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.

Upload your MP3 — freeUnlimited on-screen songs. No credit card.

Accuracy you can check

We use a multi-method pipeline that cross-checks chord,\n key, and lyric timing across the audio, then lets you\n fine-tune anything by ear. Most accurate on worship, folk,\n pop, and singer-songwriter — every chord is editable if you\n 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.

Free while we tune it

Unlimited songs on screen for free — no song cap, no credit card. We’re still improving chord and lyric accuracy, so downloads are switched off while we work through the reports we get back.

How it works

1

Upload your MP3

Drag and drop any song — a Suno export, a demo, a recording.

2

We listen

Stems are separated, chords detected by a transformer model, and lyrics transcribed — you watch each step live, typically 5–10 minutes.

3

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?

We use a multi-method pipeline that cross-checks chord, key, and lyric timing across the audio — then lets you fine-tune anything by ear. Most accurate on worship, folk, pop and singer-songwriter; less reliable on jazz or classical.

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. Downloads are switched off while we work on accuracy — everything on screen is free and exportable once they’re back on.

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. Paid plans (credits for downloads, and Pro with stems and backing tracks) are listed below but are not on sale yet.
