FAQ

Common questions.

Is Lven Instant a full Dragon replacement?
For dictation — speech into text — yes. For Dragon's voice-command depth (navigating and correcting by voice, custom command grammars), no; pick by which job you need.
Which is more private?
Dragon's v16 desktop editions install locally and need the internet only to download and activate; its Anywhere products run in the cloud. Lven Instant's transcription is on-device by design — audio is never uploaded.
