Tana vs SiYuan: at a glance
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.
What is SiYuan?
SiYuan keeps grinding on its database engine, flashcards, and cross-platform reach
SiYuan is a local-first, block-based knowledge base — self-hostable, privacy-oriented, and increasingly a Notion-style database tool as much as an editor. The current cycle pours effort into the database layer (relations, rollups, deep links, column alignment, templates), spaced-repetition flashcards (now buildable from callouts and blockquotes), and broad platform parity across iOS, Android, HarmonyOS, and tablets.

◆ 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.
SiYuan
6.3COLLAB
SiYuan keeps grinding on its database engine, flashcards, and cross-platform reach
◆ Current state
SiYuan is a local-first, block-based knowledge base — self-hostable, privacy-oriented, and increasingly a Notion-style database tool as much as an editor. The current cycle pours effort into the database layer (relations, rollups, deep links, column alignment, templates), spaced-repetition flashcards (now buildable from callouts and blockquotes), and broad platform parity across iOS, Android, HarmonyOS, and tablets.
◆ Where it's heading
The product ships on a fast alpha/beta/stable train, with each stable (v3.7.2, v3.7.3) consolidating dozens of small enhancements plus routine security fixes. Direction is steady rather than pivoting: deepen the database toward Notion parity, harden mobile/HarmonyOS input, and expand flashcards — with AI touched only lightly (provider/model config tweaks, an AI edit window).
◆ Prediction
Expect a v3.7.4 stable that folds in the current alpha's automatic heading numbering, expanded flashcard sources, and precise database relation filters. Continued HarmonyOS and mobile-input polish is the safe bet; no larger architectural or AI shift is visible in these entries.
