SponsorBlock lets you skip over sponsors, intros, outros, subscription reminders, and other annoying parts of YouTube videos. SponsorBlock is a crowdsourced browser extension that lets anyone submit the start and end times of sponsored segments and other segments of YouTube videos. Once one person submits this information, everyone else with this extension will skip right over the sponsored segment.

You can also skip over non music sections of music videos.

This is open source and the entire database is public.

Некоторые каналы Youtube напрочь игнорируют выделенные сегменты! Например 3 ролика одного канала я указывал сегменты рекламы,но выходит новое видео и блокировки рекламы нет!!!

one of the best extensions that I've added, idk how I've made it this far on yt without this

Funktioniert 1A. Natürlich wird nicht jedes Video markiert aber dies wird ja auch nur durchs taggen von uns erreicht. Also markiert alle fleißig falls nicht schon geschehen und wir haben noch mehr freude mit den tool

Simply brilliant idea and execution.

Best extension of all time.

Самая великая вещь, которая была сделана для Ютуба

Mr. Fox2023年12月12日

I have been using this YouTube ad blocking extension for quite a long time and it does an amazing job. I like that it even detects the in-video self-promotions by content creators and allows you to block those as well. Watching YouTube without this extension sucks.

огонь работает. прям как vanced

I have to admit i was a little skeptical about this, than i try it, and forgot about it, I didn't know why my youtube experience improved so much until i switched and realized that this was the key, it actually changed the experience and the overall feeling for the better, in a way you can't understand until you actually try it, so it's definitely a recommended and a mast have addon. Thank you.

AI product read

Automatically skips sponsored segments, intros, outros, subscription reminders, and other non-content segments on YouTube videos using crowdsourced timestamp data

YouTube videos contain embedded sponsor reads, self-promotion, intros, outros, and subscription reminders that waste viewers' time. SponsorBlock crowdsources segment timestamps so all users automatically skip these interruptions.

Install extension → it auto-generates an anonymous userID → extension automatically fetches known segments for any YouTube video from sponsor.ajay.app server → skips segments in real-time during playback. Users can optionally submit new segments by marking start/end times, and vote on existing segments.

Target users: YouTube viewers who want to skip sponsor reads and non-content segments / Community contributors who submit and vote on segment timestamps / Users who watch music videos and want to skip non-music sections

Source JS files are minified/bundled, making exact line-by-line analysis harder, but key functions (generateUserID, onInstall handler) are clearly identifiable.
The 'subscription' keyword false positive from the heuristic is clearly about YouTube 'subscription begging' segment categories, not paid subscriptions, confirmed by the store description and locale strings.

Monetization

No paid features detected

The extension is fully open source (MIT license per LICENSE.txt files). There are no premium tiers, no payment processing, no Stripe/billing integration, no feature gating. The keyword hits for 'subscription' refer to YouTube 'subscription begging' segments (i.e., creators asking viewers to subscribe), not paid subscriptions. The 'pro' hits are incidental substrings in translated locale strings. The 'upgrade' hit in Persian locale refers to 'The notice has been upgraded!' (noticeUpdate), a UI notice change, not a paid upgrade. There is a voluntary donation link (sponsor.ajay.app/donate) in the help page, but this does not gate any features.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension auto-generates a random anonymous userID on first install (generateUserID() in background.js). This is NOT a login—there is no password, no account creation, no authentication UI, and no server-side account. The userID is purely an anonymous identifier for submitting/voting on segments. The core workflow (auto-skipping sponsors on YouTube) works immediately after installation without any user authentication. The store description confirms: 'When you install the extension, it will generate a random userID that is used when submitting or voting.'
