Improve your AI infrastructure - AI memory engine

In AI Agent development, “memory capability” has always been a pain point—traditional RAG systems have low accuracy rates and isolated, unrelated data, while ChatGPT-like models are even more “forgetful,” unable to continuously reuse historical information.

The open-source tool Cognee that I’m recommending today can build an accurate and persistent AI memory layer with just 6 lines of code, and can even replace traditional RAG, giving AI Agents dual capabilities of “long-term memory + logical reasoning.” In testing, answer relevancy reaches an impressive 92.5%!

Cognee is an open-source AI memory tool and platform, with its core positioning being transforming raw data into “reusable, inferrable” AI Agent memory. What makes it particularly special is that it’s not limited to single vector search, but combines vector databases + knowledge graphs, allowing data to be searched by “semantics” and connected through “relationships,” fundamentally solving the shortcomings of traditional RAG.

Accuracy that Crushes Traditional Solutions Official data shows that Cognee’s answer relevancy reaches 92.5%, far exceeding traditional RAG’s 5% and pure ChatGPT’s performance;

ECL Pipeline that Replaces RAG Uses “Extract - Cognify - Load” to replace traditional RAG, supporting more complex logical reasoning;
