Say “Council”. Pro
Several AIs look at the same question and nobody changes files. Your AI sums it up: one recommendation, and where they disagree.
You talk.
Your Duo builds.
Prometheor Duo
Like Claude Duet or Dots, but you pick both sides, from any company.
Prometheor Duo pairs the AI you like to talk to with the coding agent you choose, from any company. Say what you want, even from your phone. Your Duo works in your project on your Mac, settles the small questions itself and tells you when it's done.

Waiting for work
Claude Code asks a lot.
Grok Bot answers most of it.
Coding agents stop every few minutes: which format, which file, may I run this? So you sit next to them. In a Duo, the AI you talk to settles the questions about how. Every question and answer stays in the session, so you can read along or step in any time. Only what really needs you reaches you.

Only use Claude? Duet is a great pair. Prometheor is for people who use more than one AI, and Duet or Dots can be one of them.
Based on public information as of 9 November 2026. Prometheor is not affiliated with Anthropic or OpenAI. It doesn't make any AI smarter; it gives you the choice.
Change the AI.
Keep the project.
Every folder on your Mac becomes a project with all its tasks and history, whichever app did the work. Run one Duo for the app and another for the website, side by side. Or write straight into a project yourself.
From your folders
Nothing to create. Folders and Git repos become projects on their own.
Several Duos side by side
Grok Bot with Claude Code for the app, Dots with Codex for the website. With Pro they run at the same time.
Memory per project Soon
Decisions, rules, status. Your AIs suggest, you have the last word.
Duo up front.
Every AI behind it.
Your Duo is who you talk to. Behind it, Prometheor still connects every AI you pay for, so a second opinion or a second pair of hands is one word away.
Say “Team”. Pro
They build one result together, one after another in the same folder, and you get one answer back.
Limit reached? It moves on. Pro
When one app hits its plan limit, the task moves to another app, even while you're away.
You approve.
Nobody else.
Your apps work with their own permissions and sign-ins, and nothing goes live unless you confirm it.
- In your apps, on your plans. Every session runs visibly in Claude Code, Codex, Cursor, T3 Code or Antigravity. Write into it any time.
- Logins stay with you. Your AI app logins stay on your Mac or with the app provider, never in Prometheor.
- Approvals stay with you. Commands, files and sign-ins are confirmed in the app on your Mac.
- Going live only on your go. Your AI asks, you tap “Go”.
- One word stops everything. Say “stop everything” or press the button.

Questions
What is Prometheor Duo?
Two AIs working as a pair. One you talk to: Grok Bot, Dots, Duet or Muse. One that builds on your Mac: Claude Code, Codex, Cursor, T3 Code or Antigravity. You only talk to the first. It hands over the work, settles the questions about how and brings you the result.
How is it different from Claude Duet or Dots?
Claude Duet works with Claude Code, and Dots work with Codex, each inside its own company. With Prometheor Duo, any AI you talk to can run any agent on your Mac, one project holds the work of every app, and Council, Team and one stop work across all of them. It doesn't make any AI smarter; it gives you the choice. If you like Duet or Dots, keep them and use them as the AI you talk to.
Do I need Duet or Dots?
No. Grok Bot and Muse work too, and so does a regular ChatGPT or Claude chat. Dots and Claude Duet aren't available everywhere yet. Pick whichever AI you like talking to, and change it whenever you want.
Will my AI tell me when it's done?
Grok Bot and Dots message you on their own, and Duet checks in on its own schedule. Muse and a regular chat reply when you next write, so the Prometheor App tells you right away on your Mac.
Does my AI answer everything for me?
No. It settles questions about how to do the work. Approvals, sign-ins, money, going live and anything your customers will see always come to you.
Do I need a Mac?
Yes, to start. You can talk from anywhere, including your phone, but the agents build on your Mac. If it's asleep, a Claude Code routine of yours can take the task in the cloud; otherwise it waits up to 24 hours and starts when your Mac is back.
What's the difference between Duo and Projects?
Duo is who you talk to and who builds. Projects are where the work lives: the folder with all its tasks, its memory and its history. Every Duo task runs in a project.
Can I stop everything?
Yes. Tell your AI “stop everything”, or press “Stop everything” in the app or the dashboard. No AI takes new work until you press “Resume”.
How do I cancel?
On your account page at app.prometheor.com, or with Cancel contracts here at the bottom of this page. You keep access to the end of the period, and you can withdraw within 14 days for a full refund.
