An app where parents upload photos of their staircase from multiple angles, input measurements, and specify constraints (rental, no drilling, specific railing types). AI analyzes the configuration and returns a curated list of compatible gates with exact mounting hardware, adapter kits, and installation instructions. Premium tier includes video consultation with child safety experts.

Rising housing costs are pushing more families into townhomes, split-levels, and older homes with non-standard staircases. The baby safety product market is fragmented with hundreds of gate options, making selection overwhelming without expert guidance.
