Use any AI you like
Plug in the big names like OpenAI, Anthropic, and DeepSeek, connect tools you already run such as Ollama or LM Studio, or use an AI built right into the app. Six easy ways to connect.
MAOS Mac OSmacOS build
A smart AI assistant that lives on your Mac.
MultiAgentOS for Mac is a friendly desktop assistant you can chat with all day. Ask it to draft an email, dig through your files, research a topic, or tidy up a folder, and watch it do the work right there on screen. It runs on any Mac, keeps your conversations private, and even works with no internet at all.
What you can do with it
A helping hand for whatever you are working on.
Chat with it like a colleague, hand it a task, and let it open the right tools, work through your files, and take action on your Mac, always with your say-so.
Works without internet
An AI comes built in, so you can start chatting straight away with no account and no setup. On a plane or off the grid, it keeps working, and your prompts and files never leave your Mac.
Private by design
Any passwords or sign-in keys are stored safely in the Mac's built-in Keychain, never in plain text. Nothing is tracked, no logs are kept, and your chats stay on your machine.
Gets hands-on for you
It can move the mouse, click, type, scroll, take screenshots, and open apps to carry out a task end to end. You stay in charge, since it asks before every action it takes.
The right tool, right there
Need a web browser, a code editor, a file viewer, or a document open? The assistant slides the right panel in beside your chat when a task calls for it, then tucks it away again.
Helpers for bigger jobs
Got a larger task? The assistant can spin up little helpers to tackle parts of it in the background, each with clear limits you set, then bring the finished results back to you.
A closer look
Everything in one tidy window.
Set up your AI, open files to work on, and keep typing to the assistant, all in the same place. No hopping between half a dozen apps to get something done.
Pick your AI in seconds
Connect a service like OpenAI or Anthropic, use an AI on your own machine, or go fully offline, all from one simple settings panel.
Edit files side by side
Open your files and folders right next to the chat, so you can tweak something and keep talking to the assistant without losing your place.
