AI layer
Data Layer
Knowledge bases, embeddings, and structured data
What lives here
The pipes that feed AI. This layer includes knowledge bases, embeddings, vector stores, and data pipelines. When an agent or LLM needs to retrieve information, it goes through this layer. Schema markup, structured data, and entity graphs live here.
Two dimensions
Every tool gets a category (what job it helps with, 16 options like Productivity or Automation) and a layer (where it sits in the AI stack, one of five). They are independent. E2B is Automation + Infrastructure. Braintrust is Productivity + Infrastructure.
