Most diagramming tools make you drag boxes. Wavelength listens instead. Talk through a data flow, or drop in a call transcript, and it builds an editable graph of the actors, systems, decisions, and data stores you described. Then edit by voice, plain-English AI prompt, right-click, or inspector. Built for tech sellers and solution engineers, where verbally describing an architecture loses the room in seconds. Version history, team workspaces, PNG export. Free to start.
