Flostep

Flostep is a canvas for how something works — a login flow, a checkout, a service call chain — where the arrows have an order and a viewer steps through them one interaction at a time, the active step lit and the rest faded. Diagrams are built by dragging components or by pasting plain "A -> B: action" lines, or by an AI assistant over MCP. Shared as a link that embeds anywhere as a live diagram, with comments from reviewers who need no account.
