Problem

Asking a model about a corpus without structure gives you fluency without a trail. The useful unit of memory is not the whole document dump — it is the graph of what the question actually depends on.

How it works

Hippograph is a portmanteau of hippocampus and graph, and a play on hippogriff. It uses knowledge graphs as structured memory over a corpus: deconstruct first, then ask with sources.

It is easier demo’d than said — there is a video on the site. The long writeup is the KG-RAG series on the technical blog.

Who it is for

Anyone who needs answers that can point back at a structured representation of a corpus, not just a nearest-neighbor chunk.
