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.

Every number here — 1✦ per question, 3 questions, 30 minutes — is the actual runtime limit, not marketing rounding.

See the difference

The whole flow inside one Telegram chat — send a PDF, get a summary, ask grounded questions.

The full flow, start to finish

You send

A text-based PDF — say a 22-page rental agreement — sent to @vustSummaryBot as a document upload, directly in the chat.

You get, then chat

A bullet summary of the agreement with a "💬 Ask about this PDF" button under it. Tap it, then type "What's the notice period to move out?" — the next plain message is treated as a question about that PDF, and the bot answers from the document text.

A grounded answer, in-chat

You ask

"Does the lease allow subletting?"

1✦ charged, answer in Telegram

"Clause 9 requires the landlord's written consent before subletting; it is not permitted otherwise." If a question isn't answered anywhere in the PDF, the bot says so instead of inventing a clause.

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

01Send the PDF to @vustSummaryBot as a document

A text-based PDF (one where you can select the words) — the bot summarizes it first.

02Tap '💬 Ask about this PDF' under the summary

This arms question mode: your next plain-text message is treated as a question about that document, 1✦ each.

03Ask 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.

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.
