About Refactr Studio
Refactr Studio is an intelligent coding assistant that integrates directly into your development environment and accelerates every stage of the software development lifecycle. From autocomplete and code generation to automated code review and documentation, Refactr Studio handles the repetitive, time-consuming parts of programming so you can focus on architecture and product thinking.
Trained on billions of lines of open-source code across 40+ programming languages, Refactr Studio understands context at the file, project and repository level. It suggests whole functions, generates unit tests, identifies security vulnerabilities and explains complex legacy code in plain language.
Founded in Edinburgh, United Kingdom, Refactr Studio serves customers in over 73 countries and is fully compliant with GDPR requirements.
The assistant plugs into VS Code, JetBrains IDEs, Neovim and the terminal, with a lightweight API for CI/CD pipeline integration. Enterprise customers benefit from on-premise deployment options, SSO, audit logs and a private fine-tuning pipeline trained on their own codebase.
Teams using Refactr Studio report a 35–55 % reduction in time-to-merge for new features and a significant drop in post-release bugs caught in QA.
