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?

Your document is uploaded temporarily to Mistral for OCR processing and is not permanently stored. We do not log or retain any document content.

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.
