Ready. Your working data stays in this browser.
Record tutorials and presentations where viewers need both the shared screen and the speaker's camera in one downloadable file.
A local canvas composites the permitted display and camera streams frame by frame; browser audio tracks are mixed locally before MediaRecorder starts.
Share a presentation tab, permit the webcam and record a picture-in-picture lesson without sending either stream to a server.
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
