SiYuan keeps grinding polish across mobile, HarmonyOS, and its database views
A side-by-side editorial comparison of Circle and Logseq — release velocity, themes, recent moves, and the top alternatives to consider.
Circle is turning its community platform into an AI-native OS, from prompt-built setups to MCP.
Circle runs the full community stack: courses, events, memberships, branded apps, and a built-in CRM. Across 2026 it has layered AI through all of it, from Copilot analytics and AI agents to Circle MCP and, now, Circle AI, which generates complete community structures from a prompt. The June Eclipse event bundled that AI layer with a redesigned course builder, a unified Inbox, the Discover 2.0 marketplace, and Circle Studios, a done-for-you service for top creators.
Logseq ships its first 2.0 beta, betting its future on a database backend.
Logseq spent over a year in a slow beta cadence on the file-based 0.10.x line, shipping mostly Electron bumps, embed fixes, and one security patch. Today it released the first public beta of 2.0, rebuilt on a new database (DB) storage engine, and confirmed the project is splitting into two versions. This is the payoff of a long-promised rewrite.

The through-line from February to June is Circle moving up-stack: from shipping individual features to assembling an AI-assisted operating layer, a two-sided marketplace for member acquisition, and a services arm. Automation and distribution are becoming as central to the pitch as the tooling itself. Each monthly release adds another rung on that ladder rather than broadening the feature surface sideways.
Expect the next releases to extend Circle AI beyond initial setup into ongoing operations, and to widen what MCP-connected agents can query and act on inside community data.

Today it released the first public beta of 2.0, rebuilt on a new database (DB) storage engine, and confirmed the project is splitting into two versions. This is the payoff of a long-promised rewrite.
The DB rewrite moves Logseq off Markdown-file storage toward a database model, the prerequisite for the faster queries, reliable sync, and multi-device support the file-based app has struggled to deliver. Expect the 0.10.x line to slide into maintenance while 2.0 stabilizes. The formal split into two versions signals Logseq intends to keep supporting local Markdown graphs rather than force-migrate everyone.
Near-term releases will be rapid 2.0.x betas hardening the DB engine and the Markdown-to-DB migration path; a stable 2.0 hinges on how cleanly existing graphs import.
