What is Grain?

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.

What is Signal Desktop?

Signal Desktop's 8.36 beta adds favorite sticker packs after a fix-only week.

Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.36.0-beta.1 adds favorite sticker packs, so the ones a user relies on stay at hand. It follows the fix-only v8.35.0-beta.1 and v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling.

Grain vs Signal Desktop: editorial side-by-side

G
Grain
COMMS
2.5

Grain adds consent controls and rule-based privacy as its meeting data reaches more AI tools.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

S5.0

Signal Desktop's 8.36 beta adds favorite sticker packs after a fix-only week.

◆ Current state

Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.36.0-beta.1 adds favorite sticker packs, so the ones a user relies on stay at hand. It follows the fix-only v8.35.0-beta.1 and v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling.

◆ Where it's heading

The desktop app is closing gaps with mobile one feature at a time, separated by maintenance betas. Visible features arrive about every two to three builds.

◆ Prediction

The next feature beta is likely within one or two builds, based on the cadence since October. The entries don't indicate what it will contain.
