JevMade field notes / Written guide

Filter a video feed with one narrow question

FocusTube is a browser extension that hides YouTube Shorts and recommendations that do not look useful for focused learning. Instead of asking a model to rewrite the page, it asks one yes-or-no question about visible video metadata and reveals only results above a chosen probability.

Our summary

FocusTube gives the viewer a cutoff they can adjust and a way to reveal hidden cards. Its one yes-or-no question judges whether each visible recommendation appears useful for focused learning, rather than asking a model to rewrite the YouTube page.

The extension sends the video title, channel name, and whether it appeared on the home page, search results, or watch recommendations. It groups up to twenty videos per request. A Cloudflare Worker forwards requests while keeping the secret key outside the browser. Saved results last seven days.

These details leave the browser for an external service, but the model never sees the actual video. Short titles and uncertain probabilities can hide useful material or show distractions. The controls let viewers restore hidden videos, but they do not prove that the filtering is accurate.

Key takeaways

Ask one clear question about a recommendation's relevance.
Reuse saved judgments and let viewers adjust the cutoff.
Explain which video details leave the browser and that Jev never watches the video.
