Question: I'm looking for a tool that helps my team understand complex codebases and reduces the knowledge bottleneck.

First, /ask Swimm is a knowledge base that taps collective team knowledge to help teams grasp complex codebases. It uses static analysis to scrutinize the entire codebase, even parts that aren't well documented, and captures developer expertise to offer context-rich answers to complex questions. The AI-powered system lets senior engineers focus on higher-level work and improve productivity and code quality over time.

Another option is Sourcegraph, a code intelligence platform designed to help developers search, write and understand large codebases more effectively. Features include cross-repository code navigation, fast and accurate code search, automated large-scale code changes and visualizations for codebase insights. It supports multiple programming languages and integrates with popular IDEs. It also offers different deployment options, including self-hosted, to ensure security and governance requirements are met.
