Frequently Asked Questions

What is AtAt and how does it work?

AtAt is a native macOS application designed to act as your personal agent within any app. By typing @@ in any text field, you can trigger your agent to assist with tasks, rewrite text, or provide answers without leaving your current workflow. It also features advanced screen capture, clipboard history, and text completion tools.

Which AI agents can I use with AtAt?

AtAt is flexible and allows you to "bring your own agent." It works out of the box with Claude Code, Codex, Grok, Cursor, Pi, Hermes, OpenCode, and Antigravity. You can also connect your own API keys from providers like OpenAI, Anthropic, or DeepSeek, or use local models via Ollama.

Is my data private when using AtAt?

Yes. By default, your history, clipboard data, and settings stay locally on your Mac. AtAt does not sit between you and your agent; prompts and context are sent directly from your Mac to your chosen provider. Optional iCloud Sync is available but remains under your control, using your private iCloud container.

Do I need an internet connection or an agent to use AtAt?

No. Even without an agent, AtAt functions as a powerful, native screenshot and productivity tool. You can use it for area/window/scrolling captures, screen recording, OCR, and managing your clipboard history (via ⌘⇧V) entirely offline.

What are the system requirements for AtAt?

AtAt requires an Apple silicon Mac running macOS 15 or later. Certain advanced features, such as Siri AI integration or specific UI surfaces, may require newer versions of macOS (e.g., macOS 26+).

How can I contact AtAt support or request a refund?
