Your code appears here. Nothing is sent until you press Generate. Meanwhile, the cheat sheets answer most syntax questions instantly.

Prompts that work well

How to get code you can actually use

AI is good at the boilerplate you’d otherwise search for: parsing, reshaping data, regular expressions, SQL with a known schema, shell one-liners and config files. It is weaker at code that depends on your private codebase or on library versions it hasn’t seen.

  1. State inputs and outputs. “Takes a list of dicts with name and score, returns the top 3 names” beats “sort scores”.
  2. Give the schema. For SQL, list tables and columns, and say which database (PostgreSQL, MySQL, SQLite).
  3. Run it. Python, JavaScript and SQL results open straight in the Python compiler, JS playground or SQL editor. If it fails, press “Fix the error” there.

Need a regular expression? The regex tester has its own “describe it” AI mode that fills in the pattern and tests it live.

Frequently asked questions

Which AI model writes the code?

Requests go through Vercel AI Gateway to a current OpenAI GPT model tuned for fast, low-cost answers. The model is instructed to stay on programming topics and to return one clean code block with brief notes.

Is the generated code safe to use as-is?

Treat it like code from a colleague you haven’t worked with before: read it, run it, and test edge cases. For Python, JavaScript and SQL you can press “Run it” to execute the result immediately in the browser playgrounds.

Is it free? Do I need an account?

It’s free and needs no account. To keep it that way there is a fair-use limit of a few requests per minute per visitor.

What happens to my prompt?

Your request is sent to the AI model only when you press Generate, and is not stored on our side. Your last 12 generations are kept in this browser (localStorage) so you can go back to them; clear them any time.

How do I get better results?

Name the inputs and outputs, the language version or database, and constraints such as “no external libraries”. Paste a sample of your data if the shape matters.
