Guru vs Zettlr
A side-by-side editorial comparison of Guru and Zettlr — release velocity, themes, recent moves, and the top alternatives to consider.
Guru vs Zettlr: at a glance
What is Guru?
Guru's Knowledge Agents get the plumbing that makes their answers checkable and safe.
Guru's late-October releases all serve the Knowledge Agent. Agents can now return the records behind an analytical answer, read SCIM-provisioned profile attributes such as department and manager, and choose from sources admins can rename. On the governance side, DLP masking now covers what users type before it is logged or sent to the LLM, and each agent gets its own chat retention window of 1 to 90 days.
What is Zettlr?
Zettlr added admonitions after six years, then spent a release fixing its updater.
Zettlr 4.8.0 brought admonitions, a feature six years in the making, plus translation updates and a fix for a long-standing logic bug in search. 4.9.0 followed in late October to stop a false 'Update failed' error introduced by 4.8, drop macOS 12 and old Ubuntu support, distrust the eMudhra TLS certificates and render reference-style images.
Guru vs Zettlr: editorial side-by-side
Guru
5.0COLLAB
Guru's Knowledge Agents get the plumbing that makes their answers checkable and safe.
◆ Current state
Guru's late-October releases all serve the Knowledge Agent. Agents can now return the records behind an analytical answer, read SCIM-provisioned profile attributes such as department and manager, and choose from sources admins can rename. On the governance side, DLP masking now covers what users type before it is logged or sent to the LLM, and each agent gets its own chat retention window of 1 to 90 days.
◆ Where it's heading
The arc runs from giving agents write access to making them auditable. Mid-October brought a rebuilt Teams app with AI answers, MCP image uploads into card drafts and answer editing for skills-based agents; late October shifted to data controls and to answers that show their workings. Guru is treating the agent as the main interface and the card base as what it works on.
◆ Prediction
Expect the stated Mermaid gap in Slack, email and exports to close, and more per-agent settings in the Guardrails section where retention now sits.
Zettlr
2.5COLLAB
Zettlr added admonitions after six years, then spent a release fixing its updater.
◆ Current state
Zettlr 4.8.0 brought admonitions, a feature six years in the making, plus translation updates and a fix for a long-standing logic bug in search. 4.9.0 followed in late October to stop a false 'Update failed' error introduced by 4.8, drop macOS 12 and old Ubuntu support, distrust the eMudhra TLS certificates and render reference-style images.
◆ Where it's heading
Releases arrive roughly monthly and alternate between a headline writing feature and cleanup of the previous one. The app is tracking Electron's platform support, so older operating systems will keep falling away.
◆ Prediction
A small 4.9.x fix release or a feature-led 4.10 in about a month fits the pattern; the entries don't hint at its contents.
