Four ways to try our CPU-first speech-to-text before you write a line of code: in your browser, in the cloud, on your desktop and on Android.
Runs entirely inside your browser. The open community model is compiled to WebAssembly and executes on your own CPU. No server, no upload, no install: speak into your mic and words appear in real time, fully offline once loaded.
Try the hosted commercial models right here in your browser. Both streaming (live partials over WebSocket) and pre-recorded (upload a file, get a final transcript with timestamps), with lower latency and higher accuracy than the community model.
A private, on-device desktop app for Mac, Windows and Linux — a CPU-powered alternative to cloud dictation tools and Whisper front-ends. Dictate into any app, add live subtitles to on-screen video and audio, and turn meeting & call recordings into searchable text and summaries — all on your own machine, your audio never leaves it.
Install Kroko ASR Model Explorer from Google Play and run speech-to-text natively on your phone. Record or upload audio, compare model packs by size and accuracy, all processed on-device.
Sign up for the free trial and try Kroko on the hosted API or the on-premise server. Same models, your choice of deployment.
