Chat with PDF (AI) — frequently asked questions

Is Chat with PDF (AI) really free?

Yes. Chat with PDF (AI) is free forever on Sada Files — no ads, no premium tier, no watermark, no daily cap that pushes you to pay. Every option on this page is available to everyone.

Do I need to sign up or create an account?

No. There is no account system at Sada Files. Open the page, drop your file, pick your options and save the result. History and saved workflows stay on your device.

Is my file uploaded anywhere?

No. Chat with PDF (AI) runs on your device — in your browser using WebAssembly, or inside the free native app. Your file never leaves your computer or phone, which is why there is no upload wait. Cloud AI is optional: only if you switch to it is the document's content sent to the AI service for that one request.

Which formats does Chat with PDF (AI) accept?

Chat with PDF (AI) accepts PDF, Word 97–2003 (DOC), DOCX, ODT / ODS / ODP, RTF, TXT, JPEG, PNG, WebP, AVIF, GIF, BMP, TIFF and HEIC / HEIF. Files are identified by their content, not their extension, so a mislabelled file still works.

Is there a file size or file count limit?

Only what your device can handle. Because processing happens locally there is no server cap, no queue and no "upgrade for larger files" message. Batch as many files as you like.

Can I chain Chat with PDF (AI) with other tools?

Yes. After every result a Continue with… menu lists every tool that accepts this output, and the file is handed over in memory. Save the chain as a workflow and re-run it on hundreds of files, or call it in one API request.

Does Chat with PDF (AI) work on my phone?

Yes. The web app works on Android and iOS browsers, and the free Sada Files app for Android, iOS, Windows, Linux and macOS runs Chat with PDF (AI) fully offline.
