The short answer

ChatPDF alternative that keeps your PDF on your device: ChatPDF uploads and stores your PDF (encrypted; you can delete it), and its free plan covers 2 documents a day. OneClickPDF's Chat with PDF reads the PDF in your browser and sends only its extracted text to Google Gemini; you get 3 free questions, then a $0.99 day pass with a fair-use allowance. Answers cite pages.

ChatPDF made chatting with a PDF popular: upload a document, ask questions, click a citation to jump to the source. It stores the uploaded file in your account. OneClickPDF's Chat with PDF works differently: the PDF is read in your browser and only its text goes to the AI.

When to pick ChatPDF instead

Pick ChatPDF if…

  • You want to chat across several PDFs at once, or keep your chat history: ChatPDF does both with a free account.
  • You ask more than a few questions a day on a free plan: ChatPDF's covers 2 documents a day; ours gives 3 free questions.

Why pick OneClickPDF

  • The PDF stays on your device: text is extracted in your browser and only that text is sent to Google Gemini.
  • 3 free questions, then $0.99 for 24 hours with a fair-use allowance — no subscription.
  • Answers give the page numbers they come from.
  • PDF Summarizer and Question Generator use the same day pass.
  • 59 PDF tools in the same place: merge, split, compress, sign, OCR and more.

Why people look for a ChatPDF alternative

  • Your PDF is uploaded and stored by ChatPDF (encrypted, it says, with an option to delete it).
  • The free plan covers 2 documents a day; unlimited documents need ChatPDF Plus.

ChatPDF is good at what it does, and its free plan is generous for light use. The design choice that matters for confidential documents is that the PDF itself is uploaded and stored, with its images, metadata and everything else in it.

OneClickPDF's Chat with PDF opens the PDF in your browser, pulls out the text there, and sends only that text to Google Gemini to answer your questions. The file itself isn't uploaded. You get 3 free questions; after that a $0.99 pass covers 24 hours of Chat, Summarizer and Question Generator, up to a fair-use allowance, with no subscription.

If you need multi-document chat or saved history, ChatPDF is the better choice; if you want the file to stay on your device, use OneClickPDF.

Frequently Asked Questions

Is there a ChatPDF alternative that doesn't upload my PDF?
Yes. OneClickPDF's Chat with PDF reads the PDF in your browser and sends only its extracted text to Google Gemini, not the file. You get 3 free questions, then a $0.99 day pass.
Is ChatPDF free?
It has a free plan that covers 2 documents a day, and needs no account (a free account adds saved history and multi-document chats). ChatPDF Plus gives unlimited documents (October 2026).
How much does OneClickPDF's Chat with PDF cost?
The first 3 questions are free. After that, $0.99 buys 24 hours of Chat with PDF, PDF Summarizer and Question Generator, with a fair-use allowance; when it's used up you can buy another pass. There's no subscription and no account.
Is it safe to chat with a confidential PDF?
With OneClickPDF the PDF file stays on your device; only its text is sent to Google Gemini to answer, and we don't store it. Whether sending the text to an AI service is acceptable for your document is your call; for the strictest cases, don't use any AI chat.
Can I chat with a scanned PDF?
Yes. When a PDF has no text, OneClickPDF's Chat with PDF offers to read its pages with OCR in your browser first (16 languages); only the recognised text is sent to Google Gemini. Text read from a scan may contain mistakes.
