Why look for an alternative to Transpose?
Transpose is one of the best-known extensions for changing the key and the speed of a song in your browser. Its free version covers pitch, speed and loops on every song. But its Studio tools, such as the equalizer, the Vocal Reducer, Stem Mix and clips, are only free on 3 songs at a time, and you can swap one of them every 30 days. Saving a song's settings also requires a Google account and one of those 3 songs.
Beyond that, Transpose Studio costs $4.99 a month, $34.99 a year or $149.99 one-time (prices on transpose.video, November 14, 2026).
If you practice more than three songs, that limit comes quickly. KeyPitch takes the opposite approach: every feature, on every song, for free.

Everything KeyPitch does, for free
All of this is free as soon as KeyPitch is installed, on every song, with no limit.
Key, speed, pitch and reverb in real time
Move the Semitones slider from −12 to +12 to put any song in your key, slow it down or speed it up from ×0.25 to ×4 without changing the pitch, fine-tune the pitch from 415.3 to 466.2 Hz to match your instrument, and add up to 100% reverb. Everything changes while the music plays.
3 A/B loops to practice the hardest passages
Set up to 3 A/B loops on the same song, for the verse, the chorus and the bridge, and switch from one to another in one click. Infinite repeats the passage until you have it; Single plays it once and waits. Keyboard shortcuts: A, B, L, and 1, 2, 3 to pick a loop.
A 10-band equalizer with 6 presets
Shape the sound from 32 Hz to 16 kHz, band by band, or pick a preset in one click: Bass, Vocals, Treble, Warm, Bright and Loudness. Vocals brings the voice forward to learn a melody; Bass brings out the bass line to transcribe it. In Transpose, the equalizer is a Studio tool.
Save your settings as presets in the library
When a song sounds right, click Save current: its key, speed, pitch, reverb, 8D audio, equalizer and A/B loops are saved together, like a preset. Sort your songs into folders, one per student, band or set, and reopen any of them in one click, exactly as you left it. No account needed: your library stays in your browser.
Track your progress with your practice stats
The My space tab follows your practice: current streak, best streak, practice time over the last 7 days and in total, songs practiced and active days, with a calendar of the days you practiced. Watching your streak grow is the best motivation to practice every day.
Studio mode: everything next to the video
Click Studio mode and KeyPitch opens in Chrome's side panel, right next to the video, while YouTube switches to theater mode. The video on the left, every control on the right, and nothing covering the picture.
On YouTube, Spotify, Apple Music and more
KeyPitch works the same way on YouTube, YouTube Music, Spotify, Apple Music, Deezer, Amazon Music, SoundCloud and Audiomack, and your library keeps your songs from every site side by side.
100% free: no subscription, no in-app purchases
With Transpose, using the Studio tools on more than 3 songs means paying. With KeyPitch, everything is free, on every song, for as long as you want: no trial period, no song limit, no credit card and no account.
- Key, speed, pitch, reverb and 8D audio
- 3 A/B loops per song, Infinite or Single
- A 10-band equalizer and 6 presets

How can it be free? KeyPitch also offers an online Audio Studio with paid options, such as downloading your transposed songs. The extension is how we welcome musicians, and its developer has promised it will always stay 100% free.

Several users compare KeyPitch with Transpose in their Chrome Web Store reviews. Here is what they say, in their own words.
sooo much better than transpose yo thanks for making this
LOVE LOVEEEE THIS EXTENSION AND IT'S FREE TOO🥺🥺🥺
Absolutely fantastic app much better than the now paid Transpose. I would love to see a couple of features added, such as: - HQ Audio - Vocal Reduction - EQ Mixing Above all else, though, and if you take anything away from my review, please make it so that we can assign a tab to the extension. That way, if I'm looking at lyrics on a different tab, I can quickly change the transposition/pitch without having to go back to YouTube.
Comparably better than the previous plugin I used for a purpose like this, you don't need to refresh every time you make a little adjustment, it all works fluidly in real time, same of course applies to effects and such! low memory footprint, and honestly I adore just how well thought out and designed the UI/UX are here, alongside the fluidity of the controls, it all feels natural and while I'm sure this can be expanded on further, as it stands, this has a 4.9 out of 5 for a reason- this is a solid extension.
easy to use, practical and free
Translated by KeyPitch · original language: EspañolSuperb app, very effective. I sing, and it's indispensable for adapting songs to my vocal range, for working on my high notes, for example, and for seeing my progress. Really well done and thank you!
