How to use it

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.

When to use Code Writer

You need a Python script to rename 400 files based on a CSV, or a TypeScript utility to debounce a search input, and writing it from scratch would cost you an hour you don't have. Describe what you want in plain English — the inputs, the outputs, any edge cases you care about — pick a language, and get working, commented code back in one pass. The inline comments explain the logic as it goes, so you can review it confidently even if the language isn't your strongest. The model runs locally in your browser tab, so internal tooling ideas, unreleased product code, and anything sensitive in your prompt stay off external servers. Copy the output into your editor, run the linter, and test it — it's a strong starting point, not a pull request.

  • Generate a Python script to batch-rename files from a CSV mapping
  • Write a TypeScript hook that debounces an API search input
  • Scaffold a Go HTTP handler with error handling and logging

About this tool

Describe what you need in plain English, pick a language — Python, JavaScript, TypeScript, HTML/CSS, Rust, or Go — and get working, commented code back in seconds. Good for scaffolding boilerplate you've written a hundred times, prototyping a quick script, or bridging a language you don't know well. The output includes inline comments explaining what each section does. Processing stays on your machine — no prompts or generated code ever touch a server — so internal tooling ideas stay internal.

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

Is this AI code writer private? Does it send my prompts to a server?
No. A local model generates code directly in your browser tab — your prompts, descriptions, and output stay on your machine. Nothing is forwarded to OpenAI, Anthropic, or any other service.
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. Review it, run your linter, and write tests before shipping — the model handles structure and logic well but can miss project-specific conventions.
