Face Detection Photo Editor (Glasses/Stickers)

A client-side web tool that automatically detects faces in images and applies customizable overlays (glasses, stickers, effects) with precise positioning. Users upload photos, the tool finds faces using ML, and they can tweak placement and styling. No backend = privacy-friendly and fast.

Face detection in the browser has become genuinely viable thanks to MediaPipe and TensorFlow.js reaching maturity, so the client-side angle is real and not just a marketing claim. Snapchat's AR filters and PicsArt dominate the mobile side, but there's no clear incumbent owning the lightweight, privacy-first web version for creators who want a quick batch-edit tool without installing anything. The $200–1.5k/mo ceiling reflects the core problem: this is a novelty utility, and converting free users to paid is brutal when the use case is "slap sunglasses on a photo for a meme." The most likely failure mode is that people just use Canva's sticker tools or a phone app and never return, leaving retention too low to build any recurring revenue.
