What's New?

A new feature guide covers every section of the app with tips, keyboard shortcuts, and how-tos. Find it in Quick Links on your dashboard.

Check out hand-picked videos worth practicing on your dashboard, feed, or the new Featured page. Each featured video includes editorial notes and links to the original with all its markers and loops intact.

Reduce or enhance vocals in real time using a machine learning model that runs entirely in your browser. A neural network listens to the audio stream, builds a spectral profile of the vocal frequencies, and applies it on the fly — no server round-trip required. Slide toward Reduce to push vocals into the background, or toward Enhance to bring them forward. Works with both YouTube videos and uploaded audio. Requires the Slow Down browser extension v1.1.0 or later (should update automatically, or grab the latest from the Chrome Web Store).

Slow Down now detects the musical key of your videos automatically. Audio is captured by the browser extension, encoded, and analyzed server-side to determine the key. The detected key is displayed in the song info panel. Still in beta — results are generally accurate but may occasionally miss, especially with short clips or complex harmony. I'll keep refining it. Requires the Slow Down browser extension v1.1.0 or later (should update automatically, or grab the latest from the Chrome Web Store).

Automatic BPM detection for your videos. Like key detection, audio is captured by the extension and analyzed server-side. The detected BPM is displayed in the song info panel and stays synced with the speed controls — when you slow a track down to 75%, the BPM display updates to show the effective tempo so you always know exactly how fast you're practicing. Still in beta — accuracy is good for most tracks but may be off for very slow, very fast, or rhythmically complex pieces. Requires the Slow Down browser extension v1.1.0 or later (should update automatically, or grab the latest from the Chrome Web Store).

New dedicated Practice Tools area — a growing collection of tools to level up your practice sessions. Access it anytime from the dashboard. It's also available in the video player as a compact remote control.

A full-featured metronome with tap tempo, time signatures (2/4, 3/4, 4/4, 5/4, 6/8, 7/8, and custom), subdivisions (quarter, eighth, triplet, sixteenth), multiple click sounds (classic, mechanical, woodblock, rimshot), swing control, accent/ghost/mute per beat, random mute for independence training, and a gradual tempo trainer that automatically increases BPM over time. Available standalone or as a compact remote control inside any video.
