rekal vs arkon

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.; arkon: Arkon is a self-hosted, enterprise-grade knowledge management layer that bridges organizational data and AI clients as a centralized MCP Server. It compiles SOPs, policies, and internal docs into a structured, traceable knowledge wiki, serving it to Claude and other LLMs through a permission-scoped endpoint. It provides fine-grained RBAC, workspace isolation, and a wiki browser with knowledge graph.
