Tasks stay until they’re done.

The month, right beside it.

A library that looks like yours.
Folders and notes with their own icon and color, your recent pages up front, and tags that gather everything on a topic.
Every meeting has its note.
What you wrote last time is right there. And a Quick Note floats over the call, offering to become this meeting’s note.

Your notes stay yours.
Every day and every note is a plain Markdown file in a folder you choose. Open them in any app, back them up your way, and let your iCloud Drive keep every device in sync.
Bring your notes from another app.
On the Mac, File › Import Notes… reads Obsidian, Apple Notes, Bear, Day One, NotePlan, Logseq, Craft or any folder of Markdown. You see what it found before anything is written.
Each note where it belongs
Daily notes go to their day. Everything else goes to Notes, with its folders.
Import twice, get it once
Karu remembers what it brought, so running it again only adds what is new.
Undo, exactly
Undo Import takes out what Karu wrote and nothing else. A backup comes first.
From Apple Notes too
Export them as Markdown from Notes, then choose that folder. The images come along.

Private by default. Open when you choose.
Karu’s intelligence runs on your device. When you want a bigger model, your notes are already plain Markdown, so an assistant you trust, like Claude Code or Codex, can read the folder you hand it, every day at once, without connecting or exporting anything.
Nothing leaves without you.
Karu never sends your notes anywhere. You decide what an AI sees, one folder at a time.
Read just as they are.
Days, tasks and links are plain text with a few simple marks, so an assistant on your Mac understands them without a plugin.

Questions, answered.
Where are my notes?
In a folder you choose, as plain Markdown files. Open them in any app, move them or back them up. Karu has no server, so it never keeps a copy.
Can I bring my notes from Apple Notes, Obsidian or another app?
Yes, on the Mac: File › Import Notes… reads Obsidian, Bear, Day One, NotePlan, Logseq, Craft or any folder of Markdown, and shows what it found before writing anything. From Apple Notes, first export the notes as Markdown (File › Export As › Markdown); the export keeps the images, but not each note's date or folder. Importing twice never duplicates, and Undo Import takes it all back.
Does it work with Claude, ChatGPT or Codex?
Yes, with nothing to connect. Your notes are Markdown files, so Claude Code, Codex, Copilot or Gemini CLI can read the folder you point them to, and in ChatGPT or Claude on the web you upload the files you want. To keep everything on your Mac, Ollama runs the model right there. Karu itself never sends your notes anywhere.
Which devices does Karu run on?
Mac, iPad and iPhone, including iPhone Duo, with macOS 26, iPadOS 26 or iOS 26. Your iCloud Drive keeps the same notes on all of them.
What is free and what is Karu Pro?
Karu is free. Karu Pro adds three optional packs, Personality, Meetings and Widgets, each a single purchase that stays yours, never a subscription.
Does it work without internet?
Yes. Your notes live on your device, and the Apple Intelligence features run on it too. Only link previews and iCloud sync use the network.
Is Karu in my language?
Karu speaks English, Spanish, Portuguese, French, German, Italian and Japanese, and your notes can be in any language.
How do I join the beta?
