Show HN: I built a visual AI chat with branching and rich content

I wanted to explore a fresh take on AI chat interfaces by combining a whiteboard, ChatGPT, and dynamic sources.

Why.new is a visual AI chat that lets you branch conversations into dynamic mind maps while offering follow-up questions to keep your exploration flowing. Search for and embed web articles, YouTube videos, and research PDFs directly within the app, creating a rich, interactive space for discovery. It is also fully multiplayer, allowing you to share the link and collaborate with friends in real time.
