Mattermost vs Tana: at a glance
What is Mattermost?
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
What is Tana?
Tana now records meetings around one laptop and adds Lovable and Ari as agents.
Tana has turned into a meeting workspace: a meeting-timeline Home, live suggestions that draft tasks for approval, research briefs and an iPhone app. October 26 let users bring their own Claude or ChatGPT into calls. The November 12 release captures in-person and hybrid meetings, splits several voices on one microphone into separate speakers, lets users name transcript speakers, and adds Lovable and cfo.ai's Ari as external agents that answer privately inside meetings.

Mattermost
6.3COLLAB
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
◆ Current state
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
◆ Where it's heading
Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.
◆ Prediction
Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.
Tana
5.0COLLAB
Tana now records meetings around one laptop and adds Lovable and Ari as agents.
◆ Current state
Tana has turned into a meeting workspace: a meeting-timeline Home, live suggestions that draft tasks for approval, research briefs and an iPhone app. October 26 let users bring their own Claude or ChatGPT into calls. The November 12 release captures in-person and hybrid meetings, splits several voices on one microphone into separate speakers, lets users name transcript speakers, and adds Lovable and cfo.ai's Ari as external agents that answer privately inside meetings.
◆ Where it's heading
Tana is covering every kind of meeting, including the ones where people share a room, and opening its meeting surface to more outside agents. Enterprise admins can now choose which external agents members may use, the governance step that usually precedes a wider agent catalog.
◆ Prediction
Expect more external agents added to the Settings list and agent actions tracked in Work's Waiting on you, as the November release began with status rows for accepted actions.
