Refraction

Refraction is an AI-powered code assistant designed to help developers refactor code, generate documentation, and create unit tests across multiple languages and frameworks. Users paste a block of code into the web interface, select the relevant language or framework, and generate structured outputs such as cleaner implementations, test suites, or explanatory comments. The tool focuses on practical development workflows, including improving legacy code, enforcing consistent coding styles, and quickly producing boilerplate that typically consumes engineering time.

Refraction also supports tasks like adding or updating inline documentation, generating docstrings, and producing high-level summaries that aid onboarding and code reviews. It is particularly useful for individual developers, small teams, and startups that want to accelerate development without building extensive internal tooling.
