Pricing

Pricing model: Freemium

Free use covers two documents a day with no account needed. The Plus subscription lifts the cap, but its price is not on any public page (the site has no pricing URL) and appears only at the in-app upgrade step.

Overview

About ChatPDF

ChatPDF answers questions about an uploaded file, whether PDF, Word, PowerPoint, Markdown or plain text, and tags each answer with the page it came from so it can be checked. It summarises, translates and compares several documents in one chat, and the same account now covers YouTube and website chat, flashcards, slides, an AI writer and an AI detector aimed at students and researchers. Desktop installers exist for Mac and Windows, and a documented REST API exposes the upload-and-ask flow with a limit of 2,000 pages or 32 MB per file. It is run by ChatPDF GmbH in Berlin.

How we collect these records

Editorial verdict

Pros & cons of ChatPDF

medium confidence

The quickest way to interrogate one long PDF without building retrieval yourself, and the page-level citations are what keep it honest. But ChatGPT and Claude now read PDFs natively, so ChatPDF only earns its subscription if you need those citations, the multi-file view, or the API.

Pros

answers cite specific pages, so you can check them instead of trusting them
handles Word, PowerPoint, Markdown and text files, not only PDF
REST API supports streaming and multi-turn conversations
free tier works with no account and no card

Cons

two documents a day on free runs out fast during real research
Plus pricing is not published anywhere on the site
no team plan, SSO or shared document library
hard per-file limit of 2,000 pages or 32 MB

Best for

students and researchers pulling verifiable quotes out of long papers
checking claims inside a contract or report you did not write
developers wanting a hosted PDF-Q&A endpoint instead of rolling their own RAG stack

Not for

scanned or handwritten documents where OCR quality decides the answer
workflows that need editing or redlining, not just questions
teams needing shared libraries, permissions or audit logs

Watch out: Prices vary by region and only appear once you hit the paywall inside the app, so budget from your own checkout screen rather than from a review site.
