A vocal tuner (autotune) detects the pitch of your singing and corrects off-key notes toward the nearest semitone or scale note. This tool runs the pitch detection and correction entirely in your browser using real-time DSP - no model download needed.
Choose your tuning mode: snap to the nearest semitone for natural polish, or lock to a musical scale (major, minor, pentatonic). Adjust the strength from subtle correction to the full robotic T-Pain effect.
Yes - completely free, no model download, unlimited use.
No. All pitch detection and correction happens locally in your browser.
The hard-tuned robotic voice from the 2000s - set strength to 100% and snap mode.
