#### Human-like Code Understanding `@codebase`

PureCode AI builds a comprehensive mental model of your entire codebase, understanding relationships between components and business logic just like a senior developer would.

You can create advanced summary indexes from **⚙️** **Advanced > Codebase indexing.**

It enables the model to

* Creates a summary of the whole codebase for broad understanding of codebase features, approaches, and key checkpoints.
* Creates a summarized understanding of each file to improve natural language understanding and retrieve the relevant summary and part of code efficiently.
* Then, when you make a query, it takes the most relevant piece of code along with file summaries and the whole codebase.
