Sage AI is a self-generating, self-maintaining knowledge base designed for code, featuring an integrated chat function to enhance expertise and comprehension of any codebase. It addresses the challenge of perpetually outdated documentation, increasingly complex codebases, and siloed knowledge within teams. Engineers often require 8-12 months to become fully operational, and enterprise code can become slow and unmaintainable, with core knowledge frequently lost due to engineer turnover. Sage AI transforms this scenario by automatically generating a symbol-level knowledge base from your code that continuously updates to stay current. It integrates with source control to extract code and create a symbolic graph representation of functions, classes, interfaces, and types, automatically determining the relevant context for each symbol. Using LLMs, Sage AI annotates and propagates documentation through traversals of the symbol graph. This innovation revolutionizes how teams and individuals interact with and understand their code, ensuring that knowledge remains accessible, up-to-date, and interactive.
