AFFiNE vs Tana: at a glance
What is AFFiNE?
AFFiNE's daily canary grind: server GC plumbing and steadier third-party imports.
AFFiNE ships near-daily canary and beta builds off the same PR stream, so releases arrive in pairs (a canary and a 0.27.x-beta cut of the same change). The current focus is server-side garbage collection for docs and blobs — reconciling missing workspace docs, making cleanup resumable after partial runs — plus editor fixes to kanban and Obsidian import.
What is Tana?
Tana is rebuilding itself around meetings — capture, present, and AI wrap-up, all native
Tana, once a supertag-driven knowledge base, now spends nearly all its release energy on a meeting layer: a pre-meeting hub card, one-click capture of external Zoom/Teams/Meet calls through system audio, live document presentation, and AI agents that summarize and extract outcomes. The Today page has become the product's home surface, organizing the day around calls and their generated artifacts. Recent work is dense and iterative — join nudges, permission recovery, presentation palettes, voice agents — all pointed at the same target.

AFFiNE's daily canary grind: server GC plumbing and steadier third-party imports.
◆ Current state
AFFiNE ships near-daily canary and beta builds off the same PR stream, so releases arrive in pairs (a canary and a 0.27.x-beta cut of the same change). The current focus is server-side garbage collection for docs and blobs — reconciling missing workspace docs, making cleanup resumable after partial runs — plus editor fixes to kanban and Obsidian import.
◆ Where it's heading
The work is infrastructure hardening for the self-hosted server: document/blob GC with checkpointed, resumable reconciliation, dangling-reference semantics, and permission-enforced deletion. On the editor side, import fidelity (Obsidian vaults, nested attachments) is the visible-to-users thread. It's a stability-and-migration grind, not a feature expansion.
◆ Prediction
Expect the 0.27.3 beta line to consolidate the doc/blob GC work toward a stable cut, with Obsidian/import reliability continuing as the main user-facing improvement.
Tana

Tana is rebuilding itself around meetings — capture, present, and AI wrap-up, all native
◆ Current state
Tana, once a supertag-driven knowledge base, now spends nearly all its release energy on a meeting layer: a pre-meeting hub card, one-click capture of external Zoom/Teams/Meet calls through system audio, live document presentation, and AI agents that summarize and extract outcomes. The Today page has become the product's home surface, organizing the day around calls and their generated artifacts. Recent work is dense and iterative — join nudges, permission recovery, presentation palettes, voice agents — all pointed at the same target.
◆ Where it's heading
The direction is unambiguous: Tana wants to own the full arc of a meeting — before (hub, invites, calendar sync), during (capture, present, live AI digest), and after (summaries, outcomes, review queue) — and fold the results back into its typed knowledge graph. External-meeting capture moving to on-by-default and live doc presentation without screen sharing put it in direct competition with Granola and Fellow, not just as a notes tool. The knowledge-base roots are increasingly the substrate that meeting outputs land in, not the headline.
◆ Prediction
Expect the next releases to deepen the AI wrap-up loop — richer automatic outcome extraction, agent actions triggered from meeting content, and tighter linking of meeting artifacts into typed entities — since that is the recurring thread across these entries.
