FrankenMermaid

FrankenMermaid is a private native Mermaid diagram workbench for iPhone and iPad. Write Mermaid source beside a live diagram, start from a searchable gallery covering 24 diagram families, or import an existing .mmd, .mermaid, or plain-text file. CREATE AND REFINE DIAGRAMS Edit source with syntax-aware presentation and watch the bundled Rust and WebAssembly renderer update the graph on device. Tune the diagram theme, rendered text size, shadows, gradients, corner radius, and canvas spacing. INSPECT THE ACTUAL GRAPH Open the native inspector to read the engine-authored semantic description, parser diagnostics, node and edge counts, and exact source bindings. Select a rendered node, edge, or cluster to inspect its source range and apply a bounded exact edit through the engine source lens. EXPORT REAL FILES Share Mermaid source, scalable SVG, 2x PNG, PDF, or a self-contained animated HTML page. The share flow creates a file representation suitable for Files and other document destinations. PRIVATE BY DESIGN The renderer, samples, and working data are bundled. Diagram source and output stay on the device unless you explicitly choose to share a file. No account, remote rendering service, analytics, or network connection is required.
