2. Ask a question about its contents.
3. Review the answer against the source. Delete the source when you finish.

## Limits and what to check

Only extracted text is available to the model. It may miss layout, charts or relationships between table cells. Verify answers in the original document before acting on them.

## Frequently asked questions

Text-based PDF, DOCX, TXT, Markdown or CSV files of up to 2 MB. Scanned PDFs have no readable text and are not supported.

### Do answers quote the document?

The AI model is instructed to quote short exact excerpts with the source title, so you can find the passage and check it.

No. Add a file and ask questions without signing up. Human verification and a limited number of free questions apply.

### How long does my uploaded document stay available?

It is deleted after one hour without an accepted question, and each accepted question restarts that hour. Start over deletes it at once.
