Common questions.
Is Lven Instant a Wispr Flow alternative?
Yes. Lven Instant transcribes on your device and types what you said, with no rewrite; Wispr Flow transcribes in the cloud and runs a cleanup layer that decides how the text should read. It also has no caps, runs on Linux, and it is free.
Does Lven Instant clean up filler words?
Yes — ums, uhs, stutters and repeated words are removed, contractions and proper nouns are restored, sentences are cased and punctuated. It does not rephrase, restructure or change tone. The clean-up follows fixed rules: no AI model, no network, the same audio gives the same text every time. The rule list and the golden corpus are published under Research.
Is Wispr Flow private?
Wispr Flow uploads your audio and transcript to its cloud and named processors; what's kept rides on settings you have to trust. Lven Instant's transcription never uploads your audio — there's no retention setting to trust because there's no upload.
Which is cheaper?
Lven Instant is free. Wispr Flow's list price is $15 per seat per month, $144 a year.
Does Lven Instant work on a Mac?
Not today. Lven Instant runs on Windows, Linux and Android, with one account across all three.
