On-device transcription
Speech recognition runs locally on Windows, Linux and Android. No microphone audio ever crosses the network, and once your entitlement is cached it transcribes with no connection at all.
Lven Instant
On-device voice-to-text for Windows, Linux, and Android that types what you said, with the punctuation.
It does not rewrite you, and it does not upload your voice. Speech recognition runs on your own device; account and entitlement checks are separate requests that carry no audio.
Finished enough to ship.
Lven is a floating voice-to-text overlay that drops transcribed speech straight at your cursor in whatever app has focus. Tap the bubble or press the hotkey, speak, and the text appears.
It runs on Windows, Linux, and Android. macOS and iPhone are in internal testing with no public release date. On shipped platforms, microphone audio is processed by the local transcription engine rather than sent to ClassEve for remote inference.
The app downloads and verifies speech-model files during setup or repair. It also contacts the ClassEve API for profile and entitlement checks and refreshes account tokens before they expire. Those requests are separate from the dictated-audio path. Lven Cloud is the separate server-transcribed option.

Choose a planYour words, not a rewrite
A deterministic pass clears stutters and fillers, restores contractions and proper nouns, and adds punctuation. No language model, no network — the same audio always gives the same text, never a rewrite.
Yours to keep after two months
After two months of membership, the app downloads an Ed25519-signed licence. Every build published while you paid keeps working once you cancel — offline, no server, no expiry.
Bubble, hotkey, and text
A bubble sits at the screen edge with a global hotkey. Tap or hold, speak, release. Windows places text through UI Automation and Linux through AT-SPI2, each falling back to the clipboard.
Available platforms are separated from planned platforms
Lven Instant currently publishes builds for Windows, Linux, and Android. macOS and iPhone builds are in internal testing and have no public release date.
The product registry records an exact version, byte size, download URL, and SHA-256 for every available platform. Planned platforms have no artifact or release date.
On-device removes the upload stage, not all latency
Lven Instant performs speech recognition on the device, so its transcription path does not upload microphone audio for remote inference.
Actual completion time depends on the device, model state, audio length, and operating conditions. ClassEve does not publish one universal latency number for all hardware.
We keep it focused on purpose.
Cloud transcription sends audio through remote infrastructure and depends on a working network path. Local transcription reduces that exposure for dictated audio and removes the remote-inference stage, while shifting processing requirements to the device.
Lven Instant narrows the trade. Its on-device model is optimized for responsive everyday dictation: no speech-audio upload and no inference round trip. Because microphone audio and transcript text are not sent to ClassEve for transcription, they are not present in our transcription infrastructure.
Lven Cloud is a separate server-transcribed path for users who prefer cloud processing or whose hardware does not meet the on-device requirements. The two products have different data paths and separate entitlements.

Common questions
What is Lven Instant?
Lven Instant is a voice-to-text app that transcribes your speech into text on your device, in real time, inside whatever app you have open. Press the hotkey or tap the floating bubble, speak, and the text appears at your cursor.
Does Lven work offline and on-device?
Transcription is on-device on Windows, Linux, and Android, so dictated audio is not sent to ClassEve's transcription service. The app still needs network access to download or repair the speech model and to validate and refresh your account entitlement. Offline availability depends on a previously cached entitlement; it is not an unlimited air-gapped licence.
Which platforms does Lven Instant support?
Lven Instant runs on Windows, Linux, and Android today; Android is also public on Google Play, where the listing can sit a release or two behind the direct download. The macOS and iPhone builds are in internal testing and have no public release date. A consumer plan covers up to five active devices across supported platforms.
Is my voice or audio uploaded to a server?
For Lven Instant on Windows, Linux, and Android, speech audio is processed locally and is not included in ClassEve account or entitlement requests. The separate Lven Cloud product is server-side by design: it sends audio to the active transcription provider for processing, and ClassEve does not intentionally retain the audio or returned transcript after the request is handled.
How much does Lven cost?
Lven Instant is covered by the ClassEve membership: $20 a month or $190 a year, with a 3-day free trial, and after two months the builds are yours to keep. Early-access price if you start before 15 October 2026: $10 a month for the first 3 billing months, then $20; or $95 for the first year, then $190. Premium is $59 a month or $559 a year and adds Lven Cloud, priority support and early access. Lven Cloud can also be bought on its own from $3.49 a month billed yearly. All prices exclude tax, which your country adds at checkout.
What is the difference between Lven Instant and Lven Cloud?
Lven Instant runs the transcription model on your device for maximum privacy and speed. Lven Cloud runs it on a server for users who prefer that trade-off. Instant comes with any membership; Cloud is included with Premium, or bought on its own.
