Chatpdf
A three-hundred-page report starts answering questions instead of being read end to end: ChatPDF names the page behind each answer and opens it next to the conversation so it can be checked.

Overview
Finding one clause buried in a three-hundred-page report takes seconds instead of an evening of reading. The file is dropped straight into the browser, with no account and no install, and ChatPDF answers plain questions while naming the page each statement comes from. Clicking a citation scrolls the document, open beside the conversation, to the original passage. A folder gathers several files into one discussion, enough to compare two contracts or cross-check five papers without switching tabs. Questions can be asked in a language other than the document's, and the same content then turns into flashcards or slides. Among AI chatbots and assistants, ChatPDF holds one line: every answer stays attached to the source it came from, whether a page of the document, a video or a paper the tool found itself.
Key features
- Chat with an uploaded document, with the pages used flagged inside each answer.
- Side-by-side view of document and conversation, where a clicked citation scrolls the PDF to the passage.
- Folders that bring several files into a single discussion.
- Support for everyday office formats, plus YouTube videos and web pages pasted into the input field.
- Academic search that surfaces papers, shows the journal quartile and summarises with links back to the sources.
- Conversion of a document into flashcards or a presentation, exportable to Anki and PowerPoint.
Best use cases
- A student uploads a textbook chapter and builds a card deck before the exam.
- A researcher triages a stack of papers by asking each one whether it addresses the question.
- A lawyer locates the exact clause in a contract and checks the cited page before reusing it.
- A consultant puts three reports in one folder and draws out where they disagree.
- A reader asks questions in their own language about technical documentation written in English.
- A trainer turns course material into slides ready to project.
Pros
- The first document can be queried without creating an account, straight from the browser.
- The free plan does not expire after a trial period and covers two documents a day.
- A share link opens the document to someone with no account, without showing them the conversation, and can be revoked afterwards.
- A documented API brings the same page-cited answers into an in-house application.
