Question 1

How accurate is NSFWJS compared to server-side AI models?

Accepted Answer

NSFWJS achieves around 90-93% accuracy with its midsized model, which is lower than some server-side solutions like Google Cloud Vision but sufficient for many client-side use cases. It prioritizes privacy over perfect accuracy by running locally without data uploads.

Question 2

NSFWJS or Clarifai for NSFW detection?

Accepted Answer

NSFWJS is better for privacy-focused apps where images stay on-device, while Clarifai offers higher accuracy and more features via API but requires sending data to servers. Choose based on whether privacy or precision is your top priority.

Question 3

How to host NSFWJS model on my own server to reduce bundle size?

Accepted Answer

Download the model files from the GitHub repository, place them in your public directory, and load them via URL in the `load()` function. This reduces bundle size by about 33% compared to using bundled base64 models, as explained in the 'Host your own model' section.

Question 4

Can NSFWJS detect inappropriate content in videos?

Accepted Answer

Yes, NSFWJS can classify video elements by extracting frames, as the `classify` function accepts video elements. However, real-time video processing requires additional implementation for frame sampling and may impact performance on slower devices.

Question 5

What backends work best with NSFWJS for fast performance?

Accepted Answer

WebGPU is often fastest on supported hardware, while WebGL is a strong default for modern browsers. WASM serves as a fallback for restricted environments, but you should benchmark based on your target devices, as noted in the backend selection guide.

Question 6

How to cache the NSFWJS model in IndexedDB for faster reloads?

Accepted Answer

After loading the model, use `model.save('indexeddb://modelName')` to cache it, and load from IndexedDB on subsequent visits. The README provides a complete browser worker example for implementing this caching strategy efficiently.
