Overview

Mempalace is an open-source AI memory system that is designed to provide a robust and efficient way to store and retrieve information. The system is built on top of a palace architecture, which consists of wings, rooms, closets, and drawers. The palace structure is designed to mimic the human brain's ability to organize and store information, with each wing representing a specific topic or project, and each room representing a sub-topic or sub-project. The closets and drawers within each room are used to store specific pieces of information, such as verbatim transcripts or compressed data using the AAAK compression dialect. The system also includes a knowledge graph, which is a temporal entity-relationship triple store that allows for efficient querying and retrieval of information. The Mempalace system is designed to be highly scalable and can handle large amounts of data, making it suitable for a wide range of applications, from personal note-taking to large-scale enterprise data management. The system is also highly customizable, with a range of tools and plugins available to extend its functionality. Overall, Mempalace is a powerful and flexible AI memory system that has the potential to revolutionize the way we store and retrieve information. Mempalace has achieved a 96.6% Recall@5 on LongMemEval, which is the highest zero-API score published. It has also achieved 100% recall with optional Haiku rerank. The system is local, free, and does not require an API key. Mempalace has a range of features, including palace audit and guided repair tooling, which allows users to improve the organization of their palace and repair any issues that may arise. The system also includes a range of commands, such as `mempalace audit` and `mempalace instructions audit`, which provide users with a structured approach to auditing and repairing their palace. Overall, Mempalace is a highly advanced and powerful AI memory system that has the potential to greatly improve the way we store and retrieve information.
