Important
Check the result before relying on it
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.
Practical details
What this Lucaden tool does
Whisper.wasm downloads a quantized OpenAI Whisper model and caches it in the browser, then runs speech recognition locally. The selected tiny model is roughly 31 MB, so the first run needs time and network data.
The original stays unchanged; Lucaden creates a separate result in browser memory.
Included capabilities

- Timestamped segments
- Plain-text export

Questions
About this tool
Is the audio uploaded?
No. The selected audio is decoded and transcribed locally. The model itself is downloaded from its public model host.
Is the transcript guaranteed accurate?
No. Review names, numbers, accents, overlapping speech, and noisy audio carefully.
