Clark for Mac

The AI note taking app for Mac that saves your to-dos and hands them to your AIs.

Please read this before you install.

Recording is your responsibility

Clark listens during your calls, in person when you turn it on, and all day only if you choose. That includes other people, not just you. It turns speech into text on your Mac, sends the text to Anthropic’s Claude to be understood, and saves what matters to your Clark account. The AIs you connect see what Clark saved, and full conversations only if you allow it for each AI.

Laws on recording conversations differ by country and state, and some places require everyone in a conversation to agree before it is recorded. You are responsible for knowing the rules where you are, for telling people that Clark is on, for getting their consent when it is required, and for turning Clark off when you should not record.

Clark’s setup asks you to confirm this before it starts listening: “I understand that I am responsible for using Clark lawfully and for any conversations it records.”

This is not legal advice. You can turn Clark off any time from the menu bar.

Clark’s commitments

  • Clark never uses your conversations to train AI models.
  • Clark never sells your data or uses what it hears for ads.

What leaves your Mac

  • Your speech is turned into text on your Mac.
  • The text goes to your Clark account and to Anthropic’s Claude, which reads each conversation and saves what matters.
  • The AIs you connect see what Clark saved. They see your full conversations only if you allow it for each AI.
  • Clark keeps no audio, and speech audio never leaves your Mac.
  • To check for updates, Clark asks the Clark website for its latest version. It sends only the version you have, never your account or conversations.

The Privacy Policy lists every service Clark uses.

Install Clark

  1. Open the download

    Double-click Clark.dmg in your Downloads folder.

  2. Drag Clark to Applications

    In the window that opens, drag Clark onto the Applications folder.

  3. Open Clark

    Open Clark from Applications. macOS asks once whether to open an app downloaded from the internet: click Open.

From 0.5.1, Clark updates itself. When a new version is ready, Clark lets you know, and you install it from the menu bar.

Already have Clark 0.4.0 or earlier? Update by hand this once: quit Clark from the menu bar, open the new download, drag Clark onto Applications and choose Replace. No need to delete the old one.

Coming from 0.6.1 or earlier? Clark is now notarized by Apple, so macOS asks once more for the microphone and call audio, and Clark may ask you to sign in once more. Your voice and settings stay, and later updates keep your permissions and your sign-in.

Set up in a few minutes

  1. Sign in to Clark

    Clark’s setup asks you to sign in. No account yet? Make one right there with your email and a password, then type the code from the confirmation email.

  2. Read how Clark works

    Clark’s setup shows when it listens and how to tell people Clark is on. Then you confirm that recording is your responsibility.

  3. Allow the microphone and call audio

    Click Allow for the microphone. Call audio is optional: it lets Clark hear the other people on your calls through the call app’s sound (in a browser call, every tab of that browser), never music or videos in other apps. macOS calls this system audio recording.

  4. Teach Clark your voice

    Say a few sentences so Clark knows your voice. The first time, it downloads its on-device speech model (a few hundred MB). Then say “Hey Clark, what can you do?”

  5. Connect your AIs

    In your dashboard, open Connect AI and add Claude, ChatGPT, Grok or Muse. Clark hands each to-do to the one that fits.

That’s it. Clark starts on your next call, or when you turn it on, and what matters shows up a few minutes after each conversation.
