Decato

Decato is an agentic interior design app for macOS. Upload a floor plan as a photo, PDF or sketch: Decato reads the walls, doors and windows, zones the space into rooms, and lays out furniture to actual scale, checking clearances and door swings so nothing is placed where it cannot fit. The furniture is real. Decato matches in-stock products from retailer catalogs against the room's dimensions, so every piece on the plan is something a client can order. From the same project you get photorealistic renders of each zone, a priced shopping list and a client-ready presentation with plan, renders, product sheet and budget. It replaces the usual chain of planner, mood board, spreadsheet and slide deck with one workflow. There is a genuine free tier: bring your own Claude or OpenAI subscription and every feature works with no card required. Paid plans add included render volume.
