Graillon 3 Free Edition

Graillon 3 Free Edition is the best free autotune plugin in 2026. Its pitch correction module is efficient and easy to use, earning Graillon 3 the number-one spot on this list. It is compatible with all digital audio workstations on Windows and macOS. Autotuning vocals with Graillon 3 is straightforward. Place it in your vocal mix channel as an insert effect, turn on the Correction module, and you’re ready. Those who require more control over the pitch correction process can limit the note range to a particular scale, adjust the pitch correction speed, and define the autotune algorithm’s note detection range.

Graillon 3 can sound more or less natural, thanks to its flexible pitch-correction engine. The mix knob on the right-hand side of the user interface can reduce the autotune module’s intensity if needed. On the other end of the realism spectrum, you can pair Graillon 3’s pitch shifter module with its pitch correction algorithm to develop some unusual-sounding vocals. For example, you can mix the dry vocal with the autotuned signal for a unique chorus-like effect.

The developer recently released an updated version of Graillon 3. It features multiple “pitch engines,” which affect how the plugin changes the sound.
