MAutoPitch by Meldaproduction is a free autotune or pitch correction plugin that does the regular pitch correction in your vocals or any instruments. Aside from the autotune feature this plugin also can perform format shift and stereo-expansion.
This plugin might be free but it does have a lot of wonderful features. Regardless of what you want to achieve with this plugin, you can do everything that a paid autotune VST can.
If you are planning to buy a paid one, I would suggest you give this a try before you make the decision.
