Hey Product Hunt 👋 I’m excited to share MultiChat with you today. The idea came from a workflow I was already doing manually over and over again: opening ChatGPT, Claude, Gemini, Perplexity, and other tools in separate tabs, pasting the same prompt into each one, then trying to compare the answers and figure out which response was actually the most useful. It worked, but it was slow, repetitive, and honestly exhausting. So I built MultiChat to make that workflow much simpler. With MultiChat, you can: send one prompt to multiple AI models compare answers side by side spot agreement, contradictions, and weak responses faster Then I added a few more tools around that workflow: AI Summary → creates a short combined takeaway from multiple responses AI Judge → scores which model followed the prompt best Prompt Optimizer → improves rough input before sending it to the models I originally built this for myself, but I’m launching it because I think a lot of people are already doing some version of this manually. Would love your honest feedback: What use cases does this feel most useful for? What would make it more valuable for your workflow? What’s missing? Thanks for checking it out 🙌
