Grain adds consent controls and rule-based privacy as its meeting data reaches more AI tools.
Grain's October release lets workspaces flag meetings as sensitive by rule and skip auto-sharing them, adds recording consent controls, and brings back a mobile beta. It follows August's Voice Signatures, which label speakers by voice so shared-mic and in-person captures attribute correctly. Earlier in the year Grain shipped an MCP server and a ChatGPT integration.
Krisp moves call transcripts and live captions to cloud transcription in KrispCX 2.84.4.
Krisp sells a Call Center AI suite to BPOs and contact centers: Accent Conversion, Voice Translation, QA scoring, deepfake and fraud detection. KrispCX 2.84.4 adds cloud transcription in beta for more accurate transcripts and Live Captions, plus in-call hints when the Krisp microphone is in use; the source note is truncated. October brought Conference mode for Voice Translation and a Fraud Detection beta.

Grain spent the first half of 2026 exposing meeting data to AI assistants, and is now adding the governance that wider exposure needs: consent, sensitivity rules and controlled sharing. Release cadence has slowed to roughly one announcement every month or two.
Further admin and privacy controls around what AI tools can read are the likely next step; the entries do not show a timeline for the mobile app leaving beta.

Releases arrive on a two-week cadence and keep stacking agent-assist features on the live call, from translation to fraud signals to captions. The September move to free-to-try has been followed by incremental depth rather than new product lines.
Expect more of the live-call layer to move to cloud processing, with QA scoring and translation likely reusing the new transcription. The truncated notes leave the scope of the cloud beta unclear.
