Sage AI is a tool that automatically generates and maintains a code knowledge base. It can help engineers quickly generate documentation, reducing friction in code understanding and collaboration. Sage AI performs deep contextual interaction with source code by building and traversing the code's symbol graph to enrich knowledge. It can automatically adjust to stay up-to-date and supports integration with version control systems. Sage AI accelerates and maintains expertise in code repositories, addressing issues such as outdated documentation, complex code, information fragmentation, poor collaboration, and new employee onboarding.
