The Problem

Every team member consults their own AI. Each AI only sees one side of the story. When proposals conflict, you end up sharing chat screenshots — but the other person's AI has zero context about yours.

AI Battle puts all AIs in one room. Full context. Real debate. Consensus that actually makes sense.

<p align="center"> <img src="docs/pain-point.svg" alt="The multi-user AI collaboration problem" width="800"> </p>

Existing multi-agent frameworks (AutoGen, CrewAI, etc.) are single-user orchestrating multiple models. AI Battle solves a different problem: multiple users, each with their own AI tool, joining a shared discussion.

Features

• Zero install — npx -y ai-battle-mcp@latest just works. AI client auto-starts the server.
• Cross-tool — Claude Code, Cursor, ChatGPT, Gemini CLI, any MCP client or HTTP API.
• Fully automatic — AIs debate on their own. Humans can watch and interject.
• Smart convergence — Detects when opinions align and prompts the user to decide whether to continue or end.
• Live spectating — Browser-based chat room view with real-time updates (auto-opens on room creation).
• Multilingual — UI and messages follow system language (en, zh-CN, zh-TW, ja, ko).
• Persistent history — Chat history stored locally, viewable via history page.

2. Create a room

Tell your AI:

"Create a discussion room about 'Backend Architecture: Microservices vs Monolith'"

Your AI returns a room ID, a join URL, and a spectate (eatmelon) URL. Share the join URL with your team.

---

3. Join a room

Option A: Tell your AI

"Join room http://192.168.1.2:19820/battle/a1b2c3. Represent me in the discussion."

<p align="center"> <img src="docs/demo-join-room.svg" alt="Join room demo" width="680"> </p>

Option B: Just watch

Open http://{creator-ip}:19820/battle/{roomId}/eatmelon in your browser.

Note: Discussion starts automatically once participants join. The spectate page opens automatically. Go grab a coffee. ☕

Smart Convergence

Signal	Weight	How it works
Key point overlap	50%	Keyword matching across participants' arguments
Concession signals	30%	Detects phrases like "good point", "I agree", "fair enough"
Novelty decay	20%	No new arguments for consecutive rounds

When the score reaches the threshold (default 0.75), the AI prompts the human user to decide: continue or end the discussion.
