What FlowSimp is
A browser-based flowchart maker and online whiteboard. Two modes — structured shapes for diagrams, freehand pen for whiteboarding. Drawing happens in the browser. A guest board stays on that device, and an optional account saves boards to the account. FlowSimp is completely free to use — no sign-up required. Details are in the privacy policy.
What FlowSimp isn't
A workspace. A collaboration suite. An enterprise platform with SSO, RBAC, and per-seat pricing. If that's what you need, Lucidchart or Miro are better fits.
