akb vs hippocampus

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.; hippocampus: Hippocampus is an open-source, self-hosted MCP memory server that provides persistent, cross-platform memory for AI assistants. Deploy once and connect to multiple AI platforms such as Claude, ChatGPT, Gemini, Cursor, and Perplexity, enabling them to share and recall context seamlessly. It uses a knowledge graph with local embeddings and encrypts the database at rest.
