Read a document once.
Serve it forever.

Engram CaaS is Cache Augmented Generation as a Service: a hosted AI answer service for your document library at a fraction of the cost of traditional RAG systems. Connect your documents and we read each one once into the model's memory. Every question after that is answered straight from memory, with the same accuracy as retrieval based AI, with blazing fast speed.

Read once, then answer from memory

Read

We read each document once and hold it in the model's memory. When a document changes, the new version is read the same way.

Answer

Every question is answered straight from memory with blazing fast speed, and we never bill for input or context tokens.

Connect

Every library comes with an MCP endpoint, so your own agents, assistants, and tools can query your documents like any other tool.

A fraction of the cost

Your documents get read once at onboarding, then every answer comes from memory. Input and context tokens are never billed, so the same library of questions costs a fraction of what a per-token AI API charges you today.

The same accuracy

Answers are grounded in your source documents. Measured head to head against retrieval based AI on the same questions and the same material, the accuracy holds, confirmed by an independent judge. Quality you can put in front of your team and your customers.

Answers start in milliseconds

Your library stays warm in memory, so answers start in milliseconds whether it holds a handful of documents or your whole knowledge base. Speed stays steady as the library grows.
