SpaceGrapher

SpaceGrapher installs as a Chrome extension and adds a workflow around X (formerly Twitter) Spaces, the platform's live audio rooms. From inside the browser it can pull down the audio of a Space, run that audio through a speech-to-text step and then condense the resulting transcript into a short summary, so that a live conversation becomes something you can skim, search or archive afterwards.

The extension is intentionally minimal: the Chrome Web Store listing reports version 0.0.1, an install size of under 9 KB and a small user base, with the listing last updated in September 2023. It offers in-app purchases, which is how any paid transcription or summarisation capacity is likely unlocked, although exact credit limits and prices are not published on the store page itself.

It is a good fit for podcast-style Spaces, AMA sessions, community calls and research interviews hosted on X, where a downloadable audio file plus a written summary saves a lot of manual work. Because it is an independent, unaffiliated tool built against a platform that changes its internals frequently, features can break after X ships updates, and users should expect to treat it as a convenience utility rather than a guaranteed archive of record.
