Try Jachnun

English dictation that gets the Hebrew words right. Say a sentence with a Hebrew word in it and Jachnun writes it down, right here on your device. Nothing to install, and your audio never leaves it.

Large downloadThe model is about 660 MB. Your browser downloads it once, then keeps it. Best on a desktop or laptop in Chrome, Edge or Firefox; once loaded it uses about 2.5 GB of memory.

On a phone, the Hebrish app is the better way to try it: the same model, offline, as a keyboard.

The Hebrew word should come out in Latin letters, spelt as shown. The Hebrew script is only a reference; the model never writes it.

Every word it was taught: the lexicon.
