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
The browser decodes the video's audio track and Whisper.wasm creates timestamped text on your device. Codec support depends on the browser; Lucaden's media converter can create a compatible audio file when needed.
The original stays unchanged; Lucaden creates a separate result in browser memory.

Questions
About this tool
