About

Greptile is an AI tool that indexes your entire codebase to create a searchable, queryable knowledge base. Rather than reviewing individual PRs, Greptile answers natural language questions about your code: "How does authentication work?", "Where is payment processing implemented?", "What are all the database migrations?". This makes it invaluable for onboarding new developers, documenting legacy systems, and understanding large codebases. Greptile generates API documentation, provides PR context by connecting changes to the broader codebase, and enables multi-repository search. It is particularly useful for teams with large, poorly documented codebases where institutional knowledge has been lost. The auto-generated documentation helps fill the knowledge gap without requiring developers to write docs manually. Pricing has a free tier for personal use. The Pro plan starts at $20/month for teams. Greptile is complementary to traditional code review tools—it helps with understanding rather than reviewing. Pair it with CodeRabbit for reviews and Greptile for codebase intelligence to cover both needs. For teams inheriting legacy code or onboarding rapidly, Greptile's codebase Q&A capability can dramatically reduce the time to productivity.
