About Grain
Grain learns voices, so in-person and shared-mic meetings finally get reliable speaker labels.
Voice Signatures let Grain recognise speakers by voice rather than by audio channel, so transcripts label who said what even when several people share one mic or a capture comes from an unknown source. It ships alongside an upgraded transcription model, a split between workspace and account settings, fewer false positives from trackers, and a cleaner permission screen on shared meeting links. July's release put Grain inside ChatGPT and added MCP tools.
