What Loopra does

🔁

AB Loop

Set a start point (A) and end point (B) to loop any section of a song endlessly. Perfect for ear training and learning by ear.

🎚️

Speed Control

Slow down or speed up playback from 0.5× to 1.5× without affecting pitch. Ideal for transcription and practice.

💾

Save Loops

Name and save multiple loops per song. They're stored locally in your browser and ready whenever you return.

🎨

Visual Timeline

All your saved loops are shown as colored ranges on a timeline. See and navigate your loops at a glance.

🔒

100% Local

No accounts, no servers, no tracking. Your loops stay in your browser. Nothing ever leaves your device.

⚡

Instant Access

Open from Chrome's side panel — works alongside YouTube Music without interrupting what's playing.

How it works

1

Open YouTube Music

Navigate to any song on music.youtube.com. The Loopra icon in your toolbar will turn active.

2

Set your loop points

Click "Set Current Time" at point A, then again at point B — or drag the handles on the timeline directly.

3

Enable the loop

Toggle the loop switch on. The section plays on repeat. Adjust A and B on the fly and hear changes instantly.

4

Save for later

Give the loop a name and save it. It'll be there next time you open the song.
