NSFW Filter

NSFW Filter - Content Protection

AI-powered NSFW content blocker. Real-time protection from pornography, hentai and explicit images.

🛡 NSFW Filter is a powerful Chrome extension for automatic blocking of unwanted content (NSFW) in real-time using artificial intelligence.
Protect yourself and your family from unwanted explicit content while browsing the web. NSFW Filter uses AI to automatically detect and block inappropriate images — right in your browser.

✨ Key Features:

🔒 Real-time Blocking
Images are checked instantly as pages load with no browsing delays.

🚀 WebGPU GPU Acceleration
GPU-accelerated classification without unsafe-eval. Automatic CPU fallback if WebGPU is unavailable.

🧠 Model Selection
• MobileNet v2 — fast model (2.6MB), ideal for everyday use
• InceptionV3 — accurate model (22MB), maximum recognition quality

🎚 Adjustable Sensitivity
Flexible slider from 0% to 100% lets you fine-tune filter strictness:
• 0% - Soft mode (blocks only explicitly graphic images)
• 50% - Balanced mode (recommended for everyday use)
• 100% - Strict mode (maximum protection)

📊 Content Categories:
• Pornography
• Explicit content (Sexy)
• Hentai and anime 18+

📈 Detailed Statistics
Track the number of blocked and scanned images in real-time.
