Refraction
Refraction is an AI-powered code generation tool for developers that refactors code, generates documentation, creates unit tests, and more. The tool allows developers to simply copy and paste a block of code and select their language or framework to generate code, and the AI algorithm automatically generates the corresponding code using natural language processing and machine learning.

What is Refraction?
Refraction is an AI-powered code generation and refactoring tool designed for developers who need to improve code quality, generate tests, and produce documentation without spending hours on maintenance tasks.
It supports 29 programming languages and focuses specifically on the high-friction tasks that consume developer time but don't advance features: writing unit tests, adding docstrings, refactoring for readability, and converting code between languages.
The tool's test generation feature is particularly valued: paste any function and Refraction produces a comprehensive suite of unit tests covering happy paths, edge cases, and error conditions a task that most developers deprioritize due to time pressure but that directly reduces production bugs.
Language conversion mode handles the tedious process of porting code between languages (e.g., Python to TypeScript) with idiomatic output rather than a literal translation.
Refraction integrates into VS Code via an extension and also operates as a web app, making it accessible to teams regardless of their editor preference. The freemium model provides a meaningful number of free operations per month, while paid plans unlock unlimited usage and priority processing for teams with high-volume refactoring or documentation workloads.
