What's Live

A structured summary you can question — and verify

vust summarizes a long document into sections and key points, lets you ask follow-up questions in chat, and cross-checks risky conclusions with the Council. One question across many PDFs, and clickable paragraph citations, are outside that scope — so we don't claim them.

For legal or financial text, treat the summary as a first pass and verify the consequential parts.

Research workflow

One paper at a time — not a scholarly-corpus search

  1. 1. Find: search for candidate sources, then open and read the original paper.
  2. 2. Triage: summarize one permitted PDF to identify methods, findings, and limitations worth reading closely.
  3. 3. Verify: check each claim against the exact passage and surrounding context.
  4. 4. Cite: cite the paper itself under your required style; do not cite a generated summary as if it were the source.
Best for
Understanding and checking an individual paper you already selected.
Not ideal for
Corpus discovery, multi-PDF screening, deduplication, PRISMA flow, or automatic bibliography management.
In short
Use vust to inspect a paper, not to pretend the literature search or screening happened.
Specimens

See the difference

Common documents, and what you actually get back.

Report → key points & risks

Your document

A 40-page quarterly report you need the gist and the risks from — fast.

What you get

A structured summary with sections and key points, then follow-up questions answered in chat so you can probe the parts that matter.

Dense paper → readable brief

Your document

A long research paper you don't have time to read end to end.

What you get

A clear brief of the core findings, with the option to ask for detail on any section in plain language.

Contract → understand before signing

Your document

A long contract where you need to grasp the obligations before acting.

What you get

A structured read of the document, plus a Council cross-check on the consequential clauses — a first pass that flags what to verify, not legal advice.

Read a long PDF without trusting it blindly

A sixty-page report lands on your desk with a decision due tomorrow. You need two things from it: what it says overall, and whether one specific claim is really in there. Skimming gives you neither. A summary you cannot check gives you a confident answer you cannot defend in the meeting.

Send the PDF to @vustbot and decide which job you need. Ask for an overview when you need the whole shape of the document. Ask one specific question when you need one fact, and ask for the passage the answer comes from.

A worked example: one claim, checked against its passage

This is an illustrative exchange about a made-up vendor contract.

Your question: "Can we cancel before the end of the first year, and what does it cost?"

The answer: "Yes. Early cancellation is allowed with 60 days' written notice. The fee is three months of service charges."

The passage behind it: "Either party may terminate this Agreement prior to the end of the Initial Term upon sixty (60) days written notice, subject to an early termination fee equal to three (3) months of Service Fees."

Now you can check the answer yourself in ten seconds. The notice period matches. The fee matches. And you notice something the short answer did not say: the clause says "either party", so the vendor can cancel early too. That is worth raising before you sign.

Check the answer against the source, every time

  • Find the passage in the PDF. Search the document for a distinctive phrase from the quoted passage.
  • Compare numbers word for word. "Three months" and "three months of service charges" can be different amounts.
  • Read one paragraph before and after. Exceptions often sit right next to the rule.

When the PDF is a scan

A scanned PDF is a picture of text. If an answer seems to ignore a section you can see on the page, the text of that section may not have come through. Ask about that section directly, or send a cleaner copy of those pages. Check coverage by section, not by page count.

Open @vustbot, send the PDF, and ask the one question your decision depends on.

    vust's Summary tool handles long PDFs (up to 50 pages) and long pasted text and returns a structured summary.

  2. 02

    Read the structured brief

    You get sections and key points, not a wall of text — built for understanding, not just a TL;DR.

  3. 03

    Ask follow-up questions

    Continue in @vustbot chat to dig into specific parts of the document in plain language.

  4. 04

    Cross-check what matters

    For risk or contract calls, run the Council of Sages so a single model's read doesn't go unchecked.

Quality & trust

What you get

Structured summaries, not just chat Q&A

vust returns a structured summary of a long document — sections and key points — rather than only a chat box over a file.

Long, but bounded

PDF handling currently covers up to 50 pages per document; very long inputs get a truncation notice, so you always know what was and wasn't included.

One document per question

Each question works on the document you uploaded. Upload the PDF you need, then ask about it.

Verify the high-stakes parts

For legal or financial documents, treat any AI summary as a first pass and verify the consequential clauses yourself — or cross-check them with the Council.

FAQ

Frequently asked questions

Can it analyze a long PDF?

Yes. vust's Summary tool handles long PDFs (up to 50 pages) and long pasted text, returning a structured summary — sections and key points, not just a one-line TL;DR. You can then ask follow-up questions about the document in chat.

Can it answer one question across several PDFs at once?

No — analysis is per document: you summarize and question one document at a time. Asking a single question across a whole shelf of PDFs is a different product shape, and we would rather say so than imply it.

Does it give clickable paragraph-level citations?

No. You get a structured summary you can verify against the source, but not clickable paragraph-level source links. For anything high-stakes, check the original passage yourself.

How long a document can it handle?

PDF handling currently covers up to 50 pages per document, and very long inputs get a truncation notice so you always know what was included. For extremely long material, summarize in parts.

Is it safe to use for legal or financial documents?

Treat any AI summary as a first pass, not a verdict. It's useful for understanding and spotting where to look, but verify the consequential clauses yourself — or cross-check them with the Council of Sages.

Can I ask questions about the document?

Yes — after the summary you continue in @vustbot chat to dig into specific parts of the document in plain language.

Can vust run a systematic-review or PRISMA screening workflow?

No. vust analyzes a document you provide; it does not search a scholarly corpus, deduplicate a paper set, or run inclusion/exclusion screening. Use a dedicated review platform for that workflow, then use vust only on individual papers you are permitted to process.
