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 do cost 1✦ each, capped at 3 per document. That's the whole deal, stated plainly.

A spark (✦) is a small unit of VUST balance. One question = 1✦. Maximum spend on one PDF's questions is 3✦.

See the difference

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 costs 1✦ (a spark — a small unit of VUST balance), 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, 1✦

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.

02·Practical use cases

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 at 1✦ each, so the most one PDF's Q&A costs is 3✦ — cheap and 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.
