I hope it can automatically add entries to my personal dictionary.

A feature of the competing product, Typeless, is that after voice input is complete, if the user edits the transcribed text using the mouse or keyboard, the edited words are automatically added to the user’s personal dictionary. This way, the system can correct similar words the next time they appear.

I haven’t triggered this feature while using the app yet, but Lightning says they plan to add a feature for automatically adding words to the personal dictionary.
