A browser-based knowledge base with wiki-links, graph view, and AI — all backed by your GitHub repo.
Obsidian is beloved for local-first Markdown editing and its powerful graph view. But syncing across devices costs $8/month, sharing with others is cumbersome, and you need a desktop or mobile app installed everywhere. motion gives you the same Markdown-native, wiki-link, knowledge-graph experience — entirely in the browser, synced through GitHub, with built-in AI that works across all your devices without installing anything.

Built for developers and AI agents who think in Markdown
Open motion.wencai.app in any browser and you have a full-featured knowledge base editor. No desktop app download, no mobile app installation, no platform restrictions. Works on Windows, Mac, Linux, iPad, and Android out of the box.
Obsidian Sync costs $8/month to keep your vault in sync across devices. motion uses your GitHub repo as the sync layer — it is free, versioned, and gives you a full git history of every change. Every save is a commit.
motion ships with a built-in MCP server so AI agents (Claude, GPT-4, etc.) can connect and write directly into your knowledge base. No copy-pasting from chat windows — your AI collaborator edits notes like a teammate.
If you already use Obsidian, your vault is already compatible with motion. Connect motion to the same GitHub repo, and your [[wiki-links]], backlinks, and graph view all work exactly as before.
motion is free and open-source. Sign in with GitHub, connect a repo, and your knowledge base is live in seconds.
