Create with AI. Own the credit.
Letron is an AI DAW that records every creative decision you make — so your music can be published, verified by labels, and earn royalties.
No music degree required. Just your ears, your taste, and your decisions.
Three things that change how you make music.
Skill — Train the AI on your sound
Mark the moments that hit right. Letron maps 20+ musical dimensions into a Style Profile that's uniquely yours. You're still calling the shots — AI just learned to listen to you.
How Skill works →Replace — Stuck sections, solved your way
Highlight any section. Letron pulls candidates matched to your Skill — not generic AI output. Play them back, pick one, and it's logged.
See Replace in action →Ledger — Proof your music is yours
Every note, every Replace, every edit — written in order, permanently. Export your .llg and show labels a real record of how your track was built.
