What is Outline?
Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.
Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.
What is Trilium Notes?
The TriliumNext fork spent its early betas making the app trustworthy to install
Three beta releases from early 2025. The work is dominated by distribution and access concerns: signed Windows binaries obtained through a donated EV certificate, signed macOS builds, multi-factor authentication that required a database version bump, basic right-to-left content support, and repaired migration paths from the original Trilium. Nothing has been published to this feed since March 2025.

Outline

Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.
◆ Current state
Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.
◆ Where it's heading
Outline is positioning itself as an agent-native knowledge base rather than just a polished wiki. The pattern across the last several releases is deliberate: MCP support expanded significantly in April, Open Knowledge Format export added portability in September, and WebMCP makes the agent integration surface browser-accessible. The OKF export is also a meaningful portability move — structured markdown bundles that survive outside Outline reduce lock-in risk and could attract teams evaluating it against more closed alternatives.
◆ Prediction
Outline will likely expand the WebMCP tool surface — the April MCP work gave them a solid set of structured tools to expose, and WebMCP makes those available without setup friction. Expect more agent-facing capabilities (summarization, cross-document linking, task extraction) rather than another round of baseline UX polish.
Trilium Notes

The TriliumNext fork spent its early betas making the app trustworthy to install
◆ Current state
Three beta releases from early 2025. The work is dominated by distribution and access concerns: signed Windows binaries obtained through a donated EV certificate, signed macOS builds, multi-factor authentication that required a database version bump, basic right-to-left content support, and repaired migration paths from the original Trilium. Nothing has been published to this feed since March 2025.
◆ Where it's heading
These are the problems a fork inherits rather than chooses. Before adding features, the project had to make installs pass platform trust checks, let users migrate off the predecessor without an intermediate upgrade, and add authentication a self-hosted note store is expected to have. It is groundwork, done in the open, with contributors credited by name.
◆ Prediction
There is not enough recent activity to predict the next release. The feed has been silent for over a year, so whether the beta line continued elsewhere is the open question.
