Capacities vs Read the Docs
A side-by-side editorial comparison of Capacities and Read the Docs — release velocity, themes, recent moves, and the top alternatives to consider.
Capacities vs Read the Docs: at a glance
What is Capacities?
Capacities adds whiteboards and a global graph to its object-based notes.
Capacities is a structured personal knowledge tool shipping a named release about monthly. The October release adds whiteboards and a global graph view, a visual layer over existing notes, plus a polish pass. September brought audio recording and transcription, bulk property editing and AI chats that can edit and act on objects. AI image generation and a Pro+ tier with a larger AI budget arrived in August.
What is Read the Docs?
Read the Docs moves builds to Python 3.14 and Ubuntu 26.04 by default.
Read the Docs ships a dated release most weeks. October's notable changes: the default build image moved to Python 3.14 and Ubuntu 26.04, git:// URLs are no longer allowed, search scores pages by their best-matching section, and certifi was upgraded to distrust the compromised eMudhra CAs. Earlier October work added temporary environment variables in build commands, a size cap on build media, and the GitHub App as the default on Community.

Capacities
2.5COLLAB
Capacities adds whiteboards and a global graph to its object-based notes.
◆ Current state
Capacities is a structured personal knowledge tool shipping a named release about monthly. The October release adds whiteboards and a global graph view, a visual layer over existing notes, plus a polish pass. September brought audio recording and transcription, bulk property editing and AI chats that can edit and act on objects. AI image generation and a Pro+ tier with a larger AI budget arrived in August.
◆ Where it's heading
Two threads run together: AI that acts inside the workspace (connectors, chats that edit, a paid AI budget) and better ways to see and capture what is already stored (graph, whiteboards, audio). API 2.0 in July opened the space to outside tools.
◆ Prediction
Expect more AI actions inside chats and further work on the graph and whiteboard surfaces; the entries do not say whether whiteboards will reach the API.
Read the Docs
5.0COLLAB
Read the Docs moves builds to Python 3.14 and Ubuntu 26.04 by default.
◆ Current state
Read the Docs ships a dated release most weeks. October's notable changes: the default build image moved to Python 3.14 and Ubuntu 26.04, git:// URLs are no longer allowed, search scores pages by their best-matching section, and certifi was upgraded to distrust the compromised eMudhra CAs. Earlier October work added temporary environment variables in build commands, a size cap on build media, and the GitHub App as the default on Community.
◆ Where it's heading
Two threads run through the releases: a direct upload path for docs built elsewhere, which has had design docs, workflows and onboarding in September and October, and steady hardening of the build platform. Most entries are still lists of merged PRs with dependency bumps.
◆ Prediction
Expect direct upload to move toward general availability and more GitHub App defaults replacing the OAuth app.
