NSFW Filter

A free, open source, and privacy-focused browser extension to block "not safe for work" content.

Images are classified on your device with TensorFlow.js. Nothing is uploaded, and no data leaves your browser.

NSFW Filter ships two models you can switch between in the popup: a small, accurate Vision Transformer (ViT-384) that classifies images as safe or not safe (the default), and the original NSFWJS MobileNet model.

Download now for Google Chrome.

Usage

You can install the extension from the Chrome Web Store or source.

When you load web pages, NSFW Filter will first hide all images and only show those classified as safe.

Click the icon in your extensions tab to open the popup. From there you can turn protection on or off, adjust how strict the filter is, choose how flagged images are handled (blur, grayscale, or hide), pick which model does the classifying, and allow specific sites.

Development

Install dependencies by running:

npm install

Then build the project:

npm run build

To run the tests:

npm run test

To develop with live reload, start a watch build that rebuilds on every change:

npm run dev

Then, in a separate terminal, launch Chromium with the extension loaded. It reloads automatically as the build updates:

npm run start:chrome

To load the build manually instead, open Google Chrome and open the Extensions page by navigating to chrome://extensions or by opening Settings and clicking Extensions from the bottom left.

Enable Developer Mode by clicking the toggle switch.

Click the Load Unpacked button and select the extension directory (.../dist).
