Picture holding a key and dictating a paragraph directly into the editor you already use. Ubuntu 26.10’s Myna preview offers that workflow by sending the resulting text to the app with focus.
Canonical says the speech recognition runs on the device and can work offline after you install the required models. The Ubuntu release notes describe Myna as an early preview that you install separately.
What happens to the text depends on the app where you dictate it. If that app syncs documents to a cloud account, the text can still leave your computer through the app’s normal sync.
