About
MAINS (Multi-AI Neural System) puts Claude, ChatGPT, Gemini and Grok around one table. In MAINS Council the four answer the same question together, read each other's replies, and build on a point, push back or change their minds while you chair every round. Invite the agents you already use, like Claude Code, Codex or Cursor, with a link, and bring colleagues into the same room from their browser. You decide who answers, when the next round starts and when to stop. The whole deliberation is your audit trail. Klaustrum sets the AIs working a problem round after round until they converge, and you can pause or redirect it any time. Artifex interviews you and writes the brief, or you write a Scope Card yourself. Deep Research searches the web first so everyone starts from the same brief, and on your own keys the Council makes real files like .xlsx and .pptx. Try two Council rounds free with no account and no card, then start free with Explorer.
Use cases
- Compare four AIs on a hard decision in one place
- Check research across models before you trust it
- Stress test a plan, contract or paper before you share it
- Bring colleagues and your own agents into one AI discussion
Features
- Problem
- AI answers in separate chats are difficult to compare and build on.
- How it works
- Claude, ChatGPT, Gemini, and Grok respond in one conversation, read the other replies, and can challenge or revise their views.
- Result
- A shared deliberation that the user steers and decides.
- Why
- The user can see how perspectives interact rather than receive disconnected answers.
- Problem
- A user may want input from agents or colleagues beyond the built-in AIs.
- How it works
- Users can invite agents with a link and bring people into the same browser conversation.
- Result
- AI agents and people can deliberate together in one room.
- Why
- Invited participants can contribute to the same discussion and see replies as they arrive.
- Problem
- Uncontrolled automation can take decisions away from the person responsible for them.
- How it works
- Users choose who answers, start the next round, and can pause or redirect deliberation; Klaustrum supports multi-round AI work with user intervention.
- Result
- Users retain control over the discussion and its outcome.
- Why
- The product keeps orchestration and final authority with the human.
- Problem
- A vague question can lead to unfocused deliberation.
- How it works
- Artifex interviews the user and writes a brief; users can also create a Scope Card with constraints, criteria, and context.
- Result
- The discussion starts with a more structured brief.
- Why
- Participants receive a clearer shared prompt and boundaries.
- Problem
- AI output may need to become a usable work artifact.
- How it works
- On users' own keys, Council can produce files such as spreadsheets or decks, and can draw when image generation is enabled.
- Result
- Users can save generated artifacts to their device.
- Why
- The result can be a file or image rather than only a text response.
What makes it different
- The four AIs read and challenge each other instead of answering in separate chats
- A human chairs every round and makes the final call
- Your own agents and people join the same room
- Your own keys work for any AI on any plan
