• (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.

• (2025-04-01) Fernando P: As a musician i love this. I can practice singing, or experiment a listen to songs in different pitches. I don't have to download the video or any softwares to my computer, and i dont have to wait for this to process the shift changes. Literally instant! And when you come back to the video later, the pitch is reset how ever it saves the settings from last time for that song for you to quickly use. simple and versatile. Well done.
• (2025-04-01) Fernando Palacios: Free. simple to use. and straight to the point extension! This was the perfect solution for me. Didnt have to download any software or upload any files, literally a few clicks of a button and done. I usually dont write reviews but I am satisfied.
• (2025-03-31) Marie-France van Oorsouw: Excellent app!
• (2025-03-29) Seth Bo Nelson: Transpose is a very helpful Chrome extension that lets you change video speed, pitch, and loop sections — which is perfect for music practice, language learning, video study, and more! I really like how easy it is to use and how well it works with sites like YouTube. But I’m giving it 4 stars instead of 5 because there’s a lot more potential to expand and improve the experience for families, students, and everyday users. Here are my detailed suggestions: 1. Add an AI Censorship Mode (Like a Family Filter): Please allow users to mute or skip bad language or adult content while watching videos. Just like TV edits or parental controls, this feature could: Automatically bleep out or mute offensive words Skip inappropriate sections in videos Use an AI to scan subtitles or audio in real time You could even let users choose their filter strength, like: Mild Mode (just removes profanity) Kids Mode (removes anything not child-safe) Classic TV Mode (like edited movies that air on Hallmark or TBS) Custom Mode (users can pick words or scenes to block) This would make Transpose the perfect extension for classrooms, families, and safe viewing anywhere! 2. Combine with TV/Radio Broadcast Versions: Add a feature where users can switch to TV-style versions of movies or shows — like the edits made for: Disney Channel ABC Family Cartoon Network TBS FX This would bring back that classic “clean TV version” style many of us grew up with, but on YouTube or streaming platforms! 3. Save Custom Speed & Pitch Settings Per Video: Let us save different speed/pitch settings for each video and name them — like “practice mode,” “fast watch,” or “clean version.” This would help musicians and learners a lot. 4. Add Keyboard Shortcuts for Loop Controls: It’d be amazing if we could start/end a loop, pause, rewind, or reset speed with custom keyboard shortcuts. 5. Sync with Streaming Services & More Sites: If possible, please expand support to: Netflix Prime Video Disney+ Hulu YouTube Kids Vimeo Podcasts Audio/Video files uploaded from our computers This would make it more universal and powerful! Final Thoughts: This is a fantastic tool for learning, watching, and practicing, and it deserves 4 stars. If the developer adds AI censorship, filter modes, TV-version switching, and more platform support, this extension will be a must-have for families, educators, and content lovers of all kinds. Keep it up — can’t wait to see where this extension goes next! – Seth Bo Nelson
• (2025-03-28) Tuah Afriadi F.: was cool
• (2025-03-24) DEREK KRISTIANSON: I use Music Speed Changer on my tablet, and couldn't find one for my PC until now, Great extension, Love it, Good Job Guys. nice that I don't have to have all the songs downloaded to use this 5 stars all the way!!!!
• (2025-03-22) Erdal Bora: Very easy to use, and immediately worked. I love it.
• (2025-03-21) Vishnu Kumar: so good
• (2025-03-20) Ido Weiss: Very useful in learning new tunes, both for slowing down and practicing in different transpositions
• (2025-03-13) Asif Mahbub: Thank you so much!! Life saving plugin. Was anticipating for something like this to be made for years!
• (2025-03-11) Evil Kermit21: it's pretty compressed, but it works fine for my purposes. Glad there is a setting for keeping the speed and pitch changes but I just wish it sounded smoother
• (2025-03-10) Gustavo R.: Great extension for singers....
• (2025-03-10) adiel: Is there a way i can download what I've adjusted?
• (2025-03-10) Porter Sutton: It works great awesome extension.
• (2025-03-06) Gideon Quinones: Like Maya McCain says, it delays when I use the shifter, especially when I pause or unpause the video. Could you fix it? Please?
• (2025-03-05) Jason Bratcher: I actually wish this also had proper playback rate adjustment (speeding up/slowing down) on an analog vinyl record/cassette tape?
• (2025-02-26) John Clark: I use this extension all the time with my students. It is so useful to be able to slow down songs to a tempo that meets them where they currently are and then bring them up to full tempo. And it's so much more fun playing with an actual song or backing track than a metronome. I had been looking for something like this for a while. So glad it exists!
