Score: 6.0/10 (Innovation: 7, Technical: 6, Documentation: 5, Utility: 6)

AtAt is a macOS utility that lets you invoke an AI agent (like Claude Code or Codex) directly in any text field by typing '@@', integrating AI assistance into any app. It supports local models, API keys, and includes features like clipboard history and screen capture. While innovative in its system-wide integration and agent invocation, it is a commercial product with a limited open-source presence (only a Homebrew tap).

Target audience: Mac power users, developers, and knowledge workers
