Coddy
Educational AI Tools
Coddy helps you write real code in your browser with an AI tutor (Bugsy) that guides you from your code and errors—without pasting answers.

What does Coddy do?
Coddy is an interactive coding platform designed for learning by doing. Open a lesson, type in the code editor, run it, and see results immediately—no installation or environment setup required.
Instead of handing you finished solutions, Coddy’s AI tutor (Bugsy) reads your actual code and your actual error message. It explains what went wrong and points you toward the fix directly in the context of your lesson, helping you get unstuck quickly.
The catalog includes interactive lessons across 20+ languages and technologies, such as Python, JavaScript, TypeScript, React, Next.js, Java, C/C++, C#, Go, Rust, SQL, HTML, CSS, PHP, Lua, Ruby, Swift, Docker, Git, Excel, and AI prompt engineering. You can also practice with browser-based playgrounds plus references, cheat sheets, and test cases.
Coddy supports streak-based practice with freeze days, weekly new challenges, and progress that syncs across web and mobile (iOS and Android), with offline lesson support. Certificates of completion are available for courses you finish.
Does Coddy let me write code myself, or does it generate full solutions?
You write and run real code in the browser. Bugsy supports you by explaining your specific errors and guiding you toward a fix without pasting a working answer.
Do I need to install an editor or set up a coding environment?
No—lessons run in your browser. You can open a lesson, use the code editor, and run code without configuring an environment.
How does the AI tutor (Bugsy) help when I get an error?
Bugsy reads your actual code and the error message you see. It explains what went wrong and points you toward the next steps to resolve it.
