Pitch detection in your browser. No app, no install.
Sing or play a note and we’ll tell you what it is and how in-tune.
Audio stays in your browser. Nothing is sent anywhere.
Allow microphone access, play one steady note, and watch the detected note, octave, frequency, and cents offset update in real time.
When the reading is within five cents of the target pitch, the indicator highlights it as in tune.
Audio is analyzed locally in your browser and is not uploaded.
For a steadier reading, tune in a quiet room and play one clear, sustained note at a time.
