Hey Product Hunt 👋 I sell Data & AI for a living. Which means I spend a lot of my week verbally walking people through architectures. "So the leads come in through HubSpot, marketing qualifies them, they get routed to an SDR, and meanwhile everything's syncing nightly into Snowflake where dbt cleans it up before it hits Tableau." By the third sentence, half the room is gone. Nobody can hold a flow in their head while you describe it. And nobody wants to stop the conversation to open Lucidchart and start dragging rectangles around. So I built Wavelength. You talk. It draws. Hold the mic, describe your process out loud, and it builds a real editable graph: actors as cards, systems as hexagons, data stores as cylinders, decisions as diamonds. Or paste a call transcript and get the same thing. Then edit it however feels natural to you: ask AI in plain English ("add a QA step after intake"), right-click a node, or open the inspector. The hard part wasn't the transcription. It was getting the AI to produce a graph that matches what you actually said. Early versions would hear "Marketing qualifies the lead" and emit two nodes, a Marketing node AND a Qualify node, then tangle every parallel path together into spaghetti. Took a full rewrite of the structuring logic plus a deterministic dedupe pass to get one node per entity with the verbs living on the edges. That single change is what took it from demo-toy to something I actually use on calls. Free tier is 5 flows, no card. Would love to hear what breaks it, especially if you describe processes that look nothing like sales pipelines. Mitchell
