Slack is quietly rebuilding itself as a runtime for third-party agents.
A side-by-side editorial comparison of SiYuan and Powell Software — release velocity, themes, recent moves, and the top alternatives to consider.
SiYuan's v3.7.0 turns a local-first note editor into an extensible, AI-native knowledge platform
SiYuan is a local-first, block-based notes and knowledge tool shipping at a rapid open-source cadence. It has just closed out the v3.7.0 cycle, a landmark release, through a long chain of beta and rc builds, and is already iterating on v3.7.1 alphas. The tracked feed is dominated by that single release train.
Powell's feed is mostly content marketing, punctuated by occasional 'What's new' release digests.
Powell Software's tracked feed is dominated by content marketing — digital-workplace guides, event recaps, and lead-gen tools — around its Microsoft 365 intranet product. The one product signal in the mix is a periodic 'What's new in Powell' release digest; the latest bundles a mobile-first experience, AI additions, and richer analytics.

The tracked feed is dominated by that single release train.
The direction is clear from v3.7.0: SiYuan is becoming an extensible, AI-native knowledge platform. It added a kernel plugin system, a scripting CLI, and an AI knowledge base (SiYuan Agent plus vector search) in public testing, on top of continuous editor, database, and mobile refinement. The v3.7.1 alphas point to a stabilization phase, tightening databases, mobile, and platform edge cases.
Expect the v3.7.1 line to stabilize the 3.7.0 features, hardening the plugin system, CLI, and AI knowledge base, and to move the AI Agent and vector search from public testing toward general availability.

The one product signal in the mix is a periodic 'What's new in Powell' release digest; the latest bundles a mobile-first experience, AI additions, and richer analytics.
To the extent the feed shows product direction, it points at mobile-first intranet access, embedded AI, and storytelling analytics — the standard digital-workplace playbook. But most entries are marketing collateral, so cadence is hard to read from this source; the 'What's new' posts are the only reliable release signal.
The next genuine product signal will likely arrive as another 'What's new in Powell' digest continuing the mobile, AI, and analytics themes; the rest of the feed stays blog content.
