Common questions

Are scanned PDFs supported?

Yes. Summio detects scanned image PDFs and runs OCR before summarising. Quality depends on the scan.

How private is my upload?

Documents stay inside your account. They are not used to train AI models. Delete them at any time and they are gone within 30 days.

Is there a file-size limit?

A few hundred megabytes is fine for most research papers and reports. Very long scanned books may need to be split first.
