Open an MP3 and ChordLift transcribes the lyrics with AI (Whisper), detects the chords and the key, and places every chord right above the word being sung when it hits — just like an Ultimate Guitar chart. Fully automatic, runs on your own computer, your music never leaves your device.

Whisper turns the singing into text with a timestamp for every single word — in English, Spanish, and 90+ languages.
A chromagram analysis finds major and minor chords, when they change, and the song's key.
Each chord lands above the exact word being sung when it starts. Intro chords get their own line. Edit and save as .txt.
Shift to any key with one click. Copy the chart or download it as a clean .txt you can print or share.
No account, no server, no upload. The whole app is one HTML file. It even works offline once loaded.
Apps that do this charge a subscription. ChordLift is a gift to musicians — open source, no limits, no first-minute-only tricks.
