SponsorBlock is an open-source crowdsourced browser extension that automatically skips sponsor segments and other annoying parts (intros, outros, subscribe reminders) in YouTube videos. It pairs with a server and public API where users submit segment timestamps, using a privacy-preserving query system.

Use cases

• skip sponsor segments in youtube videos
• automatically skip youtube intros and outros
• block subscribe reminders in youtube
• crowdsourced ad skipping for youtube
• self-host a sponsorblock mirror or API
• use sponsorblock with invidious or mpv

When to choose

• you watch YouTube regularly and want sponsor segments skipped automatically
• you want a privacy-respecting, open-source alternative to ad-style blockers for in-video promotions
• you want to contribute segment data or use the open API in your own tools

When to avoid

• you need to block YouTube ads themselves - use uBlock Origin instead
• you need offline video processing rather than in-browser playback enhancement
• you watch on platforms without a SponsorBlock port
