Chrome, Firefox extension that blocks NSFW images using TensorFlow JS

NSFW Filter

A Web extension that filters out NSFW images from websites.

It uses TensorFlow JS- a Machine Learning framework- to check for NSFW images when a web page is loaded.

When a web page is loaded, all the images remain hidden until they are found to be NSFW or not. If they are found to be NSFW, they remain hidden. Otherwise, they become visible.

The extension runs completely on your browser. i.e No user data is being sent to a server for processing.

Read about the release in Hacker Noon or in Towards Data Science .

Model used- nsfwjs devoleped by Infinite Red, Inc.

Guidelines

Edit the background.js , utils.js and content.js files in the /src folder in the root directory and NOT the one in /dist/src .

The contents of /dist/src folder is automatically created when you run npm run build and should NOT be tampered.

The model use for this project nsfwjs is stored in dist/models . This can be changed to use your own models built using TensorFlow JS. You can read the docs from TensorFlow to learn more.

While making changes or adding new files, make sure to add it in the /dist folder and add it to /dist/manifest.json file.
