Refraction
What it is
Refraction is an AI code assistant built by the software studio Twistag and powered by OpenAI models. Developers paste or select code and choose a task: detecting bugs and suggesting fixes, refactoring to modern practices, adding inline documentation or types, writing unit tests for a chosen framework, inserting debug statements or pulling hardcoded values into variables. It can also generate functions, SQL queries, regular expressions, Mermaid diagrams, CI/CD pipelines and Content Security Policies from plain-language descriptions, and convert code or CSS between languages and frameworks. The company says it supports 56 languages. Extensions are available for VS Code, JetBrains IDEs, Visual Studio, Sublime Text, GitHub and the terminal.

More context from AI BirdView
Rather than one open-ended chat box, Refraction organizes AI help into a menu of specific developer chores. That task-first design makes it quick to pick the job you need, from writing tests to generating a regex, without crafting a detailed prompt each time.
- Unit test generation targets the testing framework you choose.
- Documentation, type annotations and debug statements can be added to existing code in one step.
- Conversion tools translate code between languages and CSS between frameworks.
- Plain-language generators cover SQL queries, regexes, Mermaid diagrams, CI/CD pipelines and Content Security Policies.
- Extensions bring the tools into VS Code, JetBrains IDEs, Visual Studio, Sublime Text, GitHub and the terminal.
Refraction is best for individual developers and small teams who want an inexpensive helper for routine tasks like tests, docs and refactors. A practical tip: use the free uses on the chores you find most tedious, such as test writing, to judge output quality, and remember to review generated tests carefully before relying on them in your pipeline.
