Multi-AI Compare (Prototype)

Multi-AI Compare lets you ask ChatGPT, Claude, Gemini, and Perplexity the same question and view their answers together in a Chrome side panel. Choose which AI websites to use, send a prompt, and compare the responses in one place. You can continue a conversation, copy individual answers, and ask a selected AI to merge the available responses. Recent prompts and answers are saved locally in your browser for easy access. To use the extension, sign in to the AI websites you want to compare. Multi-AI Compare uses your existing browser sessions; it does not require API keys. The AI websites process your prompts according to their own terms and privacy policies. Multi-AI Compare is an independent tool and is not affiliated with OpenAI, Anthropic, Google, or Perplexity.
