Turn your Suno songs into chord sheets you can actually play.
Drop an MP3 — any song, any genre. Five to ten minutes later you get chords over lyrics, in your key, ready to transpose, capo, and play along with synced highlighting.
Accuracy you can check
In piano-verified testing, mp3chords beat the leading converter on root accuracy (91% vs 80%), chord order (79% vs 34%), and chord quality. And every chord is editable if you hear it differently.
Sheets that look like songs
Stanza layout with chords over the right words, on one page — not a multi-page scramble of chord symbols. Export straight to OnSong, ChordPro, Nashville, PDF, or MIDI.
More for less
Unlimited songs on screen for free — no three-song cap. Downloads from $9.99 for a 10-pack, or Pro at $6.99/mo with stems and backing tracks included.
How it works
Upload your MP3
Drag and drop any song — a Suno export, a demo, a recording.
We listen
Stems are separated, chords detected by a transformer model, and lyrics transcribed — you watch each step live, typically 5–10 minutes.
Play
Chords light up in sync with playback. Transpose, add a capo, flip ♯/♭, edit anything, then export in your format.

FAQ
Does it work with Suno and Udio songs?
Yes — any MP3 works. mp3chords was built for AI-generated music first (Suno, Udio, anything you can export as audio), but it handles recorded songs the same way.
How accurate is it?
In piano-verified testing against the leading MP3-to-chords converter, mp3chords scored 91% vs 80% on chord roots and 79% vs 34% on chord order. And if the AI does miss one, every chord is editable right on the sheet.
How long does a song take?
Typically 5–10 minutes depending on song length. You see each real step as it happens — separating stems, detecting chords, transcribing lyrics, aligning everything.
What formats can I download?
PDF, ChordPro (.cho), OnSong, Nashville Numbers, and MIDI. Pro also unlocks isolated stems and a backing track — your song with the vocals removed.
What do I get for free?
Unlimited songs on screen — full chord sheets with synced playback, transpose, and capo. No song cap and no credit card. Credits or Pro are only needed when you want to download.
