PitchPilot – Chrom Extensions

Vocal range analyzer and automatic key transposition for singers.

PitchPilot is a smart music companion for singers and guitarists. It listens to your voice, detects your natural key and vocal range, and automatically suggests the right transposition for any chord or tab page — so you can stop straining and start singing.

How it works:

1. Open any chord or tab page (Ultimate Guitar, Chordie, and more)
2. Hit Record and sing a few bars into your microphone
3. PitchPilot detects your vocal key and range in real time
4. It compares your voice to the song’s key and suggests the exact transposition
5. Hit Apply — the chords on the page update instantly
