Frequently asked questions

Yes. The web tool is free and needs no account: upload a PDF, get a summary, key points, answers or the extracted text. Fair-use limits apply per network (about 12 PDFs per hour). Paid plans exist only for the API.

Up to 300 pages and 20 MB. Long documents are split into parts that are each analysed, then merged into one summary, so the middle of the document is not skipped. Scanned PDFs are read with OCR (first 40 pages on the free tool).

Yes. When a page has no text layer, OCR runs automatically (English, French, German, Spanish, Italian and Portuguese are recognised best). Image quality matters: a clean 300 dpi scan works much better than a tilted phone photo.

Yes — open the “Ask questions” tab. Answers are based only on the document and cite the page, like (p. 12), so you can verify them. If the answer is not in the PDF, the assistant says so instead of guessing.

The document can be in any common language. The summary is written in the language of the PDF by default, or in any of 20 output languages — handy to summarize an English report in Spanish or a German contract in English.

The PDF is deleted right after its text is extracted. The text is kept for 60 minutes to let you ask follow-up questions, then deleted. Nothing is used to train AI models. Details in our privacy policy.

The model is instructed to use only what the document says and to cite pages, which keeps answers checkable. AI can still misread tables, figures or ambiguous wording — for contracts, medical or financial decisions, verify the cited pages before relying on a point.

Yes. Send a PDF as multipart/form-data to the REST endpoint and receive the summary as JSON or as a stream. The free plan includes 250 requests per month. See the API documentation.

Not directly. Open the file with its password and use “Print → Save as PDF” to create an unprotected copy, then upload that copy.

Students revising courses, researchers screening papers, lawyers and buyers reviewing contracts, analysts reading annual reports, and anyone who receives long PDFs and needs the substance quickly. Developers use the API to add summaries to their own apps.

No. Sign up with an email and you get an API key on the free plan straight away.

One API call that returns a summary for one PDF counts as one request, whatever its length within your plan’s page limit.

Yes. Subscriptions are monthly and can be cancelled from your dashboard; you keep access until the end of the paid period.

Cards through Stripe. Invoices are available in your dashboard.
