Code Writer is a free, browser-based AI tool that generates code in Python, JavaScript, TypeScript, HTML/CSS, Rust, and Go. It runs on your computer — no code or prompts are sent to any server. Describe what you need in plain English, pick a language, and get working, commented code instantly.
How to Use
1
Choose a language
Select from Python, JavaScript, TypeScript, HTML/CSS, Rust, or Go using the language pills.
2
Describe what you need
Write a plain-English description of the function, script, or component you want to build.
3
Generate the code
Click generate and the AI will produce commented, readable code matching your description.
4
Copy and iterate
Copy the code to your editor, test it, and regenerate with a more specific prompt if you need adjustments.
Tips
Be specific about inputs, outputs, and edge cases — 'a function that sorts a list of objects by date descending' beats 'sort stuff.'
Ask for small, focused functions rather than entire applications for the best results.
Use the generated comments to understand the logic and catch any issues before running the code.
Pair this tool with your IDE's linter to quickly spot syntax or type errors in the output.
Frequently Asked Questions
Is this AI code writer private? Does it send my prompts to a server?
No. The AI model runs on your computer — your prompts and generated code stay on your computer, and nothing is sent to OpenAI, Anthropic, or any other server.
Which programming languages are supported?
Python, JavaScript, TypeScript, HTML/CSS, Rust, and Go. Just select a language pill and describe what you want.
Does the generated code include comments?
Yes. The AI is prompted to include inline comments explaining the logic so the code is easy to understand and modify.
Can I use this for production code?
The generated code is a solid starting point, but always review and test it before using in production. The AI runs locally on your device.
