Automated Reviews
Greptile automatically reviews pull requests and highlights potential bugs, logic errors, performance concerns, and maintainability risks while providing explanations for its findings.
Repository Search
Developers can ask questions about their repositories and receive context-aware answers that help them understand code relationships, locate relevant implementations, and investigate technical decisions.
