Denzel 2025-10-28: extension doesn't work on some websites like rumble.com. Tab capture mode doesn't work either
AkedoNiko 2025-10-27: New version sucks. Used to be fine. The ads to buy premium don't suck as much as you'd think but now pages need to be reloaded constantly in order for it to work. Every time you try to use it, it crashes the page in some form.
Awesome Pikachu 2025-10-26: Good, but doesn't work with google photos
Taryn Janati 2025-10-25: The owner of this extension is engaging in unfair business practices. I've already purchased the pro version of this extension a few months ago. Now, they think that they don't need to honor the terms of that previous purchase because they wrote a couple words about this in the fine print of their terms and conditions. Commonsense counsels that not every business decision that furthers your bottom line in the immediate moment necessarily preserves the goodwill that's needed between the customer and the extension owner, in order for the business relationship to persist over the long term. By placing immediate profits over goodwill, this extension owner has lost a loyal user of their extension for over 5 years. Hope it was worth it!
Alex Fallshaw 2025-10-24: so sick im obsessed. the little slide to make the transition less awkward is crazy
Jaden 2025-10-23: Bought Transpose Pro back in 2017 when the Extension was in its early days. Now apparently I no longer have lifetime access to Pro, and I have to either buy a subscription or purchase again for a lifetime? What happened to my previous purchase which never stated I would lose access in the future or have to pay a subscription?
Tom 2025-10-18: it's so great to sing or try musical pitch, awesome and it's free
Jack Snappy 2025-10-17: Always worked great for me.
Wescley Torres 2025-10-17: I don't usually write reviews, but I've started using the app since google removed all the other pitch shifters somewhere around January because it "doesn't follow best practices". From there until recently, it was amazing and it was working perfectly. I have also noticed that, after this useless update, the extension doesn't work the same way as it used to. At first I was like "Eh, big deal, hopefully they'll fix it immidiately. However as time went on, the extension still has some issues to resolve. If these issues get resolved in the next few days, then I'll give it a higher rating.
Erick Nava 2025-10-15: Was a decent app but now since the update the transpose feature doesn't work anymore
Gordon McLaughlin 2025-10-15: Was a decent app but now since the update the transpose feature doesn't work anymore. If that was put behind a paywall when it was previously free then truly disappointed. As of right now this app is broken after being so good for so long. So look elsewhere until it is fixed.
Käthe Schauer 2025-10-10: Best tool for me as a downtempo DJ! I can pitch everything down before buying tracks. They also have the best customer support – they fixed a bug on request super mega quick <3
The Gamer Lamp 2025-10-08: As of the most recent major update (UI change, paid option, etc.) this extension has been very unreliable with its performance. As of 10/7/2025, when I try to use it, it stops the audio from playing on a video while the video itself keeps playing. I've also been having other issues that other recent reviews have mentioned, such as the extension not opening when clicked on. Also, the +/- buttons won't work until you manually drag the slider to change the pitch/tranpose. I've been using this extension since 2022 and I'd loved it since then. I don't see how a UI update could have caused such a break in this extension that it no longer works. I've tried clearing cache, uninstalling/reinstalling the extension, updating Chrome to the latest version, restarting my device, and none of that has worked. I find this to be a trend where software developers will try to make something "better" but instead end up breaking it or making it worse as per public opinion. And what's also disappointing is that none of the temporary extensions that I've used in the past are available anymore because they don't "follow best practices for Chrome extensions," and the other, very limited, available options are either unreliable or don't work as I want them to.
Danny Vicencio 2025-10-07: Payment for monthly subscription successfully went through, but I am still only able to access the free version! Update: simply logging out and logging back in did not work, but what did work was uninstalling the extension and installing it again.
TonyandKaty Willis 2025-10-05: This extension was great and used it all the time previously. Since the update it refuses to open about 99% of the time. The previous version worked pretty much perfectly. I'd suggest (along with many other reviewers) that the creator goes back to a version that works.
boomkittyFX 2025-10-04: you know what they say, if it aint broke, dont fix it, i hope 6.0.9 actually does fix things, because pitch seems to only last for a short time before going back to lagging behind like it used to, along with that, it sometimes just outright refuses to open on youtube to the point where i have to open it on another tab for it to finally decide to open on youtube. other than that, i highly suggest rolling back the update to what it was before the ui changes, but with the exception of there being advertising for pro mode, which should also be its own individual (though still paid) extension
Ian Irvine 2025-10-04: Has been trash since update. Frequently have to reload the tab. Before update was perfect plugin, never crashed once
P.S.G Official Channel 2025-10-04: I've been using this extension for six years, and have had great experience with it. But when this new update rolled out, the audio started would "crackling" and distort a bit whenever I'd set a value below zero. It works just fine when it set the value above zero for some odd reason, but not when set below zero. Also, the extended transpose only goes down and up to 24 now, rather then 36 originally, as anything -25 and below or +25 and above will play as if it's set to -24 or +24. Not a fan of this new update, they should've kept the extension the way it was before.
kaoru 2025-10-04: I have been using the extension for a year now and had a great experience. It is easily my most used extension. But the new update ruined so many things. I have no idea if it was on purpose to push the new subscription model, or if they are honest mistakes: - In the song history, I could hold up to ~50 songs at a time, and I could delete some to make space for new ones. Now, even if I delete some older songs, there is a chance that picking a new one will delete the older one, even if I am below the ~50 song limit. This is extremely frustrating because I can't listen to a new song out of fear that it will delete a past song and all its saved markers - Transposing from 0 results in a very obvious lag that wasn't there before. Transposing from other values works just fine - I can't use the keyboard shortcuts to transpose while scrolling through my song list anymore - Looping a marker immediately takes me to it. Before, if I looped a marker, it would wait until it reached the timestamp to start looping - Often, it just freezes and refuses to work, then I have to reload the page. Before, the extension rarely had any bugs or issues, it typically ran smoothly as long as my Wi-Fi connection was decent Please give us the choice between the old version or the new one. The old version was perfect and did everything I needed. Until then, my review will unfortunately stay at two stars
Adam Seil 2025-10-03: Was my all time favorite transpose extension up until your new "update." After the update, I have trouble transposing alot of sites. It use to transpose anything you can throw at it... Now it only seems to work on ONLY youtube... I feel incredibly frustrated by this "new update." Please fix to what it was before, it did not need fixing. The auto update proactively made the extension more miserable to work with. Until this is fixed, Im sadly uninstalling.
Josh G. 2025-10-03: Lots of issues since the latest update. Prior to the update, everything seemed to work fine in YouTube Music. But now, I am experiencing the following issues: - A clean install of the extension in Chrome loads the free classic version. At this point, all seems to work as before when playing from YouTube Music. - However, if I log in to try the new paid version, audio becomes extremely distorted (overmodulated), even with all effects off. - When I log back out to try to revert to the free classic version and reload the page, the audio is no longer distorted. But then, if I try to change pitch, the pitch value shows as NaN and no audio changes occur. - Refreshing the page does not fix this. I have to uninstall and reinstall the extension to make it work again. - Also, clicking on the extension button sometimes fails to launch the sidebar. This seems intermittent and difficult to provide steps to reproduce. If these issues are resolved, I will happily update my review.
Brian Ponce 2025-10-03: This new version is barely functional. I would have recommended the old version to everybody, but I can't say the same for this new version, unfortunately. Until any fixes or good changes get made, avoid this version at all costs.
Javier Torres 2025-10-03: The most recent update made the extension hardly functional. It now only works when it feels like it. It was working perfectly fine before the newest update.
Tandemchart6126 2025-10-02: used to be one of the best audio changes until the new update screwed with it now it doesn't work after time even after refreshing it 17 times I will change my review if they fix it or they roll back the update
Qui 2025-09-29: It does what it says. I wish I'd known about this way earlier, for some reason I never thought something like this would exist.
Littlebig Cookie 2025-09-29: transpose good again :)
Ano̸ther Fuckin' Idio̸t 2025-09-29: It's a very nice extension and helps me so much but it's been some days since it doesn't work, is there any fix?
FUWAFUWA MOCHI (FUWAFUWAMOCHI) 2025-09-28: Extension used to be great, but this new pro-update has turned this into an app that will end up killing someone most likely. The sidebar that pops up now rapidly flashes between black and white on my screen for seemingly zero reason whenever I open it. This will trigger a seizure in someone if this is not fixed and possibly kill someone. If you are epileptic stay FAR away from this!
boomkittyFX 2025-09-28: the ui changes are great addons, such as the recent tab showing the settings you've used on it all the way down to the speed set for it, however, the update has also made it run far worse - extension gets incredibly laggy at times - trying to create a new time at a loop resets the time entirely (like trying to change... say a 2:25 marker into a 1:25 marker makes it turn into 1:00 when i type the 1) - extension now opens as a sidebar instead of just a popup window like it used to which makes youtube take more time resizing itself, thus creating more of a slowdown, and it does it again once the sidebar closes - if you accidentally click on the pro trial, you cant go back, as opening the extension prompts you to sign in to access the trial instead of opening up the extension normally, which caused me to enter the trial against my will
Cody Phillips 2025-09-28: Audio on YouTube keeps skipping or flat out not working
Myke Griffin 2025-09-27: I've been using this extension for quite awhile now. I absolutely love it. I did upgrade to the lifetime pro version. Can you do a nice demo video of the new updated version? Thank you.
levelengine 2025-09-27: update is fire
Ruthie Rainbow 2025-09-27: I tried several times to get the pitch-shifting stuff to work, but the pitch still remains the same instead of changing. What happened?
Rifqi Fadhilah 2025-09-27: Hey Developer, Thanks to making this extension, I've been using it for quite a long time, and I must say is impressive tools for listening to music on YouTube or somewhere else, especially the looping feature that always perfect in my ears. But sadly, in this day, I receive this extension new update and my first impression when look the UI is fresh and nice. But that's the only good, the bad thing is, is buggy at MS-Edge, after I log in with account, then the extension using sidebar and flickering like crazy when I play or click the extension, which now is unusable for me to use. And now the second bad thing is the extension is paid, but I already know you developer provided the Classic "Free Forever" one, but again now comes the new problem which is my recent history at this new UI extension, is there maybe you give export history or something like that, because I have plenty recent history at this new extension. And because of the buggy at this point, I have no choice but to use the Classic "Free Forever" one with sadly my history is gone because is different extension. My point was: - Is flickering fast while clicking the extension on MS-Edge (I don't know for another browser) - Consider giving export history or something like for free one (So I don't have to do it all over again from scratch) Thats my reviews so far today, the reason I giving the review is because after the new update I got, I hope you developer can fix the issue, I don't know is just me or anyone need this. I don't care. And Thats it, thanks again for the extension, you really making my day better with this extension. Regards, User.
Brayden Mayer 2025-09-27: New ui is good and the new features are also pretty cool but my issue with this new version is that turning on a loop now skips straight to it and doesn't let the audio get to the loop before starting it, which was the thing i used most. I don't know if I'm either missing something or not but if not, please add a toggle for it at least. Other than that good extension. (Also sorry if i described the issue poorly.)
Daniel Hicks 2025-09-26: Yea this was a decent extension and ever since the update it's been stuttering and even refuse to play the pitch. I've done all of the recommended fixes for the issues, and it's still not resolved.
Sebas 2025-09-26: transpose doesnt start, i press on the extension but it wont start, i tried everything transpose said should fix it, but it doesnt, and yes, i have wifi
Random Guy 2025-09-26: The extension is good, but there is a problem. After 26th september update, the extension no longer opens on my browser, but it open on another browser. Devs, please fix this.
Çınar İnceoğlu 2025-09-23: that is what i wanted. perfectly works
Music Mane School of Fine Arts 2025-09-14: it helps to musicians
Nightshade Wolf 2025-09-11: sounds kinda jittery
Earl Stevens 2025-09-09: An absolutely awesone tool. Really helps my guitar journey!
Bryan Close 2025-09-03: This is a great tool. Easy and intuitive. Incredibly useful. I used to use Amazing Slowdowner, put you have to own the mp3 files to get that to work. Transpose works with anything you're streaming. (I use YouTube Music, and it works great.) Mainly I use it to slow music down to figure out parts, but it's also if you don't want to retune every time you play along with something that wasn't recorded in concert pitch. Here's an example: The Them cover of Baby Please Don't Go, which is tuned about two thirds quarters of the way up fronm E to F. So you can just use Transcribe to subtract 65 cents from the pitch, and the song's back in E standard.
Matthew Charles Heulitt 2025-08-29: 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.
Dawson (DawzDaBozz) 2025-08-24: where has this extension been all my life
Tien Do 2025-08-17: great for play pitch kara video realtime youtube.
Mike James 2025-08-14: This is a must have for musicians!
CHAIWAT SUKASEM 2025-08-14: I'm PAID....
ObjectShowProductions Beta 2025-08-09: 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.
Dave Markham 2025-08-04: 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 :-)
