akb vs zettelforge

akb: AKB is an agent knowledgebase that serves organizational memory for AI agents over the Model Context Protocol (MCP). It provides hybrid semantic + keyword search, structured tables, files, and a URI graph, all backed by Git for version history. Designed as a drop-in alternative to Confluence or Notion for MCP-aware agents like Claude Code, Cursor, and Windsurf.; zettelforge: ZettelForge provides persistent memory for AI agents with automatic entity extraction, knowledge graph construction, and STIX ontology. It supports offline operation with no API keys or cloud dependencies. It features alias resolution, blended retrieval, and memory evolution for cyber threat intelligence.
