Koru

What is Koru?

Local-first notes and documents app that opens AI coding agents as tabs and syncs peer to peer.

Who is Koru best for?

Koru is best for developers who keep notes beside AI coding agents and want them stored on their own devices.

• Notes beside coding agents

  Claude, Codex, Gemini and other agents open as tabs next to your documents and edit the workspace through Koru's local MCP server.

• Offline, several computers

  Each workspace is stored locally as a CRDT snapshot, so it works offline and merges cleanly when devices sync directly.

• Leaving Evernote or Notion

  It imports Evernote .enex files, Notion, OneNote, Google Docs, Markdown and TextBundle, and exports to Markdown or TextBundle.

How much does Koru cost?

Koru Local is free with no account, and Koru Cloud adds always-on sync, backup and 100 GB of storage for $9.99 a month.

A self-hosted sync server is listed as coming soon. The iOS and Android apps are in development, and the macOS build needs an Apple silicon Mac. Full pricing on koru.do. We checked these prices on 8 Nov 2026.
