Hatchdoor vs ZotSeek

Hatchdoor: Hatchdoor is an agent-native, self-hosted web app for managing Obsidian-style Markdown vaults, offering a fast web UI for browsing, searching, and editing notes. It provides AI agents with first-class access to the vault via the Model Context Protocol (MCP) for reading, searching, creating, and editing notes safely. Your Markdown files remain the source of truth, with Hatchdoor building a disposable SQLite read model for performance and features like keyword and semantic search.; ZotSeek: ZotSeek is an AI-powered Zotero plugin enabling 100% local semantic search to find academic papers by meaning, not just keywords. It integrates a built-in MCP server, allowing AI agents to semantically query the user's library and cite papers with deep links.
