Problem
Too many videos turn out to be an ad, clickbait or simply not what you were looking for, and you only find out ten minutes in.
Solution
A Chrome extension that adds a card to every YouTube thumbnail: views, likes, likes per 100 views and the top comments, read instantly in the browser. One click on Summarize gives a 3–5 line AI summary, a 1–5 worth-watching score and what commenters keep saying. Summaries are cached per video and shared across users, so most of them cost nothing to serve.
The result
Submitted to the Chrome Web Store, in English and Italian. Free with 3 summaries a day, Pro at €4.99 a month for up to 200 a day.
