Scored by a Toolio reviewer after real useOur verdict
Spacegrapher does three things in sequence: pulls down the audio from a Twitter Space, converts it to text, and condenses that transcript into a summary. It's aimed at people who want the gist of a long Space discussion without listening live or scrubbing through a recording. It only works with Twitter Spaces audio, offers in-app purchases beyond the free version, and has no ratings yet to vouch for accuracy.
