Lacuna is an AI music studio with two craft agents. Music agent: hum or describe — composes vocals + arrangement, no music theory needed. Lyrics agent: a real workspace with real-time syllable counter, automatic end-rhyme detection (color-coded pairs), AI rhyme suggestions, and verse/chorus/bridge templates. Thinks with you, doesn't write for you. MIDI tools: text/image/PDF to MIDI, sheet music scanner, in-browser MIDI editor — take the output into your DAW. 9 languages. Free tier, no card.

Hey Product Hunt 👋 I'm Louis, building Lacuna. Most "AI music generators" stop at one prompt → one track. Lacuna treats songwriting as three connected craft surfaces, with two agents that collaborate instead of just generating. **Music agent** — Hum or describe a feeling, the agent composes vocals + arrangement. Conversational; no music theory needed. **Lyrics agent** — A real workspace, not a chatbox. Real-time syllable counter per line so you control rhythm. Automatic end-rhyme detection with color-coded pairs so weak rhymes are visible. AI rhyme suggestions and verse/chorus/bridge templates on demand. The agent thinks with you, it doesn't write for you. **MIDI tools** — Text-to-MIDI, image-to-MIDI, PDF-to-MIDI, sheet music scanner, and an in-browser MIDI editor. For when you want to take an idea into Logic / Ableton / FL. 9 languages. Free tier with monthly credits, no card. Paid plans add commercial license, more credits, priority queue. Treat this as v0 — just starting. Would love brutal feedback, especially from anyone who actually writes songs.
