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 Rocket.Chat?

Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.

The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.

Grain vs Rocket.Chat: editorial side-by-side

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.

Rocket.Chat logo6.3

Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.

◆ Current state

The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.

◆ Where it's heading

9.0 is in stabilization: each candidate is smaller than the last, and the load fixes are being carried to the LTS line rather than held for the major. Native LiveKit video is being promoted step by step, from alpha to beta and now as the named default provider option.

◆ Prediction

With rc.7 down to a handful of fixes, 9.0.0 GA is the next likely release, followed by further 8.9.x LTS patches carrying the same fixes.
