Meeting notes are nice. Done work is better.

No. Clark finds them and hands them to the AIs you connect. They do the work, and Clark tells them to check with you before sending anything.

Yes. Turn Clark on from the menu bar when the meeting starts, and it listens through your Mac’s microphone. It hears everyone in the room, so tell people Clark is on. A few minutes after the conversation ends, it saves the to-dos, promises and details.

Yes, once connected (ChatGPT needs a Pro, Business, Enterprise or Edu plan). Your AIs see what Clark saved, and your full conversations if you allow it, so they can look up what you discussed without you repeating it. Clark doesn’t change what Claude or ChatGPT remember on their own.

Granola is an AI notepad for meetings. Clark is built around to-dos: it saves what you agreed to do in conversations and hands each one to the AI that fits. Want your to-dos handled, not just written down? That’s Clark.

No. A call starts Clark, with a banner so you can tell people, and Clark stops when the call ends. In person, it listens only when you turn it on, and all day only if you choose. While it listens, it hears everyone in the conversation. It pauses while your Mac is locked or asleep. No audio is kept: Clark turns speech into text on your Mac, and speech audio never leaves it.

Yes. When a call starts in Zoom, Teams, Slack, FaceTime or Webex, or in your browser, Clark starts too and shows you a banner, and it stops when the call ends. You can turn that off in Settings. If you allow call audio, in setup or later in Settings, Clark hears the call app’s sound, so it hears the other people too. Only that app’s sound, never music or videos in other apps. But in a browser call, it hears every tab of that browser. It understands English and Spanish, even in the same conversation. During a call, “Hey Clark” answers in writing in the menu bar instead of out loud, unless you turn on speaking during calls in Settings.

Only if you tell them. When a call starts Clark, it shows you a banner with a notice to copy into the call’s chat, and in person it can nudge you when someone new talks. One line works: “Heads up, I use Clark to keep track of what we agree on. Okay with you?” In some places everyone has to agree before you record.

The AIs you connect see what Clark saved, with the context Claude wrote for each item and each conversation’s title and date. They see your full conversations and your Maybe items only if you allow it for each AI. They can add a to-do when you ask (or suggest one under Maybe on their own), delete a to-do when you ask (you can restore it), and say a task is done, which waits for your OK unless you told them it’s finished. Nothing they do erases what Clark saved.

No. Clark never uses your conversations to train AI models. The AIs you connect follow their own settings, so check their training options too.

No. Clark never sells your data or uses what it hears for ads.

If your Mac has Apple silicon (M1 or later) and runs macOS 26 or later, yes. To check, choose Apple menu > About This Mac. Intel Macs aren’t supported.

Clark is free during the preview. Each new account has a daily limit on how many conversations Claude reads and how many questions Clark answers. Past it, Claude reads the rest of your conversations the next day, and Clark answers questions again then. Whether you can connect Claude, ChatGPT or Grok depends on your plan with them.

Yes. Clark’s setup on your Mac 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. Every account can use Clark.
