Show HN: Flostep – Diagrams people can actually walkthrough

Flostep is a web-based tool for creating interactive system design diagrams that users can step through visually rather than viewing statically. The platform offers drag-and-drop component creation, labeled interactions, shareable embedded links, AI integration via Model Context Protocol, and collaborative features like comments and notes. It's designed to streamline design reviews, interviews, and architecture planning without requiring accounts for viewers.
