The Rill window on its start page. Under Good evening, one large field reads Search, enter an address, or send a task, with room around it. Below, Your tabs are sorted by AI into groups such as Art collection, Understanding music, CSS color schemes and Changepoint research. Beside them, Today in your projects lists finished tasks from Claude Code and Codex. On the wall, Monet’s Water Lily Pond hangs above Send a task or ask and the tabs, and the At work tray lists three tasks from Claude Code and Codex.

Your tabs in groups and your history in days, sorted by the agent you already use.

Your tabs on the start page, in four groups: Music videos, Land and climate, Art collection and Space imagery, each with a one-line summary. Today in your projects lists portfolio, newsroom-charts, lessons and lake-temps.

Your tabs, sorted

AI groups your open tabs on the start page. Your tab bar stays as you left it.

Questions

What does it cost?

Rill is free. AI features run on your Claude Code or Codex plan.

Do I need Claude Code or Codex?

For the AI features, yes. Browsing works without them.

Will an agent change my code without asking?

New tasks are read-only until you allow edits, and in git repositories each edit can be undone.

What about prompt injection?

Agents read pages as untrusted text, in their own tabs without your logins, and click or type only when you allow it. That lowers the risk; it doesn’t remove it.

How do I get updates?

Rill lets you know when a new version is out.

Which Macs does it run on?

Macs with Apple silicon, on macOS 14 or later.
