Hey Product Hunt 👋 I’m a solo developer from Japan. I kept running into the same problem whenever I wanted to share videos publicly: faces and license plates were everywhere, and blurring them frame by frame was slow and frustrating. So I built SMART MOSAIC, a native iPhone privacy tool that automatically detects faces and license plates, follows them through a video, and applies a mosaic before you share. It also lets you select any object to track, keep one chosen person visible while blurring everyone else, and make frame-by-frame corrections when automatic tracking needs help. The photos and videos you select are processed on your device and are not uploaded to our servers. The free version may use network access for ads, and purchases use Apple’s services, but your media is not sent to either. I’d especially love feedback on the tracking accuracy and first-time experience. Where did you hesitate, and what would make this useful in your own publishing workflow?
