SponsorBlock is an open-source crowdsourced browser extension to skip sponsor segments in YouTube videos. Users submit when a sponsor happens from the extension, and the extension automatically skips sponsors it knows about. It also supports skipping other categories, such as intros, outros and reminders to subscribe.

It also supports Invidious.

Server

The backend server code is available here: https://github.com/ajayyy/SponsorBlockServer

To make sure that this project doesn't die, I have made the database publicly downloadable at https://sponsor.ajay.app/database (License). If you are planning on using the database in another project, please read the API Docs page for more information.

The dataset and API are now being used in some ports as well as a neural network.

API

You can read the API docs here.

Building

See CONTRIBUTING.md

Credit

The awesome Invidious API was previously used, and the server is now using NewLeaf to get video info from YouTube.

Originally forked from YTSponsorSkip, but very little code remains.
