Refraction is an AI-driven developer productivity tool that automates repetitive engineering tasks including code generation, unit tests, documentation, refactors, style fixes, regexes, SQL, and CI/CD snippets. The site highlights adoption metrics (~13.7k developers, ~65.1k code generations, >2.9M lines of code generated). Core capabilities include generating or improving unit tests and inline documentation, performing code transformations (language translation, modernizing patterns, extracting literals), adding debug statements, explaining code and concepts, generating Mermaid diagrams, regexes, SQL, and CI/CD pipelines, and producing security/policy-like artifacts. Integrations include editor extensions (VS Code, JetBrains, Sublime), a terminal/CLI workflow, and GitHub PR autoreview. Pricing tiers listed are Hobby (Free), Pro ($8/month or $80/year), Team ($14/user/month or $140/user/year), and Enterprise (contact sales). The site mentions a trial in the header (“Free 7‑day trial”) while the FAQ references “free for 10 uses,” an inconsistency to note when signing up.
