Caliu
Keep Markdown notes offline with tags, sync, and source editing.
A local-first notes app for Mac, iPhone, iPad, and the web, with Android available in beta. Write in a rich inline editor or switch to raw Markdown, organize notes with nested tags, and work offline. The Mac app can connect a folder of plain Markdown files and pick up external edits. Core writing, tags, sync, and Markdown export are free. Caliu Pro adds server-backed version history, API access, and additional export formats; history needs an internet connection. Pro PDF export is available on Apple apps, while HTML export also works on the web.

Meeting transcription can run locally on macOS 26 or with an optional Whisper model; earlier systems and some languages may use Apple's servers.
