A free online flowchart maker — no signup. Type text and get a live flowchart from text (Mermaid), or draw boxes and arrows by hand — both on the same canvas. It's a real-time collaborative flowchart creator online: share the board URL and everyone edits the same flowchart together, with server-side SVG rendering.
Click the button above and you land on a fresh board with this flowchart already rendered. Two ways to build: edit the flowchart from text in the Mermaid node and it re-renders instantly, or grab the pen and draw shapes and arrows freehand alongside it. This is the exact source the maker opens with:
