Chat With a PDF · in Telegram
Ask a PDF Questions — Right Inside Telegram.
Send a PDF to @vustSummaryBot, get a summary, then tap “Ask about this PDF” and ask it questions in the same chat. Answers come from the document itself — 1✦ per question, up to 3 per PDF, within a 30-minute window. No separate app, no account.
Honest scope
Real, but bounded — and we'll say where the edges are
This is genuine document Q&A that works today: the answers are grounded in your PDF's text, not the open web. The bounds are just as real — 3 questions per PDF, a 30-minute window that doesn't extend, and text-based PDFs only (a scanned or image-only PDF has no text to read). It's not an unlimited PDF chatbot, and we won't pretend it is.
See the difference
The whole flow inside one Telegram chat — send a PDF, get a summary, ask grounded questions.
02·Practical use cases
Who chats with a PDF in Telegram
Anyone reading a contract or lease
A specific clause needs a plain answer without re-reading 20 pages.
Send the PDF, get a summary, then ask '@vustSummaryBot, what's the notice period?' — the answer is grounded in the document's actual text.
Students with a dense reading
A course PDF is assigned and one section is the part that matters.
Ask a targeted question about that section and get a two-sentence, grounded answer — up to 3 questions per document.
People who live in Telegram
Opening a website and making an account for one PDF question feels like overkill.
The whole thing happens in a normal Telegram chat — no site, no login, no upload dashboard.
03·How it works
From PDF to grounded answer, in one chat
A text-based PDF (one where you can select the words) — the bot summarizes it first.
This arms question mode: your next plain-text message is treated as a question about that document, 1✦ each.
Grounded answers from the document text; after the cap or the window, resend the PDF to start again.
04·Same tool · in Telegram
Telegram
Send a PDF, ask it questions
@vustSummaryBot · Open @vustSummaryBot, send a text-based PDF, tap 'Ask about this PDF,' and ask up to 3 grounded questions within 30 minutes.
05·Quality & trust
What's live — and what's honest about it
Real document Q&A, grounded in the file
Answers come from the PDF's text, not the open web. Ask something the document doesn't cover and the bot says so instead of inventing an answer.
Bounded on purpose: 3 questions, 30 minutes
A hard cap of 3 questions per PDF and a 30-minute window that doesn't extend. It's real document Q&A, not an unlimited PDF chatbot — and we won't imply otherwise.
Text-based PDFs only — no OCR
A scanned or image-only PDF has no text layer to read; the bot reports no extractable text and suggests pasting the content in. Long PDFs are truncated to their first part for questions.
