- (2025-08-29) Matthew Charles Heulitt: I use this daily with my guitar students. We slow stuff down, loop sections or licks, tune songs that are off-pitch. It's a practicing game-changer. I link it in everyone's practice notes and encourage them to download it TODAY.
- (2025-08-24) Dawson (DawzDaBozz): where has this extension been all my life

- (2025-08-09) ObjectShowProductions Beta: Love the extension and all, however whenever I were to screen record the pitch does not stay consistent and the audio seems to sound a bit distorted. I kinda figured out what went wrong so I removed the extension and re-installed it, cleared my cache, disabled other extensions, but for some reason it's still acting like this. Unfortunately there are no better alternatives (and especially free versions) than this, so I just simply need to work my way around and deal with it.
- (2025-08-04) Dave Markham: Works very well. Convenient for learning and practicing music when I'm away from my other (better) equipment. I've loaded this on all my computers :-)
- (2025-07-29) Hayden Kinsman: This is my favourite extension on Chrome, especially as a full-time musician. Being able to transpose media including YouTube and Spotify is invaluable for practicing. I'm so appreciative of this beautiful extension and incredible functionality.
- (2025-07-25) Mehmet Sarlar: Finally I can listen Blue System - Under My Skin with a higher pitch! (I'v been listened the YT video of Blue System's Magic Symphony concert that performed in Russia and I liked it cause of the higher pitch rather than the original video (Peter's Popshow video) and I searched for a extension like this to listen the Blue System's Under My Skin with a little bit higher pitch and I've found this one) Thanks for the extension!
- (2025-07-23) Richard Reynolds: The perfect extension for playing in different keys. Thanks!

- (2025-07-16) Sportytrainguy: It was working well up till recently where after playing a song, I would have to refresh the page every time I wanted to repeat the song since the pitch shifter breaks.
- (2025-07-14) Mark Webster: Phenomenal app. I use it to slow down songs for learning guitar and harmonica solos. I can loop individual phases until I get it down and then move on to the next until I'm playing the whole solo. Cuts down the learning time dramatically! I use backing tracks as well but this is quick and convenient and backing tracks aren't always available. Thank you!
- (2025-07-14) Emerson Yair: Genial
- (2025-07-10) Tom A.: Love the transpose feature, it makes songs sound brand new!
- (2025-07-10) HALAL: It's good and all but it could've been better if you could keep the pitch at what you wanted.
- (2025-07-05) GRG: I don't know what happened, but this extension recently started causing issues with my YouTube, making it extremely laggy and nearly unwatchable. I had to disable the extension to get it to stop lagging. I have a good internet connection. Please fix this!
- (2025-07-04) Janet! Kane: Love this! I am able to sing all the songs that were out of my vocal range and don't have to worry about straining or hurting myself. What a brilliant thing and super simple to use. Donate & buy them a cup of coffee -well deserved!

- (2025-05-24) Alex Sannikov: Invaluable for practicing any piece of music! You can effortlessly slow music down to a speed you are comfortable and gradually build up the speed. I love that you can loop between two timestamps so you can easily focus on one segment of the song without having to manually futz with the music player. I've found this works seamlessly with YouTube and Spotify in the browser.
