Frequently asked questions
How does the chord detection work?
We download the audio from YouTube, then run it through a signal-processing pipeline. First we separate harmonic content from percussion (HPSS), then track the beat grid with a neural beat tracker (madmom), and finally match each beat window against a bank of 24 chord templates (all major and minor keys). The detected key is used to resolve ambiguous chords and keep the result musically coherent.
How accurate is it?
On guitar-driven and piano-driven songs — pop, rock, folk, country — accuracy is typically very good. It handles open chords, barre chords, and common seventh chords well. Dense orchestral arrangements or songs with heavy electronic production are harder. Premium users can enable HQ mode (Demucs stem separation) which isolates the harmonic instrument before analysis and gives significantly better results on complex tracks.
What kinds of songs work best?
Acoustic guitar, solo piano, singer-songwriter, and classic rock tracks get the best results. Songs where a single chordal instrument is prominent in the mix are ideal. Heavily produced EDM, rap beats without harmonic content, or songs where the melody heavily obscures the harmony may give less accurate results.
Does it work for any YouTube video?
Yes, as long as the video is public and has audio. Private videos, age-restricted videos, or videos blocked in certain regions can't be processed. Covers, live performances, and studio recordings all work — we analyze whatever audio is in the video.
How long does analysis take?
Most songs are ready in under 2 minutes. A 4-minute track typically takes 60–90 seconds on standard mode. HQ mode (Demucs) runs stem separation first, which adds 2–4 minutes depending on song length. You'll get an email when it's done so you don't have to wait at the screen.
What's the difference between standard and HQ analysis?
Standard analysis works directly on the full mix. HQ analysis (Premium only) first runs Demucs — a state-of-the-art source separation model — to isolate the guitar or piano track from the rest of the mix. Chord detection then runs on the clean instrument signal, which removes vocal interference, drums, and bass from the calculation. The result is noticeably more accurate on busy arrangements.
Can I export chords to use in other apps?
Yes. Premium users can export any song as a printable PDF (great for rehearsal or stage use) or as a .cho ChordPro file compatible with OnSong, Songbook Pro, and most tab editors. The ChordPro file includes all chords with timing markers.
Is my data private?
Analyzed songs are stored on our servers so they can be shared publicly and re-used by other users who analyze the same YouTube video — this is how we avoid re-processing the same song twice. Your personal library, transpositions, and capo settings are private to your account. We don't sell any data.
Do I need a credit card to sign up?
No. The free plan gives you 3 analyses per month with no card required. You only need payment details if you upgrade to Premium.
