A pitch coach that runs entirely in your browser. Nothing is uploaded, nothing is stored, and nobody hears it but you.
Hum, sing, whistle — fifteen seconds is plenty. Headphones help.
The gold line is the note you're aiming at. The pale line is you. Where they part company is where the ear hears "off" — and it's almost always a matter of tens of cents, not whole notes.
Three numbers, and only one of them is about talent.
Your keyWhich major scale your singing fits best. It's guessed from what you sang, not assumed — so if you drift into a different key, it notices.
On pitchWhat share of your held notes landed on a note in that scale. Below about 70% and something structural is off — usually the key, not you.
TuningHow far under or over you sit, on average, in cents. A hundred cents is one semitone. Most untrained singers live twenty to thirty cents flat and never know it, because it's too small to name and too large to ignore.
The first real take we ran through this came out twenty-three cents flat against a backing track that was dead on, with 79% of notes on the scale. That singer didn't have a pitch problem. He had a consistent pitch problem — sitting just under the note, all the way through, evenly.
That distinction matters, because a consistent offset is nearly free to fix. You are not missing notes at random; you're hearing the note correctly and landing a hair below it. Once you can see the number, you can push against it — and most people close half the gap in an afternoon.
Auto-tune can also just do it for you. Which is fine! It's fun. But it can only fix flat — it can't fix a note that was scale-correct and simply the wrong choice, and it will happily make a wrong note sound very confident.
The browser tool above shows you what's happening. Actually correcting a recording — separating your voice from the backing, snapping it to the scale, and mixing it back — takes a bit more machinery than a web page. We'll run it for you.
