How it works

Get real answers from the confrontation between your favorite AI models.

Each model reads the previous responses and replies in context — not a side-by-side comparison, a real debate.
01You ask a questionText, file, image or voice — any topic.
02AIs debateEach model reads the full transcript and adds its perspective.
03Conversation flowsModels take turns in round-robin until your token limit or manual stop.
04Automatic stopToken cap reached or manual stop — never an infinite loop.
Models

Pick from the best models on the market — each reads the full shared transcript and contributes its unique perspective.

35 models across 4 tiers based on cost and capability. Choose freely based on your plan.

Agreement Score

After each AI message, a vector embeddings algorithm measures the semantic agreement level in real time.

Not an arbitrary score — a cosine similarity measure between the embeddings of each response. 0% = total contradiction, 100% = perfect agreement.
< 50%Strong disagreement
50–75%Partial agreement
75–85%Majority agreement
> 85%Strong agreement
Modes

7 specialized modes for every context — analysis, wellness, business, debate, or a fully custom prompt.
