A phonetic Arabic keyboard I created maps English letters to Arabic sounds, covering emphatic letters, hamza, and diacritics—making it easier for learners and casual users to type Arabic.
Reminds me of Yamli (https://www.yamli.com/arabic-keyboard/) which lets you type in English and transliterates it to Arabic. For example you type habibi and it transliterates it to حبيبي.
Windows used to have one that acted as a system keyboard. Funny thing is, if my memory is correct, the official website for it was a silverlight application, so it didn't exactly survive archiving either https://web.archive.org/web/20091228203449/http://www.micros... the msi download works though.
