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 3.0 beta closes enterprise auth and SEO gaps at sprint pace

Wiki.js is running a dual-track strategy: v2.5.x is in maintenance, collecting only security and bug fixes, while v3.0.0 moves through beta weekly with substantial new features. The v3 beta has concentrated recent drops on two converging pillars — enterprise authentication (Entra ID, LDAP, SAML, Discord with group-to-role mapping) and operations infrastructure (Audit Log, admin metrics, sitemap serving, prerendering for anonymous requests). All active development runs through a single committer, shipping multiple named features per weekly beta build.

Capacities vs Wiki.js: editorial side-by-side

C5.0

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 3.0 beta closes enterprise auth and SEO gaps at sprint pace

◆ Current state

Wiki.js is running a dual-track strategy: v2.5.x is in maintenance, collecting only security and bug fixes, while v3.0.0 moves through beta weekly with substantial new features. The v3 beta has concentrated recent drops on two converging pillars — enterprise authentication (Entra ID, LDAP, SAML, Discord with group-to-role mapping) and operations infrastructure (Audit Log, admin metrics, sitemap serving, prerendering for anonymous requests). All active development runs through a single committer, shipping multiple named features per weekly beta build.

◆ Where it's heading

The v3 beta is systematically filling the gaps that have kept Wiki.js out of enterprise environments: SSO across major identity providers, compliance tooling, SEO readiness, and theme customization for whitelabeled deployments. Each week's build adds a category that a production deployment actually requires. The remaining areas not yet visible in the beta changelog are storage/sync providers and full editor-module parity with v2 — those gaps are the logical preconditions for an RC.

◆ Prediction

The next beta cycle will likely address storage backends and remaining editor modules. A release candidate becomes the natural next step once those surface areas are covered.
