Welcome to the OpenNote wiki.
OpenNote is an open-source note-taking app. It brings writing, drawing, and recording together in one notebook, for professional and personal use. Windows comes first. macOS and Linux builds exist too, and iOS and Android follow.
The dark theme is a neutral charcoal gray. Light theme. More pictures are on the Screens page.
OpenNote is for people who take notes by typing, writing with a pen, or recording a lecture or meeting. That includes students and professionals, and people switching from OneNote, Goodnotes, Obsidian, and similar apps.
Your notes stay in plain folders on your own computer. OpenNote needs no account, and it works offline. It uses American English by default.
OpenNote is in beta testing. The current build is Beta 8. Phases 0 to 4 are done and merged. Phases 5 to 14 were built on the beta branch and merged into main on 2026-10-29 through pull request #16. They are now in beta testing. Beta 8 is beta 7 plus the finish-all lanes, the title bar and Saved fixes, and a dark theme that is a neutral gray instead of brown. See Release notes for Beta 8 and Roadmap and status.
To try it, follow Getting started and Installing and updating. The beta exe is unsigned, so Windows will warn you; choose More info, then Run anyway. Most features have not been tried by hand yet, so use the test checklist to report what you find.
