This page matches words and runs in your browser, and nothing you type leaves it. The real vault keeps plain markdown files on your machine and also finds entries by meaning.
Keep it between sessions.
Your agent saves with save_context and recalls with get_context, in Claude Code, Cursor, Codex or Windsurf.
