Code to Diagram Generator
Convert code into visual flowcharts and sequence diagrams for documentation.
Paste code above, then generate to see the Mermaid diagram syntax here.
Reading a function and mentally tracing every branch, loop, and call it makes is possible but slow, and explaining that same logic to someone else verbally is slower still, whereas a visual flowchart or sequence diagram shows the actual control flow and interactions at a glance in a way a written explanation has to build up sentence by sentence. This tool converts code directly into a visual flowchart or sequence diagram, mapping branches, loops, and function calls into an actual diagram rather than requiring the flow to be hand-drawn or described in prose.

Useful for documenting a complex function's control flow visually before onboarding a new team member, generating a sequence diagram of how several functions or services actually interact, or turning tangled legacy code into a diagram that makes its structure visible before attempting to refactor it.
