These Telegram bots work with the material a course actually gives you: they summarise recorded lectures and documents, turn your own notes into flashcards and review questions, and answer questions about a PDF.

We did not run these bots on test documents; the list rests on what can be checked in the open. For each bot we confirmed on its t.me page that it is a live bot, found the service's own site or documentation that links to it, and took prices, free limits and interface languages from there. For course material we also checked where your files go in (the chat or a separate app), what the privacy policy says about keeping uploads and training models, and how you pay after the free start. Bots carrying the names of ChatPDF, AskYourPDF and similar services were dropped: the owners of those brands do not confirm them.
Bots for course material do one of three jobs, and this list is still short: four bots for now. Summaries come from SumItUp, which takes a YouTube lecture, an audio file up to three hours or a PDF, Word or PowerPoint file and returns a structured summary you can question with /chat; treat it as a map of where the important part is, not as the lecture itself. Flashcards from your own notes come from Microstudy AI, which builds spaced-repetition cards from a topic or from PDF, text and Markdown files (its documentation ties uploads to your access level) and exports them to Anki, and from PupilBot, which writes questions from pages you photograph or import in its web or iPhone app and sends each one in Telegram when it is due. Questions about a single PDF go to Ask PDF AI: 20 free questions, then credits sold only for TON.
We found no official Telegram bot for ChatPDF, AskYourPDF, Quizlet, Knowt, NotebookLM, Otter or Notta. Bots that use those names exist, but the companies behind the brands do not confirm them, and course files are not something to hand to a bot that only borrows a name, so they are not listed.
Ask for the page or the passage behind an answer. A reply without a reference cannot be cited or verified, and these tools misread tables and formulas more often than plain prose. A scanned PDF without a text layer is only a picture to a bot that reads PDFs, so run it through an OCR bot first; PupilBot and SumItUp accept photos directly. And an uploaded file leaves your device, so check what happens to it: SumItUp's privacy policy says content is not stored after processing, Microstudy AI keeps materials encrypted and out of model training, PupilBot keeps them until you delete them, and Ask PDF AI publishes no privacy policy. Anything confidential stays off all four.
No - cite the document. Ask the bot for the page, open it and check the sentence yourself before it goes into your text.
A bot that reads PDFs needs a text layer, so run a scan without one through an OCR bot first and upload the result. PupilBot builds questions from photographed pages, and SumItUp accepts photos too.
A public textbook, yes. Anything unpublished, personal or under an institution's confidentiality rules should stay off a third-party service.
