What is Reflect?
Reflect's quiet SQLite frontend rewrite reset its performance ceiling and unblocked the AI roadmap.
Reflect is a personal note-taking app with embedded AI features (chat, transcription, summarization). The structurally important move of the year was a frontend rewrite onto SQLite, shipped across iOS, web, macOS, and then iPad over March 2025 — fixing the load-time and large-collection ceilings that had been quietly limiting the product. The rest of the visible cadence has been AI surface work: in-line voice transcription, Gemini for long-context chat, AI link summaries that feed semantic search, and an editor for custom prompt templates.
What is SiYuan?
SiYuan is adding mind map block types and calendar scheduling depth as it pushes toward 3.8.6.
SiYuan is a local-first personal knowledge management tool in rapid alpha/beta iteration. The 3.8.6 alpha cycle introduces dedicated mind map and mind map item block types as first-class primitives, expanded calendar views with ISO week numbers and inbox scheduling, JavaScript embed support in image and PDF exports, and workspace storage statistics. The product ships multiple alpha builds per day and is clearly in a feature-accumulation phase before a stable release.

Reflect's quiet SQLite frontend rewrite reset its performance ceiling and unblocked the AI roadmap.
◆ Current state
Reflect is a personal note-taking app with embedded AI features (chat, transcription, summarization). The structurally important move of the year was a frontend rewrite onto SQLite, shipped across iOS, web, macOS, and then iPad over March 2025 — fixing the load-time and large-collection ceilings that had been quietly limiting the product. The rest of the visible cadence has been AI surface work: in-line voice transcription, Gemini for long-context chat, AI link summaries that feed semantic search, and an editor for custom prompt templates.
◆ Where it's heading
Reflect is closing the desktop-mobile parity gap one feature at a time (advanced search filters made the jump from desktop to iOS in August) while making the AI surface more configurable and more entangled with search. The team's own July release explicitly named AI chat on mobile as the next milestone. The pattern: ship the architectural foundation, then layer the AI features that depend on it.
◆ Prediction
AI chat on mobile is the next named milestone from the team's own published roadmap notes. Beyond that, expect more features that quietly feed AI-generated context into search (the link-summary pattern extended to OCR'd PDFs, voice transcripts, etc.) and continued performance work that exploits the SQLite rewrite.

6.3COLLAB
SiYuan is adding mind map block types and calendar scheduling depth as it pushes toward 3.8.6.
◆ Current state
SiYuan is a local-first personal knowledge management tool in rapid alpha/beta iteration. The 3.8.6 alpha cycle introduces dedicated mind map and mind map item block types as first-class primitives, expanded calendar views with ISO week numbers and inbox scheduling, JavaScript embed support in image and PDF exports, and workspace storage statistics. The product ships multiple alpha builds per day and is clearly in a feature-accumulation phase before a stable release.
◆ Where it's heading
SiYuan continues deepening its block-based model by adding new primitive types — mind maps are the latest addition to a growing set that already includes databases, calendars, and embed blocks. Each new primitive adds interoperability complexity; the concurrent improvements to backlink display, reference sorting, and transitive link traversal suggest an underlying effort to make cross-block navigation coherent as the graph grows. The AI agent is also receiving model integrations (TypeSafe System One for decision modeling).
◆ Prediction
The 3.8.5 and 3.8.6 lines will merge into a stable release soon. The AI agent model integration and decision-model support suggest a near-term push to make the AI layer genuinely useful for structured knowledge work, not just Q&A over notes.
