AFFiNE vs Guru
A side-by-side editorial comparison of AFFiNE and Guru — release velocity, themes, recent moves, and the top alternatives to consider.
AFFiNE vs Guru: at a glance
What is AFFiNE?
AFFiNE ships from a canary firehose — invitations, iOS sharing, and self-host fixes.
Releases land almost daily as dated canary tags, each carrying a single merged pull request with a CodeRabbit-generated summary. The recent run covers three areas: workspace onboarding, where invitation links now require sign-in and can switch accounts mid-accept; mobile capture, with an iOS share sheet that saves URLs, text, web pages, and images straight into a workspace; and self-hosting, including a Render one-click blueprint and a GitHub OAuth fix that had been breaking self-hosted login outright.
What is Guru?
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.

AFFiNE
6.3COLLAB
AFFiNE ships from a canary firehose — invitations, iOS sharing, and self-host fixes.
◆ Current state
Releases land almost daily as dated canary tags, each carrying a single merged pull request with a CodeRabbit-generated summary. The recent run covers three areas: workspace onboarding, where invitation links now require sign-in and can switch accounts mid-accept; mobile capture, with an iOS share sheet that saves URLs, text, web pages, and images straight into a workspace; and self-hosting, including a Render one-click blueprint and a GitHub OAuth fix that had been breaking self-hosted login outright.
◆ Where it's heading
Two audiences are being served in parallel. Self-hosters get deployment and authentication work — the OAuth token exchange was failing with a 403 for want of a User-Agent header, which is the kind of bug that blocks adoption entirely until someone hits it. Meanwhile the client work is about getting content into AFFiNE from outside it: the iOS share extension, HTML import that now maps hex, RGB, HSL, and named colors onto the app's themes. The pattern is a product working on capture and onboarding friction rather than new document capabilities.
◆ Prediction
Expect the canary cadence to continue at roughly one pull request per tag, with more import fidelity and mobile capture work, and further self-host deployment targets after the Render blueprint. A stable release consolidating this run is the likely next milestone.
Guru
5.0COLLAB
Guru is tightening the leash on the Knowledge Agent it just handed the keys to.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
