The honest answer is that different firms use different tools, and the tools change every few months as new versions launch. At Kingdom & Co., our team uses Claude (with client consent) to capture and document client meetings so no design detail gets lost, ChatGPT for design questionnaires and project documentation, and Gemini for research and material comparison work. We also use AI-supported image generation for concept visuals. The choice of tools matters less than what you use them for: AI is most useful in the documentation, communication, and inspiration parts of the work. The buildable-plan and construction parts are still entirely human.
