- A visible Duo cursor you can follow

04Proactive help
It catches mistakes before you do.
Duo keeps an eye on what you are working on and speaks up when something is off. It flags the details you would miss and offers to take over the menial parts.
- Code
- A missing semicolon on line 201
- Facts
- About 340 million people, not 200
- Calendar
- An invite that clashes with your day
- Busywork
- Comparing flights with your usual bag
05Memory
Read, correct or delete anything. Kept on this Mac.
It remembers, so you don’t repeat yourself.
Duo learns your context as you work: people, projects, preferences. Memory is kept on your Mac, where you can read, correct or delete any of it.
- People
- Who is who, and how they like to talk
- Projects
- Where things live and what is in flight
- Control
- Read, correct or delete anything

10PrivacyCloud or local
Private where it matters.
Duo uses the cloud when you sign in, so it is quick and capable from the first minute. It never captures password managers or secure fields, and strips keys, passwords and card numbers from the screen text it checks and the memories it keeps. Want every answer to come from your Mac? Switch to small open models like Gemma and Duo keeps working offline.

12FAQQuestions, answered
Good questions.
Anything else? Ask Duo. Or write to us and a human will answer.
01Does Duo work offline?
Yes. Choose On your Mac in Settings and Duo answers with a small open model like Gemma, through Ollama, without a connection.
02Is my data private?
Your conversations, memories and learned actions are stored on your Mac. Duo never captures password managers or secure fields, and strips secrets like keys and card numbers from the memories it keeps. When you use the cloud, your message and the few memories that matter to it go with it. The privacy policy has every detail.
03Which Macs does it run on?
Macs with Apple silicon on macOS 14 or later.
04What is the difference between Ghost and Show mode?
Ghost mode works in the background through app scripts and accessibility, so your cursor and focus stay yours. Show mode moves an orange Duo cursor on screen so you can watch, and learn, each step. Duo uses it when you ask how to do something, or when an app can only be worked by looking.
05How do I open Duo?
Click the avatar in the corner, press Control twice, or say hey duo.
06What does Sidecar do?
Sidecar pairs your iPhone with Duo on your Mac. Follow what is running, answer it and start new requests from your phone, or use it as a side screen for Duo’s face.
