What Sage AI does
Sage is a self-generating, self-maintaining knowledge base for your code with in-built chat, accelerating expertise, and comprehension of any codebase. Documentation is perpetually stale, codebases become increasingly old, large, and complex, and knowledge remains siloed within individuals and teams. As a result, engineers take 8-12 months to become fully operational, enterprise code becomes slow and unmaintainable, and core knowledge is continually lost upon engineer turnover. Sage is changing this reality. We take your code and automatically generate a symbol-level knowledge base that self-updates to remain forever fresh. We integrate with source control to pull your code and generate a symbolic graph representation of functions, classes, interfaces, types, etc., automatically determining the relevant context for each symbol, and using LLMs to annotate and propagate documentation via traversals of the symbol graph. Sage revolutionizes the way teams and individuals interact with and understand their code, ensuring that knowledge is always accessible, up-to-date, and interactive.

Sage AI
Self-maintaining code knowledge base
We build Sage, a knowledge base that automatically generates and maintains itself from your code. It integrates with your source control to pull your entire codebase, builds a symbol-level graph of code elements like functions, classes, and types, and uses large language models to annotate and update documentation continuously. This keeps your code knowledge fresh and easily searchable via an interactive chat interface, so engineers spend less time ramping up and navigating complex code.
We live in San Francisco and remote locations. After YC, we plan to base the company in San Francisco to stay close to our users and the tech ecosystem.
San Francisco is where we live and where many of our early users are located. Being here allows us to build relationships with engineering teams directly and recruit talent if needed.

Frequently Asked Questions
Is this the real Sage AI YC application?
No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Sage AI's public data (launch notes, founder backgrounds, product description). It shows how a company like Sage AI would present itself to YC, not the text they submitted.
What YC batch was Sage AI in?
Sage AI was part of the Y Combinator Winter 2023 batch.
Who founded Sage AI?
Sage AI was founded by Joshua Ying.
What does Sage AI do?
Your self-generating, self-maintaining code knowledge base.
