Hey Product Hunt! 👋 I'm Adam, and I built Melogen because I kept running into the same problem: I'd ask ChatGPT or Claude to write a melody, get back a wall of JSON — and have absolutely no way to hear it. So I built the missing piece. Melogen lets you paste any LLM-generated melody JSON, hear it play instantly on a piano roll, edit individual notes, and export to MIDI for your DAW. No music theory required. No DAW needed just to preview. Just paste, play, and create. I tested it across ChatGPT, Claude, Gemini, and Grok — the differences in how each model "thinks" about music are genuinely surprising. (Full breakdown in our YouTube video if you're curious.) Melogen is free to use. Pro plan unlocks higher limits and more features. Would love your honest feedback — especially from anyone who's tried getting usable music out of an LLM before. What was your biggest pain point? Try it free → melogen.app
