Overview

Code to Flowchart is a browser-based tool that converts code into visual diagrams so developers can understand program logic more quickly. It uses AI to analyze pasted code and generate interactive flowcharts, with additional diagram styles available for related visualization tasks.

The site positions the product for individual developers, students, teams, and documentation workflows. It also combines diagram generation with AI explanations, export options, and basic editing so the output can be used for review, learning, or technical communication.

Features

Code-to-flowchart generation

Paste a code snippet and the product turns it into an interactive flowchart so you can inspect control flow and structure visually.

Multiple diagram types

The product supports multiple diagram styles, including flow diagrams, sequence diagrams, class diagrams, and user journey views.

AI-powered explanations

It generates an AI explanation to accompany the diagram, helping readers understand what the code is doing.

Export and sharing options

Export output as PNG, SVG, or PDF, or share a link for review and handoff.

Editable diagrams

You can edit and customize flowcharts after generation, rather than treating the output as fixed.

Ephemeral code handling

The site says code is never stored and is discarded after processing.

Use Cases

Understanding complex code
Use the tool to break down unfamiliar or dense code into a visual path before making changes or debugging behavior.
Learning programming concepts
Convert lessons or examples into diagrams that help learners see how logic branches and steps connect.
Team communication and documentation
Create diagrams for reviews, internal notes, or technical docs when you need a clearer way to explain code behavior.
Multi-view analysis
Generate different diagram types from the same code when you want a flowchart for logic and a class or sequence diagram for context.
Occasional or high-volume use
Use the free tier for small jobs or upgrade when you need higher-volume visualization and no ads.
