About NSFW Filter
NSFW Filter is a free, open source, and privacy-focused browser extension to filter out "not safe for work" content.
Under the hood, NSFW Filter uses an AI model to detect NSFW content and block it.
With the v3.0.0 release, we bring a better, faster model and a completely new look. To learn more: https://nsfwfilter.com/news/v3.0.0
This project is completely built by volunteers and will be forever free and open source. To contribute to the development of the project, visit: https://github.com/nsfw-filter/nsfw-filter
