Mattermost v11.11 adds data spillage exposure tracking as v12.0 breaking changes loom
A side-by-side editorial comparison of Guru and Tana — release velocity, themes, recent moves, and the top alternatives to consider.
Guru is tightening the leash on the Knowledge Agent it just handed the keys to.
Everything recent is the Knowledge Agent. It already writes to the knowledge base — creating collections, bulk-archiving cards, running drafts through to publish — and the newest work narrows where and how it acts: per-channel behaviour in Slack, and skills pinned to a named document instead of searching for one. Around that sit guardrails, skill permissions, recoverable drafts and scheduled automations.
Tana races toward ambient AI assistant — voice commands now execute silently without interrupting you
Tana has shipped three major voice and agent capabilities in quick succession: a multitasking background agent that handles multiple requests simultaneously while you are in a meeting, auto-detection of unscheduled external meetings, and most recently a Hey Tana trigger that silently executes commands without entering a voice session at all. A native Calendar view also landed in the same release. The product has moved far past note-taking into ambient meeting assistant territory.

Around that sit guardrails, skill permissions, recoverable drafts and scheduled automations.
The arc is autonomy first, then control. Having given the agent write access and a schedule, Guru is now spending releases on determinism and scoping — making the agent's behaviour predictable per channel and its grounding exact per skill. That is the work required before customers let an agent run unsupervised on a knowledge base, and it suggests trust, not answer quality, is the constraint being engineered against.
The scoping controls point toward auditability as the next gap: some record of what the agent did to the knowledge base, and per-skill or per-channel review of those actions, to match the permissions and guardrails already shipped.

Every recent release adds ambient presence — Tana wants to run in the background of your workday, not only when you choose to open it. The combination of silent command execution, meeting capture, and calendar integration points toward a product that acts as a persistent AI colleague rather than a structured note-taking tool.
Tighter integration between calendar events and AI briefs is the likely next move, along with expansion of which external tools the background agent can act in. Whether Tana can hold the ambient-assistant position depends on how reliably the background execution performs across different meeting platforms.
