Lven Instant vs. OpenWhispr
Lven Instant does the setup for you: the speech model downloads, checks and repairs itself, there is an Android app, and one account covers five devices across Windows, Linux and Android — free. OpenWhispr is free, MIT-licensed dictation: you pick and download its local models in the app, or turn on its cloud transcription.
