What it does
It sends only the title, channel and page — no cookies, account identity, watch history, comments or transcripts — and hides recommendation cards before classification so they do not flash.

How you can use it
You can have a developer set up this browser add-on and host an online helper script. The script securely holds an access key connecting the tool to TypeSafe. You can then adjust a slider to choose how strictly videos get filtered.
The tool automatically blocks YouTube Shorts and checks video titles and channel names to hide entertainment. It treats uncertain scores strictly by keeping those videos hidden, revealing only recommendations that clearly meet your chosen threshold.
