One question. Eight models. Zero blind trust.
Prism fans your prompt out to eight frontier AI models in parallel and shows every answer side by side. Then Debate Mode takes over: the disagreements get analyzed, the weak arguments get exposed, and the answer that survives is the one you keep.
No credit card. Claude · GPT · Gemini · Llama · +4 more.
Every model sounds confident. Even the wrong ones.
Ask one AI, get one answer — delivered with total certainty whether it's right or not. You'll never see the answer a different model would have given, the error it would have caught, or the stronger case it would have made.
The fix isn't a better model. It's a second opinion, a third, and an argument between them.
Compare Mode
Eight answers, one screen.
Your prompt runs against every model you select, in parallel. Responses stream into a side-by-side grid where differences in facts, reasoning, and framing are impossible to miss. One model failing never takes down the run.
Debate Mode
Hero featureDon't read eight answers. Interrogate them.
One click, and Prism's analyst layer cross-examines every response: real consensus vs. surface agreement, the genuine points of conflict, and the strongest case for each side — steelmanned, not strawmanned. A structured argument between frontier models, with a referee.
Workspace Mode
Ground every model in your documents.
Upload PDFs, docs, and notes. Prism retrieves the relevant passages and injects them into every model's context, so all eight answer from your material — with citations — instead of guessing from training data.
Production-Grade
An engine, not a chat toy.
Prism is the judgment layer we run in production: it powers Prism Judge, the multi-model quality gate inside Prism Suite's autonomous publishing pipeline. Every comparison logged. Every disagreement measurable.
