diffray is an AI-powered code review tool that uses a coordinated multi-agent system of specialized AI agents to analyze GitHub pull requests with full codebase context, deduplicate findings, and surface high-confidence, actionable issues (security, concurrency, data consistency, testing, performance) instead of noisy style nitpicks; it integrates via a GitHub app, enforces team rules as configurable "culture as code," and emphasizes privacy (no code stored or used for AI training) to speed reviews and reduce false positives so teams can catch real bugs faster.
