AI PDF Chat · No Signup
Chat With a PDF — No Account, No Web Upload.
Send a PDF to @vustSummaryBot in Telegram and ask questions about it. No signup, no email, no browser dashboard — opening the chat and getting a summary is free. Each follow-up question is priced up front and charged when you send it, up to 3 per PDF, within 30 minutes. We name the cost instead of hiding it.
Limits 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 is priced up front and charged when you send it — capped at 3 per document. That's the whole deal, stated plainly.

Exactly what's free and what's paid — no fake 'unlimited,' no surprise meter.
Who wants no-signup PDF chat
- People tired of signup walls
- Every 'free AI PDF chat' seems to demand an account before the first answer.
- 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 up front and charged on send — 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
'Free' means no account — not free questions
Opening, uploading, and summarizing are free (no card). The follow-up questions are paid — each is priced up front and charged on send — 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.
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 is priced up front and charged when you send it, 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 inside Telegram, and the charge lands when you send the question. 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 at the price stated before you send it.
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 price is stated up front and the charge lands when you send it; 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.
