1. Add one source without signing up.
2. Ask a question about its contents.
3. Review the answer against the source. Delete the source when you finish.

## Example inputs

- Your question: Summarise the key facts and reference the source.

## Limits and what to check

PDFs must be at most 2 MB and 50 pages, with no more than 250,000 extracted characters. Scanned PDFs are unsupported. Answers are drafts, and page numbers or quotations must be checked against the original.

## Frequently asked questions

### Which PDFs can I chat with?

Text-based PDFs of up to 2 MB and 50 pages. Scanned or image-only PDFs have no readable text and are not supported.

### Can it give me page numbers?

No. Page numbers are not reliably available from extracted text, so answers quote short passages instead of citing pages.

### What happens with a very long PDF?

If the text is longer than the context limit, only an opening excerpt is used and you are told. Ask about later sections in a shorter file.

### When is my PDF deleted?

After one hour without an accepted question, or straight away when you choose Start over. No account is needed.
