NSFW Manager

NSFW Manager is a privacy-first Windows application that scans local photo and video folders to detect sensitive or explicit content using fully offline AI models. Nothing is uploaded to the cloud — all classification happens on your device using ONNX-based vision models optimized for CPU and GPU.

Built around a real-life incident (accidentally showing a private photo on a 4K TV during a family slideshow), NSFW Manager focuses on preventing accidental exposure. It is designed for creators, professionals, parents, and privacy-conscious users who want a simple, reliable way to identify and quarantine sensitive media without enterprise complexity.

Local AI Detection

• Fully offline ONNX models
• CPU and GPU acceleration (DirectML, CUDA when available)
• Automatic fallback to CPU
• High-performance scanning

Extensive Format Support Images:

• Standard formats JPEG (.jpg, .jpeg), PNG (.png), BMP (.bmp), GIF (.gif), TIFF (.tif, .tiff), WebP (.webp), ICO (.ico)
• Advanced and raw-style formats HEIC (.heic), HEIF (.heif), AVIF (.avif), DDS (.dds)
• Specialist formats JPEG 2000 (.jp2, .j2k, .jpf, .jpx), portable bitmap family (.ppm, .pgm, .pbm)

Videos (multiples frame extraction): MP4 (.mp4), QuickTime (.mov), Matroska (.mkv), WebM (.webm), AVI (.avi)

Thumbnails: automatic generation and caching for fast preview
