Lven Instant
Private voice to text. Runs on your device; your voice never leaves it.
The most private speech to text there is. The model runs on your own device, so your voice never leaves it — and it types exactly what you said, six times faster than you speak.
Your voice never leaves this computer.
Not a promise — a wiring diagram. Everything that touches what you said happens inside the machine in front of you.

Whatever microphone the machine already has. The app opens it, reads frames, and hands them on in memory.
Speak. See it type.
Voice to text as you speak, on Android, Linux and Windows. This is Lven Instant.
It tidies your punctuation. It never puts words in your mouth.
The clean-up follows fixed rules, not AI, so all of it fits in a set of test sentences. Here they are — all 31, compared word by word in your browser. Drag the handle to run the pass by hand.
guard“you know like you know” stays. It is not in the filler list, and the pass does not judge whether a phrase is worth keeping.
All 31 cases pass on every commit, on every platform, with zero words invented. The corpus, the counts, and how to run it.
The text is already there when you stop talking.
Set how long you speak. Each engine then runs at the speed it was actually measured at on the same consumer-grade hardware. Anything still going past the speech ends line is one that keeps you waiting after you have stopped talking.
