AI Analysis

●●SolidCozySolve My Problem

Strips clickbait from YouTube thumbnails using YouTube's own storyboard data.

Strengths

•Uses YouTube's native storyboard API—zero external requests, privacy-first approach
•Configurable frame selection (percentage, most-watched, random) respects user preference
•Lightweight, minimal permissions; addresses genuine friction point in YouTube browsing

Weaknesses

•1 user, 0 ratings—no traction evidence; similar extensions (Clickbait Remover, No Shorts) already exist
•Limited scope: only thumbnails; doesn't address recommendation algorithm or doomscroll UX

Post Description

I got tired of clickbait thumbnails on youtube so I created an extension that replaces all thumbnails with a frame from the video. There are options for static percentage or most watched moment.

It's help me avoid a lot of real bad videos, enjoy!
