AgentBell is a native macOS menu bar app for devs who use multiple AIs and IDEs. It unifies cognitive continuity—task state, focus, and light emotional presence—via hooks and MCP across tools like Cursor, VS Code, Claude, and Codex. Built on workflow signals, not on reading your code or chats. Get quick awareness from the menu bar, macOS notifications, sound, and an optional Live2D companion, so your context is less likely to vanish as you switch tools and sessions.
