Hollow Pro

Your agent is waiting.
Your notch tells you.

Claude Code asks for a permission, Codex finished its turn: the project shows up in the notch and the neon lights up. One click takes you back to where the agent runs: Terminal, VS Code, Claude or ChatGPT.

Closed, it shows what matters.

The notch stays black. When something happens, it says so on each side of the camera.

This is Hollow’s layout editor, as in its settings. Drag a module into the notch, from one half to the other, or back to the modules. Two modules share the notch: the left one stays, the right one makes way for alerts.

Questions

Which AI agents does Hollow show?

Claude Code, in the terminal, your editor or the Claude app, and Codex, in the ChatGPT app or the terminal. Hollow adds its hooks to Claude Code by itself. Agents are part of Hollow Pro.

Does Hollow read my code?

No. Claude Code and Codex only tell Hollow when an agent starts, waits or finishes, with its project and the conversation title. None of it leaves your Mac.

Does Hollow work on a Mac without a notch?

Yes. On a display without a notch, Hollow draws one. You choose where it shows: the built-in display, the main display or all displays.

Does Hollow read my messages?

No. Hollow only reads the badge on the Dock icon of Slack and WhatsApp: the number of unread messages, never their content.

Which permissions does it ask for?

Accessibility, to show the volume and brightness keys in the notch and read the Dock badges; Bluetooth, for the battery of your devices; Calendar, for your meetings.

Is it a subscription?

No. You pay once, and updates are free until version 2.0.

What does the trial include?

Which languages?

English, French, Spanish, German and Simplified Chinese. Hollow follows the language of macOS, or the one you pick in its settings.

What do I need?

A Mac with macOS 14 Sonoma or later.

How do I report a bug?
