Your code has a style.
Your AI should learn it.

Neon AI is building a style profile of how a developer writes code, from naming and structure to comments and idioms, to guide code generation toward those conventions. It’s in development.

Your habits, one change at a time.

Neon AI reads a sample of your Python, lists the habits it finds and uses them two ways: as instructions for Copilot, and as rewrites you review in the file. The VS Code extension is in private beta.

Start with the code you already write.

Four kinds of pattern make the profile: architectural, behavioral, cognitive and visual. Personalized code generation is designed to use that profile.

invoices.py
▾ tests/billing/

Architectural

How projects are structured and composed.

How problems are reasoned through in code.
