Frequently Asked Questions
Is my audio data secure?
Absolutely. BrowserKits uses OpenAI Whisper compiled to WebAssembly (WASM), which runs entirely in your browser. Your audio files are never uploaded to any server - all processing happens locally on your device, making this the most private speech-to-text solution available.
What languages are supported?
Whisper supports transcription in over 50 languages including English, Spanish, French, German, Chinese, Japanese, and many more. It can also automatically detect the spoken language.
Why does the first transcription take longer?
The first time you use this tool, the AI model (~40MB) needs to be downloaded and cached in your browser. Subsequent transcriptions will be much faster as the model is already loaded locally.
