Refact AI

Refact.ai is an open-source AI coding assistant that supports self-hosted deployment with fine-tuning capabilities on private codebases, enabling organizations to train a custom AI coding model on their own code that understands internal conventions, patterns, and domain-specific knowledge that generic models trained on public code lack. Its VS Code and JetBrains plugins provide familiar IDE integration while the self-hosted backend keeps all code and model weights within the organization's infrastructure. Enterprise organizations with strict data governance requirements and teams wanting AI coding assistance personalized to their codebase use Refact.ai for its unique combination of AI capability and deployment privacy.
