About Refraction
Refraction is an AI-powered coding assistant built by Twistag that automates repetitive development tasks such as writing unit tests, generating documentation, refactoring code, and detecting bugs. Rather than replacing developers, it slots into existing workflows: teams can call it from a web app, a terminal or CLI, or plugins for VS Code, Sublime Text, JetBrains IDEs, and Visual Studio, plus a GitHub AutoReview integration for pull requests. It supports 56 programming languages, from mainstream choices like Python, JavaScript, and Java to more niche ones like ABAP and Assembly, and can translate code between them. Beyond code generation, Refraction handles adjacent tasks developers often outsource to search engines or Stack Overflow: writing regex patterns and SQL queries, generating CI/CD pipeline configs, converting CSS styles, producing Content Security Policy headers, and adding type annotations. It runs on OpenAI's models under the hood. The tool is aimed at individual developers and engineering teams who want to offload boilerplate work rather than write it by hand. Its own site reports over 13,700 developers and 65,100 code generations to date. One limitation: pricing details are not published on the homepage, so it is unclear what a team should budget before trying it.
