About

Hey, I'm Louis — a full-stack developer and indie maker. I spent years as a technical lead in the AI industry before going indie. I build AI-powered tools that solve real problems for real businesses — not just demos. I care about shipping fast, keeping margins healthy, and building things people actually pay for. Currently working on new AI SaaS products in the image editing space. Always happy to connect with other indie makers and builders.

Lacuna - An AI music studio for the songs inside you

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.
