About Code to Flow
Code to Flow is an AI-powered code visualization platform that transforms source code from any major programming language into interactive, exportable flowcharts and diagrams. It analyzes code structure including functions, loops, conditionals, and class hierarchies to generate visual representations that make complex program logic immediately understandable. The tool is privacy-focused with code processed without being stored on servers.
