Cognee.

TL;DR — Cognee is an agent memory layer that organizes information as connected entities and relations instead of flat text chunks.

What it is

It builds graph-based memory structures to improve long-horizon retrieval and reasoning.

Why it exists

Agents lose coherence when context is only appended text. Graph memory helps preserve structure and relationships.

Install

pip install cognee

Basic usage

# ingest documents and events
# build graph memory
# query relevant nodes for the agent

When to use, when to skip

Use it when this category is a bottleneck in your agent stack and you want faster delivery with fewer custom components.

Skip it when your workload is tiny, requirements are fixed, or a plain provider SDK plus a few local functions is enough.
