-side OCR model, which offers significantly higher accuracy, supports more file types (PDF, DOCX, PPTX), and can extract structured data using annotation schemas.
