Code to Flow

Code to Flow is a code-to-flowchart converter that uses AI to create visual diagrams and logic explanations from code snippets in various programming languages.

Code to Flow provides a tool for developers to visualize code structure and logic. Users paste code snippets from any language into the platform, and the AI parses the structure to generate interactive flowcharts, sequence diagrams, class diagrams, or user journeys. It also generates textual explanations of the provided code. The service supports major languages including Python, JavaScript, TypeScript, Java, C, C++, Go, and Rust. Users can edit their diagrams, download them as PNG, SVG, or PDF files, or share them via a link. The tool processes code without storing it, discarding input immediately after generating the diagram.
