Council AI (https://councilai.app/) queries multiple language models at the same time from a statement and highlights their points of agreement and disagreement.

The question can be sent simultaneously to five models: ChatGPT, Gemini, Claude, Sonar (Perplexity) and Grok or to an avatar of famous people.
A summary shows a percentage of agreement between the answers.

The “Debater” mode allows two camps to debate, with points of agreement and summary.

Thematic “advice” is ready to use (optimistic/pessimistic/realistic, time/money/stress, parenting styles…), and it is possible to create them.

Note: English interface, French support.

Free and without an account with access to only certain models, seems unlimited.
