rekal vs MemoryPilot

rekal: rekal provides long-term memory for LLMs via an MCP server. It stores memories in a local SQLite file and retrieves them using hybrid search (BM25 keywords + vector semantics + recency decay). It works with any MCP-capable agent like Claude Code, Codex CLI, and OpenCode.; MemoryPilot: MemoryPilot is a state-of-the-art MCP memory server that gives AI coding assistants persistent, searchable memory. It features hybrid search (BM25 + multilingual embeddings), temporal knowledge graph, GraphRAG, AAAK compression, and zero-shot auto-classification. It is 100% local, runs as a single binary, and achieves 99.1% R@5 on the LongMemEval benchmark.
