Summaries for your whole feed
Quick answer
Browser extensions and chat with this video tools are useful, but they start after you already found the video and opened it. The expensive part, the hour of scrolling to figure out what's worth summarizing, doesn't change.
What 125x is: 125x is a web app at 125x.app. You connect your YouTube subscriptions, and it gives you a feed of the latest videos from the channels you follow, each with a summary: a verdict, the 5 key takeaways, and the spoiler, plus Actionable and Lessons tabs with more tips. You read that and decide what's actually worth opening.
125x starts from your whole subscription list and sorts everything up front. The summary is the second step.

Summaries
Open any video in 125x and you get a short brief instead of the player. There's a verdict (watch, skim, or skip) with the reason, 5 key takeaways, the things the video tells you to actually do, the lessons worth keeping, and the spoiler, which is the thing the title and thumbnail are teasing, just said plainly.
The verdict tells you which videos deserve your full attention and gives you the gist of the ones that don't.

It can't post, comment, like, subscribe, or change anything on your account. Google's Third Party Data Safety team verified the app on Oct 24, 2026.
If you'd rather not connect an account at all, you don't have to. You can import your subscriptions with a bookmark from your YouTube channels page, or upload screenshots of the Subscriptions tab in the YouTube app. 125x reads the channel names, and the screenshots are processed in memory and never stored.
