Chartless
Live chord charts for any song

No song left behind.

Chartless listens to whatever is playing in your browser tab and shows you the chords — live, in key, on the beat. YouTube, streaming, anything with sound. Pick up your instrument and play along. Because every song deserves a little chart.

What it does

A song charter in your pocket. Everything happens in real time, while the song plays.

LIVE

Chords as they happen

A clean overlay shows the current chord, the detected key, and a ribbon of recent chords. A sequence decoder smooths the stream so the display holds steady instead of flickering.

SIMPLE MODE

Made for worship & folk

One tap locks detection to the seven chords of the key (1 2m 3m 4 5 6m ♭7). Everything else is ignored — perfect for songs that stay in one key with steady changes.

NASHVILLE

Nashville numbers

Flip to the Nashville Number System and see 1 · 4 · 5 instead of letter names — the same shorthand session players and worship teams chart with.

BEAT-AWARE

Knows where the beat is

Chartless finds the tempo, shows the BPM, pulses on every beat, and counts the measure — and it trusts chord changes that land on the beat, especially the downbeat, the way a musician's ear does.

INSTRUMENTS

Fingerings included

Chord diagrams for ukulele, guitar, bass, and piano, right in the overlay and the ribbon. Transpose the display up or down to play in a friendlier key.

CAPO ADVISOR

Awkward key? Capo it.

Song in A♭? Chartless says "capo 1 · play G shapes" and draws the shapes you actually finger. The chart follows your capo, not the other way around.

TUNER

A tuner you can watch

A mic-powered chromatic tuner lives in the popup. Single is the classic needle. 3D (Pro) is eight new ways to see pitch — a beat helix that spins until you're in tune, a ball that rolls into a bowl, a Shepard spiral of every note, sand on a Chladni plate. Amber is sharp, blue is flat, green is locked.

STAGE VIEW

Readable from across the room

One tap blows the current chord up to fill the screen — big enough for the whole band, with the beat and key still in view.

SONG MEMORY

Remembers every song

Chartless learns each song's key, tempo, and progression loop — and greets you with them the next time it hears the song. Browse recent songs, jump back to any of them, or link out to a full chord chart on Ultimate Guitar, SongSelect, or Google.

NOT AI

Just math, no AI

Chartless is classic signal processing — the same physics your ear uses, written in code. No AI models, no cloud, no training on your listening, no guessing black box. Fast, predictable, and it works the same on day one thousand as day one.

PRIVATE

100% local

All audio analysis runs inside your browser. Nothing is recorded, nothing is uploaded, no account needed. Your music stays yours.

Why Chartless?

Apps like Chordify are song libraries: you go to them, pick a track they've processed, and read a timeline. Chartless is the opposite — it comes to your music, wherever it's already playing.
