Choose Manage Extensions 4. Enable 'PiPifier' 5. Select 'PiPifier' on a website with a video

Build your own keyboard! Touchscreen keyboards don't need to be one-size-fits-all, so let's change that! With Keybuild, you choose the layout, the keys, everything. Keys can be set up to type whatever you want! Letters, greek letters (ɑ, β, ɣ), maths symbols (π, ∫, ∑), arrows (↑→↓←), or even your favourite emoji can be added and organised depending on your needs. Create multiple ‘panes’, each containing keys arranged using a stack-based layout, and switch between them with either an automatic menu, or direct links. Add a small number row to your Qwerty keyboard, or have a try using Azerty or Colemak layouts. Build a keyboard that can keep up with your maths-heavy university course, or specialist profession. Or just make a dashboard for your favourite emoji. Or do all that and more, it's up to you! This app does its best to supports VoiceOver, and accessibility APIs. Technical note: This app is 99% SwiftUI, which is as close as you can get while we wait for the ‘SwiftUI Lifecycle’ to come to Custom Keyboard Extensions! SwiftUI powers this app's advanced functionality, as well as some of its more unusual bugs. :) Disclaimer: This iPad app is available on Apple Silicon Macs, but macOS currently does not support keyboard extensions. Still waiting for that tablet Mac!

Verdict
The clearest difference is price: PiPifier at Free against Keybuild's $3.99. PiPifier also leads on rating (4.4 vs 4.1) and ratings volume (324 vs 49). Keybuild's advantage is in-app purchases (none vs 3). On review sentiment, update cadence, ads and device support there is nothing between them.
