Decato replaces the interior designer. Not the taste: the month of work and the markup. Drop in a floor plan or describe the room; our own model reads it to ±10 cm. Name a budget and an agent furnishes every room from real products that fit, checked against your walls before anything lands. Every piece rendered at its exact size, no hallucinated furniture. Out: a purchase order, not a moodboard. Free for Mac on your own ChatGPT, Claude or Gemini key.
