Requirements

• React Native 0.70+
• iOS 13+
• CoreML enabled environment
• Xcode 10+ Because the model was trained with CreateML, you need Xcode 10 and above to compile the project
• Physical iOS device strongly recommended for accurate inference (Simulator results are unreliable)

Features

• On device inference using CoreML
• Detects NSFW and safe for work content
• Fast and lightweight
• No network calls required
• Works with React Native and Expo native modules
• Simple promise based API

⚠️ Important: Running on the iOS Simulator results in significantly reduced accuracy. For reliable results, always test on a physical device.

Installation

Using npm

npm install react-native-nsfw-detector

Using yarn

yarn add react-native-nsfw-detector

Usage

import { checkNSFW } from 'react-native-nsfw-detector';

/**
 * IMPORTANT:
 * Simulator runs will produce significantly reduced accuracy.
 * Always test on a physical iOS device for reliable results.
 */

async function checkImage(imageUri: string) {
  const confidence = await checkNSFW(imageUri);

  if(confidence > 0.9) {
    console.log("Not safe for work 🤦‍♂️🤦‍♀️")
  } else {
    console.log("Safe! ✅")
  }
}
