DOCUMENT GUIDE

Ask questions about your PDF

Source search finds matching original passages. Optional AI answers use the supplied document and your question; they do not browse the web or verify claims independently. An answer can be incomplete or wrong even when it cites a page.

  1. Upload a supported document within the file and page limits.
  2. Enter a specific question. Choose source search or AI answer; AI requires provider consent.
  3. Inspect the cited pages and download or edit the answer. Keep the original for comparison.

Free access and limits

No account or payment. One document up to 4 MB, 10 PDF pages and 60,000 extracted characters. Original source tools run on our server without a generative model.

Optional AI summaries and questions use the configured provider displayed before processing. Free AI accepts up to 32,000 UTF-8 source bytes and 3 requests per network per UTC day, subject to a shared site budget and availability. Shared networks share an allowance.

Before AI processing, you must consent to send extracted text and your question to the provider. AI results and OCR can contain errors.
