The problem
Long PDFs cost you hours. Skimming costs you more.
The clause on page 37. The number in a footnote. The caveat in the appendix. That is where the risk lives, and that is exactly what skimming misses.
Reading it yourself
about 2 hours
A 60-page agreement runs to roughly 30,000 words. At an average reading pace, that is two hours before you even start taking notes.

Six expert lenses
Contracts, research papers, financial reports, study notes, meeting packs, or a smart general brief.
Ask anything
Follow-up questions get direct answers with page references. When the PDF does not say, neither do we.
Numbers and deadlines, pulled out
Amounts, percentages, dates and notice periods, gathered in one place so nothing slips past you.
Private by design
Your PDF is read in your browser. We never store your documents or briefs, and they are never used to train AI models.
Any language in, 15 out
Brief a German contract in English or an English paper in Spanish, Japanese or Arabic.
Scanned PDFs too
Scans and photographed pages are read visually, so old contracts and receipts work as well.
Copy or download
Paste your brief into an email or a ticket, or save it as a Markdown file for your notes.
Built for long documents
Up to 100 pages free, and every brief tells you exactly which pages it covers.

FAQ
Good questions. Straight answers.
Anything else on your mind? The quickest answer is to drop in a PDF and see for yourself. It is free.
How accurate are the summaries?
Every point in your brief is tagged with the page it came from, so you can check anything in one click. The AI is instructed to use only what the document says and to tell you when something is not covered. It can still make mistakes, so check anything important against the highlighted passage.
Is my document private?
Your PDF is opened in your browser. To write the brief, only the text of the document is sent over an encrypted connection to our AI provider, or the file itself if it is a scan. We never store your documents or briefs, and they are not used to train AI models.
What kinds of PDFs work?
Contracts, leases, NDAs, research papers, theses, annual reports, earnings releases, textbooks, lecture notes, board packs, RFPs, manuals and policies. Text-based PDFs work best, and scanned PDFs up to 10 MB are read visually.
How long can a PDF be?
On the free plan, up to 100 pages per PDF and files up to 50 MB. For longer documents, the brief covers the first 100 pages and says so clearly. Pro will handle documents up to 1,000 pages.
What is a lens?
A lens tells the AI how to read your document. The contract lens looks for obligations, money, deadlines and risky clauses. The research lens covers the question, the method, the findings and the limitations. If you do not pick one, we choose the best fit for you.
Can I ask follow-up questions?
Yes. Ask anything about the document and get a direct answer with page references. If the PDF does not answer your question, it says so instead of guessing.
Which languages are supported?
You can upload PDFs in most languages and get your brief in English, Spanish, French, German, Portuguese, Italian, Dutch, Polish, Turkish, Arabic, Hindi, Indonesian, Japanese, Korean or Simplified Chinese.
Do I need an account?
No. You can brief 3 PDFs and ask 25 questions every day for free, without signing up.
When is Pro available, and what is founder pricing?
Pro is opening soon. Reserve a spot now and you keep the launch price for as long as you stay subscribed. No card is needed to reserve, and we will email you once when it is ready.
Can I rely on a brief for legal, financial or medical decisions?
Use it to understand a document faster and to find what to check, not as professional advice. For decisions that matter, read the cited pages and speak to a qualified professional.
