Three steps. No setup.
Most tools ask you to organize a library, sign up, pick a plan. We ask you to drop a file.
Upload
Drop in a PDF or a whole folder. Scanned, encrypted, or 500 pages long — we handle it. Text extraction runs automatically.
Ask
Chat in plain language. Every answer is grounded in the document and footnoted to the exact page.
Export
Send the chat to Markdown, Word, or Notion. Share a read-only link. Pin to a folder for next time.
See your PDF and the answer in the same view.
PDF on the left, chat on the right, citations linking the two. Click a footnote — the page scrolls and the source paragraph lights up.
