ZenNotes is a free, open-source, local-first Markdown note-taking application for Windows, macOS, and Linux, with a self-hosted web edition. It stores notes as ordinary Markdown files without requiring a proprietary database. Its keyboard-focused editor supports Vim motions, command shortcuts, and customizable navigation. Users can work in editing, preview, or split-screen modes with multiple tabs and reference panes. Markdown rendering includes mathematical notation, Mermaid diagrams, wiki links, and embedded media. Built-in organization tools provide tasks, tags, daily notes, archives, and full-text searching. A first-party MCP server allows compatible AI assistants to interact with the same note collection. Command-line tools, floating windows, and macOS Raycast integration extend note management beyond the main interface.
