Releases
Durable software built for daily operation.
CLASSEVE
Research that becomes working software.
We build durable systems, open our experiments, and document the proof. No noise, just exact engineering.
System Architecture.
A clear view of all routes, active builds, and operational policies. Every page serves a specific function.
Releases
Durable software built for daily operation.
Frontier
Active research, unpolished builds, and open technical limits.
Proof
Measured performance, platform stability, and system constraints.
Public
Free, direct utilities that solve a single problem.
Standard
The strict engineering baseline required to issue software.
Signal
Development logs, release notes, and operational updates.
Working Software.
Durable tools built for daily deployment. These are the systems that have cleared our engineering baseline.
Lven Instant
Instant voice-to-text. On your device. Across every platform.
Speak, and the text appears the moment you stop talking — in whatever app has focus, across every desktop and phone. Transcription is instant because it runs on your device. No upload, no round trip, no waiting. We only contact our servers to check your subscription.

earslate
Live speech translation in your ear, on Android.
Walk into a room where nobody speaks your language and hear them as if they did. earslate streams nearby speech through Gemini Live and plays the translation back in your earbuds in real time.

Active Research.
Unresolved problems, experimental builds, and open edge cases. We document our progress and failures in the open.
Lven Web
Browser-based voice transcription without installation.
A web interface for Lven that works directly in the browser. No download, no install. Open the page, speak, copy.
Read frontier detailMeasured Reality.
Documented performance, hard limits, and architectural constraints. Trust requires actual data, not marketing claims.
Five-platform coverage
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.
Transcription is instant
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.
Overlay stays stable across sessions
The floating bubble survives window manager changes, display sleep, and app switching.
Qt6 window flags ensure always-on-top behavior. Position persists across recording sessions.
Local-first recording
Audio is written to disk before transcription. Network failure does not lose the recording.
WAV files persist in the cache directory until transcription succeeds or the user clears them.
Text lands at cursor position
Transcribed text is injected into the active input field at the exact cursor location.
Uses xdotool on X11 Linux, wtype on Wayland, native accessibility on Windows, CGEventPost on macOS, the iOS keyboard text proxy, and Android accessibility service.
Open Utility.
Single-purpose free tools built to solve specific problems, engineered with the exact same standard as our paid releases.
Folio PDF
Free document opener for Android — PDF, Word, Sheets, Slides, and Markdown in one app.

Full access to Lven Instant for 3 days. Card required, cancel anytime.
The Baseline.
The strict performance, stability, and privacy requirements a system must pass before we issue it to the public.
Software reaches release only after it operates correctly under sustained real-world load.
The primary action is obvious within the first minute of use.Failure recovery is engineered before the first public session.
Frontier is where unresolved research lives. We document the work in the open without pretending it is ready.
A direction is established, but technical edge cases remain unresolved.State labels match the current build, not the target build.
Public tools are free, single-purpose utilities engineered to the same baseline as our paid releases.
They solve one specific, well-defined problem.They open immediately, with no onboarding required.
Some builds run correctly but still fail the baseline. Function alone is not sufficient.
Interfaces that hide state behind decoration.Systems that need explanatory copy to clarify their primary function.
Operational Stack.
The external software and infrastructure we rely on daily. No affiliate links—just the exact tools we use to run our own lab.
Linear
The fastest issue tracker we have used. Keyboard-first, opinionated, and quiet. Every CLASSEVE project runs on it.
Trade-off: No free tier for teams. Per-seat pricing adds up.
Warp
A modern terminal that treats the shell as a real interface. Block-based output, inline AI, and fast rendering.
Trade-off: macOS and Linux only. No Windows support yet.
Figma
Still the most collaborative design tool. Real-time multiplayer, component libraries, and dev mode that actually works.
Trade-off: Heavy on RAM. The free tier limits projects.
Obsidian
Local-first markdown notes with bidirectional links. Your vault is plain files on your disk — no vendor lock-in, ever.
Trade-off: Sync is a paid add-on. Mobile app is functional but not fast.
