What is Outline?
Outline is turning its team wiki into an AI-operable workspace while filling collaboration gaps.
Outline keeps shipping the connective tissue of a team wiki — access requests, email subscriptions for public documents, GitLab embeds, and richer tables. The standout recent move is a major expansion of its built-in MCP support, letting AI assistants patch, move, and delete documents and handle inline comments. The product now spans both human collaboration features and a growing agent-facing surface.
What is SiYuan?
SiYuan's 3.7.0 turns the note-taker into a scriptable, extensible platform
SiYuan is converging its long 3.7.0 dev cycle toward release. The cumulative changelog — repeated across many dev builds — centers on a kernel plugin system, a new command-line interface, configurable secrets and variables, a reworked settings UI, and a large batch of database, editor, and mobile refinements. A breaking change now requires an explicit 'serve' subcommand to run the kernel.

Outline is turning its team wiki into an AI-operable workspace while filling collaboration gaps.
◆ Current state
Outline keeps shipping the connective tissue of a team wiki — access requests, email subscriptions for public documents, GitLab embeds, and richer tables. The standout recent move is a major expansion of its built-in MCP support, letting AI assistants patch, move, and delete documents and handle inline comments. The product now spans both human collaboration features and a growing agent-facing surface.
◆ Where it's heading
Two threads run in parallel: incremental knowledge-base polish (toggle blocks, table editing, diagrams, PDF embeds) and a deliberate build-out of MCP so assistants can act on content rather than just read it. The cadence favors small, frequent collaboration features punctuated by the occasional structural move like MCP. Outline is positioning the wiki as something an agent operates, not just a place humans write.
◆ Prediction
Expect continued MCP surface expansion — likely deeper write operations and permissions handling — alongside steady collaboration features like the new access-request flow.

SiYuan's 3.7.0 turns the note-taker into a scriptable, extensible platform
◆ Current state
SiYuan is converging its long 3.7.0 dev cycle toward release. The cumulative changelog — repeated across many dev builds — centers on a kernel plugin system, a new command-line interface, configurable secrets and variables, a reworked settings UI, and a large batch of database, editor, and mobile refinements. A breaking change now requires an explicit 'serve' subcommand to run the kernel.
◆ Where it's heading
The headline direction is extensibility and automation: a plugin-capable kernel, CLI access, and secrets/variables move SiYuan from a self-contained app toward something developers can script and integrate. The breaking kernel API changes and the new serve subcommand are the cost of that platform shift. Underneath, steady editor/database hardening and broad localization continue.
◆ Prediction
Expect 3.7.0 to ship from the beta line with the plugin system and CLI as its banner features, followed by an ecosystem period of plugins and integrations building on the new kernel APIs. The repeated dev-build entries don't add direction beyond this.
