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 — each question priced before you confirm, 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.
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.
From PDF to grounded answer, in one chat
- 01
Send the PDF to @vustSummaryBot as a document
A text-based PDF (one where you can select the words) — the bot summarizes it first.
- 02
Tap '� Ask about this PDF' under the summary
This arms question mode: your next plain-text message is treated as a question about that document — each priced before you confirm.
- 03
Ask up to 3 questions within 30 minutes
Grounded answers from the document text; after the cap or the window, resend the PDF to start again.
Send a PDF, ask it questions
Open @vustSummaryBot, send a text-based PDF, tap 'Ask about this PDF,' and ask up to 3 grounded questions within 30 minutes.
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.
Frequently asked questions
How do I chat with a PDF inside Telegram?
Open @vustSummaryBot, send your PDF as a document upload, and let it summarize. If the summary came from a PDF file, a "💬 Ask about this PDF" button appears under the result. Tap it once, and your next plain-text message is treated as a question about that document — the answer arrives right in the same chat.
Do I need to install anything or create an account?
No. This runs entirely inside Telegram — the app you likely already have. There's no separate website to log into, no email signup, and no uploading your document to a browser dashboard. The PDF goes to the bot in a normal chat message.
How many questions can I ask, and for how long?
Up to 3 questions per PDF, and only within 30 minutes of when the summary was delivered — the window is fixed and does not extend when you ask a question. After the third question, or once 30 minutes pass, you resend the PDF to start a fresh round. Each question shows its exact price before you confirm.
Can it read a scanned PDF or a photo of a page?
No — and this matters. It reads the actual text layer of a PDF. A scanned or image-only PDF has no selectable text, so the bot can't extract it; it will tell you the PDF has no extractable text and suggest pasting the content in directly. Use a text-based PDF (one where you can select and copy the words).
Does it answer from the document or from the open web?
From the document. Answers are grounded in the text of the PDF you summarized, not the open internet. If something isn't in the PDF, the bot says it can't find it rather than guessing — that's the point of grounded document Q&A.
What happens with a very long PDF?
Long documents are truncated to their first portion for the question step, and the bot adds a note that only the first part is available for questions. For a very long file, ask about material near the front, or split the PDF and summarize the section you care about.
