omanote

omanote is a fast, open-source markdown editor for the terminal. Think nano for markdown: no modes, nothing to configure, one binary. Markdown renders as you type, and the raw syntax only shows on the line you are editing. Link notes with @, fuzzy-find or search inside every note with Ctrl+P, and open Claude Code, Codex, or Gemini beside your notes with Ctrl+G. Made for Omarchy, with a plugin in its marketplace. Runs in any terminal on Linux or macOS.
