Engine
Drop a track above, then ask me anything — "how's the low end?", "loud enough for streaming?", "what do I fix first?"
Why KOI BOI

⚡

ChatGPT for Mixing

🎯

Private by Design

Audio never leaves your machine. The AI only sees the numbers, never your music. Your key, your browser.

⚠ The AI does not train on your music. It only reads the audio features measured in your browser to explain the characteristics of your mix.

Built for producers

Made by Koi Boi — psytrance, 145 BPM, separated tracks, zero fluff.
