Chartless

Live chord charts for any song playing in your tab. No song left behind. 100% local — audio never leaves your machine.

Chartless listens to whatever is playing in your browser tab and shows you the chords — live, in key, on the beat. YouTube, streaming, practice tracks: pick up your instrument and play along. Because every song deserves a little chart. Version 1.1.0 — you asked, here it is The first round of tester feedback came back and most of it was "more, please." So: more. • Bigger memory. The chord ribbon now keeps the last 50 chords, not 8. Tap the expand arrow to see the whole run laid out at once. • Stop means pause, not vanish. Hitting Stop ends listening but leaves the overlay and ribbon right where they are, so you can actually read what just happened. Close it when you're done. • Edit the ribbon. Hover a chord and X it out — mis-hears, false starts, whatever you don't want in the chart. • Export to PDF. One button turns the ribbon into a clean, branded chord sheet. Still 100% local — nothing leaves your machine. • Play it yourself (Pro). New Microphone mode: point Chartless at your own playing and see what chords you're actually hitting. Great for songwriters who play by feel and want to know what they've got. • Try something else (Pro). In Microphone mode, Chartless suggests what to play next — safe moves, brighter lifts, darker shades — with a one-line why on each. • Is this AI? New AI-likelihood meter next to the song title. Chartless reads what the page discloses and listens for a few tells in the audio, then shows a percent — click for the exact reasons. A heuristic, not a verdict, and it runs entirely on your machine. • Fixed: unlocking Pro no longer swaps your instrument to ukulele. Guitar stays guitar. Thanks to everyone who tested. Keep it coming — what's working, what's broken, what you'd pay for. WHAT YOU GET • Live chord overlay — the current chord, big and readable, right on the tab • Key detection — including proper flat spelling (A♭, not G#, in flat keys) • Recent-chords ribbon — see the progression as it goes by • Fingering diagrams — ukulele, guitar, and bass • Beat-aware detection — Chartless finds the tempo and trusts chord changes that land on the beat, especially the downbeat, the way a musician's ear does • Next-chord hints — when the song loops, Chartless learns the progression and tells you what's coming • Lookahead mode — buffer the audio slightly and see chords BEFORE they sound, so your hands have time to move • 50-chord history — expand the ribbon to see the whole run, X out mis-hears, and export a branded PDF chord sheet. One click, still 100% local. • Stop keeps the overlay up so you can read what just played; close it when you're done. • AI-likelihood meter — a heuristic read on whether the song was AI-generated, from the page's own labels and text plus a few audio tells. Click it for the reasons. Not proof — a hint. MICROPHONE MODE (PRO) — CHART YOUR OWN PLAYING Flip the source from Tab audio to Microphone and Chartless charts what YOU play: chords, key, and "next" ideas — safe moves, brighter lifts, darker shades — for songwriters who play by feel and want to know what they've got. The mic is used only while you press Start; audio is analyzed in memory and never recorded or sent anywhere. SIMPLE MODE — MADE FOR WORSHIP & FOLK One tap locks detection to the seven chords of the key (1 2m 3m 4 5 6m ♭7) and ignores everything else. Perfect for songs that stay in one key with steady changes — which is most contemporary worship, folk, and campfire music. Flip on Nashville numbers and see 1 · 4 · 5 instead of letter names, the same shorthand session players chart with. PRO MODE The full chord vocabulary and faster switching for jazz, complex, or fast-changing songs — with an Advanced Tuning panel when you want to tinker. WHY CHARTLESS, NOT A SONG-LIBRARY APP Chord-library apps make you come to them: pick a song they've processed, read a timeline, pay every month. Chartless comes to your music. It works on anything already playing in your tab — livestreams, church services, songs released an hour ago, recordings no library has. Nothing to search, nothing to upload, nothing to wait for. And instead of a subscription, one small price, yours forever. NO AI, ON PURPOSE Chartless is not another AI app. It's 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 private by construction. PRIVATE BY DESIGN All audio analysis runs inside your browser. Audio is captured only while you press Start, analyzed in memory, and discarded. Nothing is recorded, nothing is uploaded, no account needed, no analytics. During use the extension makes zero network requests — the only network call it can ever make is the optional, user-initiated Pro license activation (license key + random install id, nothing else).
