One subscription replaces juggling separate ChatGPT, Claude, and Gemini accounts.

Many minds. One answer.

01

Ask once.

Type your question and pick how you want it answered — single model, side-by-side compare, or full debate.

02

Many models reply.

Up to 8 frontier models answer in parallel. You see each response as it streams, and which one wins on your criteria.

03

One answer wins.

A moderator model reads every response, debates the dissents, and delivers a single best answer with full attribution.

From a question to a finished artifact.

Drop a problem onto an infinite canvas. A panel of frontier models debate it, a judge ranks the strongest answer, and the winning concept renders as an image — all wired together in one continuous flow.

  • Pose a real problem — design briefs, research questions, hard tradeoffs
  • A panel of models proposes, debates, and converges on the strongest answer
  • Feed the verdict into image generation and end on a tangible artifact

Better answers, measured.

SUMMA's multi-model debate beats every single frontier model across reasoning, science, and code. Same prompts, several brains, one adjudicated answer.
