Cognee uses LanceDB for per-workspace isolated vector storage in its AI agent memory platform

The problem

Agent teams struggle with stateless context and homegrown RAG stacks that require juggling separate graph stores, vector stores, and ad hoc rules, raising reliability risks and slowing iteration. Cognee specifically needed a vector store that matched its isolation model, supported per-workspace development, and avoided the complex orchestration that traditional vector databases require.

Workflow diagram · grounded in source
1
Add data sources
trigger
“It ingests sources such as files, APIs, and databases”
2
Extract raw data
integration
“Extract: Pull data from various sources (files, APIs, databases)”
3
Cognify to knowledge graph
ai_action
“chunks and embeds content, enriches entities and relations, and builds a queryable knowledge graph”
4
Load to vector and graph stores
integration
“serve both graph and vector search from Kuzu and LanceDB”
5
Multi-step query retrieval
ai_action
“Applications built on Cognee query both the graph and the vectors to answer multi-step questions with clearer provenance.”
6
Memify knowledge refresh
feedback_loop
“Cognee's Memify pipeline keeps memory fresh after deployment by cleaning stale nodes, strengthening associations, and reweighting important facts, which improves retrieval quality without full rebuilds.”
Reported outcome

Adopting LanceDB accelerated Cognee's development cycle and improved reliability, enabling faster CI, cleaner multi-tenant setups, and more predictable performance, while also improving retrieval accuracy on multi-hop reasoning tasks.
