A side-by-side editorial comparison of Mattermost and Tella — release velocity, themes, recent moves, and the top alternatives to consider.
Mattermost vs Tella: at a glance
What is Mattermost?
Mattermost v12 puts user-scoped permissions, private models and audit trails on every agent action.
Mattermost's feed spent five weeks on security and resilience essays; the last product release was v11.11's data-spillage exposure report. v12 changes that: agents now act with the requesting user's access rather than a shared service account, can run on private models, and leave an audit trail per action. The announcement is short on detail, but the pitch is clear and aimed at defense and regulated buyers.
What is Tella?
Tella adds a Free plan, redesigns the editor, and broadens distribution into Intercom and beyond.
Tella is in a sustained editor-polish-plus-distribution cycle. The big change: a Free plan now sits alongside Pro, paired with an in-product AI support assistant. The editor was redesigned with a left-side toolbar, lighter UI, and a new transcript sidebar. New layouts (50/50 split) and finer camera-bubble positioning (3×3 grid plus three sizes across orientations) give creators more compositional control. Distribution widens with an Intercom Help Center integration and a refreshed tella.com.

Mattermost
6.3COLLAB
Mattermost v12 puts user-scoped permissions, private models and audit trails on every agent action.
◆ Current state
Mattermost's feed spent five weeks on security and resilience essays; the last product release was v11.11's data-spillage exposure report. v12 changes that: agents now act with the requesting user's access rather than a shared service account, can run on private models, and leave an audit trail per action. The announcement is short on detail, but the pitch is clear and aimed at defense and regulated buyers.
◆ Where it's heading
The essays on zero trust, data spillage and out-of-band response were building toward this. Mattermost is positioning its AI agents as governed, mission-safe tools inside its classified-environment niche rather than competing on agent breadth. The in-house Matty Code agent shows it also uses agents to build the product itself.
◆ Prediction
Expect v12.x follow-ups that publish admin controls and audit-log detail for agent actions, plus more deployment-focused content aimed at defense buyers.
Tella
6.3COLLABMEETINGS
Tella adds a Free plan, redesigns the editor, and broadens distribution into Intercom and beyond.
◆ Current state
Tella is in a sustained editor-polish-plus-distribution cycle. The big change: a Free plan now sits alongside Pro, paired with an in-product AI support assistant. The editor was redesigned with a left-side toolbar, lighter UI, and a new transcript sidebar. New layouts (50/50 split) and finer camera-bubble positioning (3×3 grid plus three sizes across orientations) give creators more compositional control. Distribution widens with an Intercom Help Center integration and a refreshed tella.com.
◆ Where it's heading
The product is leaning into accessible-funnel-plus-creative-control: lower the barrier to start (Free plan), make the editor look modern and inviting, and embed videos where customers already are (Intercom). View notification controls and webhook events for viewer activity hint at an upcoming push toward integration-ready video analytics.
◆ Prediction
Expect more distribution surfaces (Slack, Notion-style embeds beyond Intercom) and AI features beyond the support assistant — likely auto-chapters, B-roll generation, or transcript-driven editing. The Free plan likely drives an experimentation phase before the next pricing/packaging tightening.
