NSFW Filter

An npm library that helps filter out inappropriate images using AI.

---

Installation

npm i nsfw-filter

Usage

import NSFWFilter from 'nsfw-filter';

const isSafe = await NSFWFilter.isSafe(image);

Full example

import { useState } from 'react';
import NSFWFilter from 'nsfw-filter';

function ImageUploader() {
  const [imageUrl, setImageUrl] = useState('');

  const handleImageUpload = async (event) => {
    const file = event.target.files[0];

    // Check to see if the image is appropriate
    const isSafe = await NSFWFilter.isSafe(file);
    if (!isSafe) return 'Image is not appropriate';

    // Process the image if it is safe
    if (file) {
      const reader = new FileReader();
      reader.onloadend = () => {
        setImageUrl(reader.result);
      };
      reader.readAsDataURL(file);
    }
  };

  return (
    <div>
      <input type="file" onChange={handleImageUpload} />
      {imageUrl && <img src={imageUrl} alt="Uploaded" />}
    </div>
  );
}

export default ImageUploader;

Real world usage

nsfw-filter is currently used in production to process hundreds of thousands of images for a popular image restoration service called restorePhotos. It helps prevent people from uploading inappropriate pictures. See how it's used here.

How it works

This library uses both Tensorflow.js, an OSS library for machine learning models, and nsfwjs to predict whether a given image is NSFW (Not Safe For Work).
