Hey Product Hunt 👋 I kept doing the same thing whenever a prompt actually mattered: paste it into ChatGPT, then Claude, then Gemini, and squint at three tabs to work out which answer was best. It's slow, and you lose the thread the second you want to dig into one of them. So I built Compare LLMs. You write one prompt, it runs across ChatGPT, Claude, and Gemini at the same time, and every answer lands side by side. You can ask follow-ups in place, then export the whole thing to Markdown once you've found the response worth keeping. The part I care about most: it runs locally in a private utility. Your prompts and responses don't hit a server of mine, so it's private by default. It's part of TransferLLM, which also moves and syncs your chat history between those same three tools. I'd love your honest feedback, especially on which features or model pairings you'd want next. I'll be here all day to answer anything.
