Joplin is a FOSS, multiplatform, Nextcloud-compatible note-taking app. Apparently, the dev uses Coderabbit and is now pulling integrated chatbot support from the optional AI plugin to the main (dev) branch. (Looks like Joplin Cloud, their note syncing and sharing service, has had chatbot integration for a year, but the user needed to opt into Joplin Cloud and the AI plugin was required.) At least the functionality is disabled by default but that might easily change later…
