Common questions
Does it work behind paywalls?

Will it preserve quotes and citations?
Yes. Summio extracts pull quotes verbatim and links every claim back to its passage in the source.

You pick — short, medium, long, or detailed. A 25-minute longread compresses to ~4 minutes at short depth, ~10 minutes at detailed.
