Mattermost vs Trilium Notes: 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 Trilium Notes?
Trilium 0.107 turns a text note into blocks you can embed, quote and link
Trilium 0.107 rebuilds the text editor around blocks: notes can embed other notes and edit them in place, quote live excerpts that sync back to the source, and link to a single paragraph. Tables gain merged cells and sorting, the AI chat now asks before any tool reads or changes a note, and a ChatGPT Codex subscription can replace an API key. The sync protocol moves from 39 to 41, so server and every client must update together.

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.
Trilium Notes

Trilium 0.107 turns a text note into blocks you can embed, quote and link
◆ Current state
Trilium 0.107 rebuilds the text editor around blocks: notes can embed other notes and edit them in place, quote live excerpts that sync back to the source, and link to a single paragraph. Tables gain merged cells and sorting, the AI chat now asks before any tool reads or changes a note, and a ChatGPT Codex subscription can replace an API key. The sync protocol moves from 39 to 41, so server and every client must update together.
◆ Where it's heading
After 0.105 made backups restorable and 0.106 rebuilt the kanban board, Trilium is now reworking its core unit, the text note, toward a block-based model with cross-note reuse. The AI layer is being made safe for a real database through approval prompts and cheaper through subscriptions rather than per-token keys.
◆ Prediction
Expect 0.107.x patches fixing block-editor and sync regressions, and the web clipper 1.2 release that was waiting on 0.107.
