What file types and languages are supported?

PDFs of every kind, plus Word, PowerPoint, text files, and images, in over 100 languages including CJK, Arabic, Cyrillic and Indic scripts. Scanned PDFs are read with OCR first.

Can it handle tables and math?

Yes. PDF.chat understands tables and equations so you can ask about figures, totals and formulas, and you can export tables as Markdown or CSV and equations as LaTeX.

What output formats can I download?

Plain text, Markdown, Word (DOCX), searchable PDF, CSV, and JSON, plus copy to clipboard.

Are my files private?

Files are processed only to answer your questions and deleted automatically. We never sell or share your documents, and we don't train on them.

Can it read handwriting?

Yes. The premium AI engine reads handwritten notes, forms, and mixed printed and handwritten pages so you can chat with them, and every answer cites the page so you can check it against your original.

Can I chat with long PDFs and large files?

Yes. PDF.chat indexes long documents and retrieves the most relevant pages for each question, so it works on hundred-page reports and books. Larger documents process in the background.

How much does it cost?

There is a free tier you can use without signing up. Paid plans start at $5/month and add more pages, multi-document chat, the highest-accuracy AI models, and API access. One page of a document equals one page.

How is PDF.chat different from other PDF chat tools?

It grounds every answer in your document and cites the exact page so you can verify it, pairs a fast engine for everyday questions with a premium AI engine for hard documents, shows the original beside your conversation, and reads scanned PDFs with OCR.

Do I need to install anything?

No. PDF.chat runs entirely in your browser. Upload a PDF and start chatting, with nothing to download or install.

Is there an API for developers?

Yes. A REST API lets you upload a document and chat with it programmatically, getting back answers with page citations, and can also process documents into text, Markdown, tables, and JSON.

Can it answer questions about charts and images?

Yes. The premium AI engine reads charts, diagrams, and images inside your PDF, so you can ask what a figure shows, summarize a chart, or pull numbers out of a graph, all cited to the page.
