Refraction

AI-Powered Code Generation for Developers

Refraction is an AI-driven code generation tool designed to automate the tedious aspects of software development. It enables developers to generate unit tests, documentation, refactor code, detect bugs, and perform dozens of other code-related tasks across 56 programming languages — from Python and JavaScript to Rust, Solidity, and beyond.

Core Capabilities & Features

Refraction offers a comprehensive suite of features that streamline development workflows:

• Code Quality & Optimization: Detect bugs, refactor code with modern practices, style check, add types, and separate hardcoded literals • Testing & Documentation: Generate unit tests for any framework, create inline documentation, and explain code purpose • Code Generation: Write new functions, generate SQL queries, create regex patterns, and build CI/CD pipelines from natural language descriptions • Cross-Language Support: Convert code between languages and CSS frameworks • DevOps Tools: Generate Content Security Policies, create diagrams with Mermaid, and build deployment pipelines • Learning Aid: Get detailed explanations of programming concepts and understand unfamiliar code

Seamless Developer Workflow Integration

Refraction integrates directly into your existing development environment through extensions for VS Code, JetBrains IDEs, Sublime Text, Visual Studio, and GitHub. A terminal interface and autoreview capabilities further enhance accessibility. Simply paste a code block, select your language or framework, and let the AI generate what you need.

Proven at Scale

Trusted by over 13,700 developers worldwide, Refraction has generated more than 2.9 million lines of code across 65,000+ code generations. The platform supports an extensive range of languages including mainstream options (JavaScript, Python, Java, C#, Go, Rust), functional languages (Haskell, Elixir, OCaml), and specialized tools (Solidity, GraphQL, ABAP).

Who It's For

Refraction is built for developers who want to focus on solving problems rather than writing boilerplate. Whether you're documenting legacy code, writing tests for existing functions, learning a new language, or simply need to generate routine code faster, Refraction helps you build great software with less manual effort.
