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 stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0

SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

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.

SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0

◆ Current state

SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

◆ Where it's heading

This is consolidation of the surface 3.8.0 opened, not an extension of it. The agent, semantic search and MCP endpoint arrived in the 3.8.0 line; 3.8.1 makes them portable and pluggable - skills come from a directory the user controls, editor actions follow the user between devices, and the provider layer now speaks the OpenAI Responses API rather than one bespoke shape. The high beta count against a modest final diff shows a project stabilising a young subsystem rather than building a new one.

◆ Prediction

The next line most likely pushes on the skills directory - discovery, sharing or marketplace distribution of user-level skills - since that is the piece 3.8.1 made user-editable without giving it a distribution path.
