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.

Jamais j'aurais pensé qu'une telle extension soit possible. Merci beaucoup

Арсений Семененко2022年9月23日

идеальное расширение, по мимо основной функции скипа рекламы, оно предлагает скипнуть видео до самого важного момента в видео

Used to be good, but lately they have constant server issues, which means it doesn't work at all...

Thao Duy Nguyen2022年9月20日

Excellent work

k t2022年9月19日

the blocking feature works like a charm but sadly i can never submit any new sponsor segments as the servers are always down. i keep getting 502 errors no matter how long i wait.

Отличное приложение, но есть проблема! За 3 года частота ошибок сервера резко упала. Здорово. Но на панели видеоплеера, меня уже заебала кнопка *id="infoButton" class="playerButton ytp-button autoHiding sbhidden" title="Открыть всплывающее окно SponsorBlock"*. У меня есть другое расширение, что создает рядом кнопку, а когда пытаюсь навести курсор на нее, выскакивает ваша кнопка "Спонсор блока". Нахрена такое делать? Дайте возможность эту хрень отключить, буду вызывать только с панели расширений. Тогда верну отзыв на 5 звезд.

Had it for a long while, it is a must these days with youtubers shoving in sponored ads in middle of videos and with the skip to highlight feature is just amazing.

Самое лучшее расширение!! огромное спасибо разработчикам!

Rudo Halmi2022年9月16日

I'm paying for YouTube premium, and I don't care about who's is sponsoring which video. AFAIK I'm sponsoring their videos by watching them. So this extension is a huge time and nerve saver. I'm just sorry I didn't find it earlier :)

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.'
