Why this tool is useful
Capture a product walkthrough, presentation or reproducible bug report without uploading the recording to YTSave.

Record a user-selected screen, window or browser tab locally with optional shared audio and microphone input.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
Capture a product walkthrough, presentation or reproducible bug report without uploading the recording to YTSave.
The browser permission chooser supplies the selected display stream; MediaRecorder encodes supported WebM media into bounded in-memory chunks.
Choose one browser tab, enable tab audio if needed, record the demonstration and download the resulting WebM file.
Browser capability and explicit capture permission are checked before recording starts; unsupported sources fail without producing a file.
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.
