What it does

  • Plain files, yours

    Notes are Markdown files in a folder you own. An Obsidian vault opens as it is.

  • Linked thinking

    Links, backlinks, tags and a graph of how your notes connect.

  • Dates become plans

    Write “call mom tomorrow 3pm” and it's in the Planner. “Every Monday” repeats, in four languages.

  • Alarms where you write

    Add “notify me”, “avísame” or “알려줘” next to a time, and your phone or computer rings.

  • Sync and teams

    Your devices stay in step. Share a folder with your team and edit together, live.

  • AI with your own key

    Summaries, translation and questions answered from your notes, with your Claude key. Search by meaning runs on your device.
