Music Scale Finder — listens to whatever's playing in a tab and figures out which musical scale/key the song is in. Scalefy listens to whatever's playing in a browser tab and tells you which musical scale (key) the song is in — great for musicians who want to jam along, transcribe, or just understand a song faster. HOW IT WORKS 1. Play a song in any tab (YouTube, Spotify Web Player, SoundCloud, etc.) 2. Click the Scalefy icon and hit "Start Listening" 3. Pick that tab in Chrome's share picker 4. Scalefy listens for about a minute, then confirms its best guess — the detected scale, its notes, and a confidence rating 5. Click "Check Next Song" anytime to analyze something new WHY IT'S DIFFERENT - No sign-up, no account, no downloading audio files - Runs entirely on your device — audio is analyzed in memory and never recorded, saved, or sent anywhere - Uses an established music-theory approach (key-profile correlation) rather than guessing from a black-box model WHO IT'S FOR Guitarists, pianists, producers, music students, or anyone who's ever paused a song and thought "what key is this even in?" LIMITATIONS (we'd rather be upfront) Works best on tonal music with a clear key center — pop, rock, folk, and most Western music. Less reliable on atonal music, songs that change key partway through, or very noisy/percussive audio.
