How to use this list

Each project is tagged across three dimensions:

| Column | Values | Meaning | |--------|--------|---------| | Open / Close | Open source · Managed · Closed | Whether you can self-host, and whether a hosted offering exists | | Category | Memory Tool · LLM Framework · Optimizer · Storage | Where it sits in the stack | | Storage | Graph · Vector · Graph, Vector | How it represents and retrieves memory |

• Memory Tool — purpose-built to give agents persistent, retrievable memory.
• LLM Framework — general agent/app frameworks that include a memory module.
• Optimizer — improves retrieval, prompts, or embeddings rather than storing memory directly.
• Storage — the underlying database (vector store or graph DB) a memory layer is built on.

Types of AI memory

Most memory systems combine a few well-established kinds of memory:

• Short-term (working) memory — transient context held within the model's context window for a single task or conversation.
• Long-term memory — information persisted externally and retrieved across sessions. It's commonly broken down into:
• Episodic — specific past events and interactions ("what happened").
• Semantic — facts, preferences, and entities ("what is true").
• Procedural — reusable workflows and skills ("how to do something").

Implementations differ mainly in how they store and retrieve this memory: vector search for semantic similarity, a graph for entities and relationships, or a hybrid of both (often with keyword/BM25 signals on top).
