Rill Browser

Rill Browser

Rill brings Claude Code and Codex coding agents into the browser: press ⌘E to launch a task on any page, and the agent will match your project and report back on progress. It also supports AI tab grouping, web page Q&A, and multi-tab comparison. The software is free, AI features rely on your own coding agent subscription, and it currently supports only macOS 14 and above on Apple silicon.

About This Tool

What Is Rill Browser

Rill is a macOS browser (Beta) positioned as "a browser that lets Claude Code and Codex work alongside you." It puts coding agents directly into the browsing context: when something comes to mind on a web page, you don't have to switch to the terminal—just press ⌘E on the original page to assign the task to an agent.

Confirmed Main Features

  • Launch tasks within the page: Press ⌘E on any page to send a task or question, and the result comes back in place without opening a separate terminal window.
  • Automatic project matching: Rill identifies projects from your Claude Code and Codex history, and tasks automatically land in the corresponding project. The official site says no extra setup is needed.
  • Agents work in the background and report back: Agents process tasks in parallel while you read and proactively notify you when done, so you don't have to keep checking.
  • AI tab grouping: The browser groups tabs based on what you're doing, reducing manual organization.
  • Web page Q&A and tab comparison: Ask questions about the current page and have answers displayed beside it; you can also select up to six tabs to generate a comparison table citing content from each page.
  • Agents browse in separate tabs: Agents within a project read web pages in their own tabs, without using your login state, and you can take over when needed.
  • Voice input (Beta): Hold Fn to speak your idea and hand it to a coding agent for execution; must be enabled in settings.
  • Standard browser capabilities: Passwords are stored in Keychain, private windows are supported, and login information can be imported from Chrome, Arc, or Safari; it can also be used as a regular browser when AI features are disabled.

Requirements and Platform

AI features require you to already have Claude Code 2.1.261 or above, or Codex CLI 0.144.4 or above. Rill is currently available for download on Apple silicon Macs running macOS 14 or later and is in Beta.

Pricing

The official site currently states that Rill is free, and AI features run on your existing Claude Code or Codex plan, requiring no new subscription and no API key. The official site does not provide other pricing or paid version information.

Who It's For

If you regularly use both a browser and coding agents, and want to handle "researching, reading pages, and assigning tasks" in the same window, Rill's positioning fits exactly this kind of workflow. If you don't use Claude Code or Codex, you can still use it as a regular browser, but you won't get the agent-related capabilities.
