Retail inventory system demo: 8 live apps built by AI models

Every app below is a working retail inventory system, built by an AI coding model from the PlanSmith Retail Inventory Management planner — running, with sample data, not a mock-up. Open one, sign in with the demo account it shows, and try it.

Built by Composer 2.5, Grok 4.5, GPT-5.5 and Gemini 3.1 ProAudited ·
