Instant voice-to-text. On your device. Across every platform.
If your words become text, they should never leave your hands. Lven transcribes locally on every platform we ship — instant, accurate, and entirely yours. The only thing we see is whether your subscription is paid.
View plansLven is a floating voice-to-text overlay that converts speech into text on your device — never on a server. Tap the bubble or press the hotkey, speak, and the text appears at your cursor in whatever app you have open.
It ships on Windows, macOS, Linux, Android, and iPhone. The transcription engine runs entirely offline once installed. Your microphone audio is processed in-process, transcribed locally, and discarded — nothing about what you said is uploaded, logged, or retained anywhere we control.
The only network call the app makes is a periodic check against our subscription API to confirm your account is active. That call carries your account token and nothing else. A cloud-only build of Lven remains available for users who prefer it — see Cloud below.
Real-time voice transcription across Android, Linux, and Windows. This is the experience you get with Lven.
Full access on every platform. No commitment until day four.
Activate free trialEvery word is converted to text locally using a quantised speech model that ships with the app. No microphone audio ever crosses the network. Air-gapped machines work exactly the same as connected ones — minus the subscription check.
An unobtrusive bubble lives at the edge of your screen, hotkey-callable from any app. Tap or press the hotkey, speak, release. Text lands at your cursor through the platform's native input API — no clipboard, no paste.
On Windows, UI Automation places text directly at the caret inside Chrome, WhatsApp, code editors, terminals, and everything in between. macOS uses the Accessibility API; Linux uses AT-SPI2; mobile uses the platform input service. Same behaviour everywhere.
The app periodically asks our API one question: is this account paid? Nothing else moves over the wire. We do not store your transcripts, your audio, or your usage patterns. We cannot — we never received them.
One Lven Instant subscription covers Windows, macOS, Linux, Android, and iPhone. Same on-device transcription engine across all five.
Each platform uses its native audio stack and text injection method. No emulation layers, no shared web shells.
Speech becomes text on your device with no upload step and no network round trip. The result appears the moment you stop speaking.
The quantised speech model ships inside the app and runs on your CPU. No remote inference means no queueing, no rate limiting, and no failure mode where the network is the bottleneck.
Cloud transcription forces a trade between accuracy and privacy. Send your voice to a server and you get state-of-the-art results — but your words pass through infrastructure you don't control, logged in pipelines you can't audit. Keep everything local and you historically gave up speed and quality.
Lven Instant ends the trade. The on-device model is instant — even on a five-year-old laptop — and matches cloud-grade accuracy for everyday speech. No upload, no round trip, no waiting. Your audio never moves. There is no recovery scenario in which an attacker compromising our servers can read what you dictated, because we never had it.
This is the build we ship by default. The original cloud version remains available for users who prefer that trade-off, but Instant is now the standard.
