Chat across the architecture and place decisions on the tree
Ask anything about your architecture. Mentions become chips you can add as decisions, options, or descriptions on the tree.
Best for: Cross-cutting questions and gap-filling

Switch between Explore, Map, Compose, and Roam anytime in Architecture — chat, mindmap, bulk import, or cross-tree conversation.
