Honesty first

'Free' means no account — not free questions

Plenty of 'free AI PDF chat' pages mean free until a signup wall or a hidden per-message meter. Here, free means the real friction is gone: no account, no email, no upload to someone's website — you just message a Telegram bot, and getting a summary costs nothing. The follow-up questions are paid — each shows its exact price before you confirm — capped at 3 per document. That's the whole deal, stated plainly.

Each question shows its exact price before you confirm; with at most 3 questions per PDF, the total spend per document stays capped and visible.

Exactly what's free and what's paid — no fake 'unlimited,' no surprise meter.

What 'free' honestly means here

Free

Opening the chat, sending the PDF, and getting the summary need no account, no email, and no card — you just message @vustSummaryBot in Telegram.

Not free

Each follow-up question about the PDF is paid — the exact price is shown before you confirm — capped at 3 questions per document. We'd rather name that up front than bury a paywall behind a fake 'free' banner.

A real question, answered

You send + ask

A course-notes PDF, then: "Summarize the argument in section 3 in two sentences."

Grounded answer, at the price you confirmed

A two-sentence answer drawn from section 3's text. Ask something the PDF never covers and the bot says it isn't in the document — it won't fabricate an answer to look helpful.
Practical use cases

Who wants no-signup PDF chat

Here, opening the chat, sending the PDF, and getting a summary need no account, email, or card — you just message @vustSummaryBot.
Anyone with one quick PDF question
One clause or one paragraph needs clarifying — not a whole subscription.
Ask up to 3 questions, each priced before you confirm — the hard cap of 3 keeps one PDF's Q&A predictable, never a surprise bill.
Privacy-minded readers
Uploading a document to an unfamiliar website feels risky.
The PDF goes to a Telegram bot as a normal chat attachment — no browser upload dashboard to create an account on.

What's live — and what's honest about it

'Free' means no account — not free questions

Opening, uploading, and summarizing are free (no card). The follow-up questions are paid — each shows its price before you confirm — up to 3 per PDF. We name the cost instead of dressing a paywall as 'free unlimited chat.'

No signup, no web upload

There's no form, no email verification, and no third-party dashboard. If you use Telegram, you already have everything needed.

Text-based PDFs only — no OCR

Scanned or image-only PDFs have no readable text and return a 'no extractable text' message. Use a PDF where you can select and copy the words.

FAQ

Frequently asked questions

Is chatting with a PDF here actually free?

Opening it is: no account, no email, no card, no web upload — you message @vustSummaryBot in Telegram and get a summary at the free line. The follow-up questions about that PDF are not free — each shows its exact price before you confirm, up to 3 per document. We name the cost rather than dress a paywall as 'free unlimited chat.'

Do I have to sign up or verify an email?

No. There's no signup form, no email verification, and nothing to upload to a browser dashboard. If you already use Telegram, you already have everything you need — the PDF goes to the bot as a normal chat attachment.

How much does a question cost?

Each question is paid from your prepaid VUST Balance, and the exact price is shown in the bot before you confirm. It's deliberately cheap per question, but it isn't zero — and a single PDF's Q&A won't ever surprise you with a big bill: at most 3 questions per document, each confirmed at the price shown.

Why cap it at 3 questions instead of unlimited?

The cap keeps the per-document cost bounded and predictable — for you and for us. It's a real limit, not a soft nudge: after the third question, or once the 30-minute window closes, you resend the PDF to start a new round. If you need long, open-ended chat on one document, a dedicated web PDF tool may fit better.

Will it work on any PDF I have?

It works on text-based PDFs — files where you can select and copy the words. A scanned PDF or a photo saved as PDF has no text layer, so the bot can't read it; it will say the PDF has no extractable text and suggest pasting the content in instead. No OCR is performed.

Is there a free daily allowance for the questions?

The question step is paid — each question's exact price is shown before you confirm; there isn't a separate 'free question' pool for it. What's genuinely free is getting started — the chat, the upload, and a summary — so you can see the document and decide whether the follow-up questions are worth it.
