SiYuan vs Slack
Side-by-side trajectory, velocity, and editorial themes.
SiYuan rides its 3.7 overhaul with rapid alpha polish on mobile and cross-platform
SiYuan is an open-source, local-first knowledge base. Its 3.7 line was a throughout renewal — a redesigned UI, a kernel plugin system, and a CLI — and the feed since has been a fast cadence of alpha releases (3.7.1, 3.7.2) grinding on mobile editing and cross-platform quirks across Android, HarmonyOS, iOS, and the Microsoft Store build.
The work is consolidating the 3.7 overhaul along three lines: extensibility (kernel plugins), cross-platform parity (HarmonyOS now treated as a first-class target alongside Android and iOS), and mobile editing polish. The 'step toward intelligence' language hints at AI features, but the concrete shipping is platform breadth and extensibility.
Expect 3.7.2 to stabilize out of alpha with continued mobile and HarmonyOS fixes; the kernel plugin system points toward a growing third-party plugin ecosystem as the next surface.
Slack is quietly rebuilding itself as a runtime for third-party agents.
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.
Each release fills in a piece of an agent platform — context in, tools out, and a native place for agents to converse. Block Kit is gaining richer primitives (containers, data visualization) that read as the display layer for agent output. Three CLI releases in a month show the tooling keeping pace with the expanding surface.
Expect the next moves to connect these pieces: agent context feeding MCP tool calls, and Block Kit's new blocks becoming the standard way agents render results in-channel.
