rekal vs memem

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.; memem: memem is a Claude Code plugin that gives persistent memory across sessions. It automatically extracts durable lessons from completed sessions, stores them as markdown in an Obsidian vault, and surfaces relevant ones as an Active Memory Slice. It is local-first with no cloud services.
