Capacities vs Wiki.js
A side-by-side editorial comparison of Capacities and Wiki.js — release velocity, themes, recent moves, and the top alternatives to consider.
Capacities vs Wiki.js: at a glance
What is Capacities?
Capacities ships API 2.0, pivoting from self-contained PKM toward a connected AI memory layer
Capacities is a structured personal knowledge management tool shipping at monthly cadence. In the past 4 months it has added AI Chat Connectors (connecting the space to ChatGPT, Claude, and Cursor), a developer-facing API 2.0, weblink reader and analysis, PDF annotations, AI image generation, and configurable AI model providers. The combination describes a product moving from self-contained PKM to a node in a broader AI-augmented knowledge graph.
What is Wiki.js?
Wiki.js 3 beta.705 ships a built-in MCP server and page ownership with lifecycle rules.
Wiki.js 3 is still marked not for production, but beta.705 adds a built-in MCP server, page ownership with lifecycle rules, a feedback board that reviewers can edit and categorize, and link completion in the markdown editor. PAT scopes get a clearer dialog, which matters now that tokens are how outside clients connect.

Capacities ships API 2.0, pivoting from self-contained PKM toward a connected AI memory layer
◆ Current state
Capacities is a structured personal knowledge management tool shipping at monthly cadence. In the past 4 months it has added AI Chat Connectors (connecting the space to ChatGPT, Claude, and Cursor), a developer-facing API 2.0, weblink reader and analysis, PDF annotations, AI image generation, and configurable AI model providers. The combination describes a product moving from self-contained PKM to a node in a broader AI-augmented knowledge graph.
◆ Where it's heading
The consistent direction is making Capacities connectable — first via AI chat integrations, then a proper developer API, and now deeper object types and AI media generation. The new Pro+/Believer+ pricing add-ons indicate AI usage is growing enough to require metered capacity. The platform is accumulating capability surface faster than a traditional note-taking tool and faster than comparable PKM competitors.
◆ Prediction
The most likely next move is deeper API-to-AI-connector integration, letting third-party agents create and modify Capacities objects programmatically — the existing connector work is the precondition for functioning as an AI memory layer rather than just a note store.

Wiki.js 3 beta.705 ships a built-in MCP server and page ownership with lifecycle rules.
◆ Current state
Wiki.js 3 is still marked not for production, but beta.705 adds a built-in MCP server, page ownership with lifecycle rules, a feedback board that reviewers can edit and categorize, and link completion in the markdown editor. PAT scopes get a clearer dialog, which matters now that tokens are how outside clients connect.
◆ Where it's heading
The v3 betas have moved from editor features (live notes, math, draft recovery) toward governance and machine access: personal access tokens in beta.672, then MCP and page lifecycle rules here. The project is building the controls an organization needs before trusting a wiki to AI clients and to long-lived content.
◆ Prediction
Expect more MCP tools and PAT scope options in the next betas, and lifecycle rules tied into notifications for review and expiry.
