Memos vs SiYuan: at a glance
What is Memos?
Memos is turning a personal note store into an agent-addressable, private-by-default service
The release candidates in this window carry unusually heavy changes for a self-hosted note app: an embedded MCP endpoint exposing memo CRUD, comments, attachments and tags to AI clients; live updates over server-sent events; revocable share links; and a browser Web Clipper for saving pages and selections as Markdown. A parallel candidate makes instances without an explicit instance URL run in private mode and rewrites filters onto CEL timestamps.
What is SiYuan?
A relentless release grind hardening databases and cross-platform editing, no single pivot in sight
SiYuan is deep in its 3.7.x cycle, shipping alpha, beta, and stable builds within days of each other. The work concentrates on two fronts: maturing its inline database feature (relation backlinks, column alignment, deep links, item templates) and grinding down cross-platform rough edges across iOS, iPad, Android, and HarmonyOS. This is a local-first notes tool being polished, not redirected.

Memos is turning a personal note store into an agent-addressable, private-by-default service
◆ Current state
The release candidates in this window carry unusually heavy changes for a self-hosted note app: an embedded MCP endpoint exposing memo CRUD, comments, attachments and tags to AI clients; live updates over server-sent events; revocable share links; and a browser Web Clipper for saving pages and selections as Markdown. A parallel candidate makes instances without an explicit instance URL run in private mode and rewrites filters onto CEL timestamps.
◆ Where it's heading
Two directions are converging. One is machine access — MCP moved from a stateful server with prompts and resources to a stateless, tools-only endpoint generated from the OpenAPI schema, which is a deliberate narrowing toward something agents can call reliably. The other is defaults that assume the instance is private until an admin says otherwise. Together they reposition Memos from a personal web app to a small API-shaped service with a human UI on top.
◆ Prediction
Expect the MCP surface to stabilise against the OpenAPI schema as the source of truth and the private-by-default posture to carry into a general release, with clients that relied on prompts, resources or unprefixed tool names needing to migrate.

A relentless release grind hardening databases and cross-platform editing, no single pivot in sight
◆ Current state
SiYuan is deep in its 3.7.x cycle, shipping alpha, beta, and stable builds within days of each other. The work concentrates on two fronts: maturing its inline database feature (relation backlinks, column alignment, deep links, item templates) and grinding down cross-platform rough edges across iOS, iPad, Android, and HarmonyOS. This is a local-first notes tool being polished, not redirected.
◆ Where it's heading
The database layer is becoming SiYuan's center of gravity — each release adds another Notion-style capability (templates, deep links, backlinks in the attribute panel) rather than editor primitives. In parallel, mobile and HarmonyOS parity keeps eating release notes, suggesting the team is chasing feature symmetry across an unusually wide platform spread. Expect the database to keep accreting relational features until it rivals a light structured-data workspace.
◆ Prediction
The next stable (v3.7.4) will likely consolidate the current alpha database and export fixes without a headline feature; a larger database or AI-editing push is the more probable place a genuine direction change would surface.
