Refact is an autonomous AI software engineering system and code assistant. It functions as an agent orchestrator capable of planning, executing, and managing multi-step development workflows to complete complex software tasks independently.
The system distinguishes itself through agentic state management, using isolated worktrees and versioned checkpoints to allow autonomous agents to experiment with code changes and roll back to stable states if tasks fail. It further extends its capabilities via the Model Context Protocol, connecting the AI engine to external databases, version control systems, and automated web browser control for research and validation.
The platform provides a comprehensive suite of AI assistance tools, including in-line code completion with structural analysis, a conversational chat interface, and a retrieval-augmented generation engine for semantic code search. These are supported by a local indexing system that uses vector databases for codebase context and a command line interface for system-level automation and process control.
