Tell it your rules.
In plain English. No code.
Wrap any model in executable policy, evidence, and approval gates. It follows your rules instead of just hearing them.
Drafting the email and checking it against your policy.
Plain English in. A machine contract out, enforced by code, not a prompt.
Sound familiar?
They look great in a demo, then cite a number they never checked or skip the step that mattered. Magi follows the rules you set, on every task, and stops when it can't.

Why Magi

FAQ
Magi lets you build an AI agent tailored to your work, one that follows the rules you set. You describe how your work should be done in plain English, and Magi builds an agent that checks every action against those rules before it acts.
Yes. The hard part (verification, permissions, and logging) is already built in. You just add your rules, so getting a working agent takes minutes, not days.
No. You describe your rules in plain English. Developers can go deeper with the open-source runtime, but it's not required.
Most off-the-shelf agents do the same thing for everyone, and you just hope they follow your instructions. Magi builds an agent around your specific rules and enforces them on every action, so it can't quietly skip the step that matters.
Yes. Magi is open source first. Self-host the runtime, bring your own keys, and switch to Cloud whenever you want managed infrastructure.
Claude, GPT, Gemini, and local models. Magi is provider-neutral, so you can swap models behind the same rules.
