Polychat (https://polychat.co) is a chatbot based on ChatGPT 4o, ChatGPT o1 and Claude Sonnet 3.5 offering the possibility to compare models but also to “criticize” the answer given (GPT 4o by Sonnet 3.5 and vice versa).

Multiple parameters, pre-prompt, model change during conversation.

Share URL, JSON, PDF or TXT. Seems unlimited.
