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

It starts on any page

An idea used to mean switching apps. Now you say it where you found it.

And it knows where the work goes

Your browser knows your projects. Each request lands in the right one.

And when it isn’t code

Need a flight? Ask the same way. Your agent goes looking, in a tab behind yours.

A note open over an arXiv paper. It holds This page and the words Try this method on my data., with the project longitudinal-study chosen and a Send button.
Press it, or keep scrolling.
A note open over the release post for Polars 2.0. It says Try this on one lesson., and the project lessons has been chosen for it.
A release note worth testing. It went to lessons.
A note open over a table of consumer prices. It carries the page and one row of the table that was pointed at, says Chart this against last year., and the project newsroom-charts has been chosen for it.
A row of a table, pointed at with a click. It went to newsroom-charts.
A note open over a type foundry's page. It carries the page and a paragraph that was pointed at, says Make my project pages like this., and the project portfolio has been chosen for it.
A page whose look you like. It went to portfolio.
A note open over Wikipedia’s article about New York City. It says Find a nonstop from SF to NYC, Nov 12 to 16., and its destination reads On the web.
A city worth the trip. It went to the web.

It finds your projects in your Claude Code and Codex history. There is nothing to set up.

No need to wait

Five agents are at work. You’re reading about a prairie.

They are in the corner of this page too. Keep scrolling.

A demonstration with sample projects.

While you read on

You never go and check. They ask, and tell you when they are done.

Say “book it,” and it does, up to the payment.

The corner of the Rill window, closer, with the essay behind. Under the tab being read is the tab of the task on the web, San Francisco to New York, a thin red-orange line at its edge. A bubble has come out of it over the essay: Claude Code, Nonstop from SF to NYC. Needs your answer. Morning or afternoon departure? Under it a box for an answer, the buttons Morning and Afternoon, and Reply.

Answer it, or keep scrolling. Answered. It carries on in the same tab.

While they work

Open as many tabs as you like. They are already grouped by what you were doing.

Your tab bar stays as you left it.

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.

While you browsed this page, the chart got made.

A chart titled July surface water temperature: one step, not a slope. Three lakes, Saimaa, Päijänne and Inari, each step up by one to two degrees at a changepoint between 1996 and 1997.
longitudinal-study “Try this method on my data.” Done · 2 files changed

A demonstration with a sample project. In Rill it is your own Claude Code or Codex, in your own projects.

At the end of the day

Your history reads like a journal: where you went, what you asked for, what got done.

Half remember a page? Describe it, and it is found.

History for Sunday, September 27: 64 pages in six stretches, summed up in a sentence, with a ribbon of the day. The stretches: Morning news and weather; Changepoint methods paper, with a task sent to lake-temps, done; Lunch reading; CPI chart for the newsroom, with a task sent to newsroom-charts, done.

After a few weeks

Every project your agents have touched, on one map.

Finished work is marked Done, wherever it happened.

Projects: 38 projects in 6 areas named by AI: Research and data, Writing and publishing, Design, Teaching, Home and life, and Tools and code. Four are lit as Done: lake-temps, newsroom-charts, portfolio and lessons.

Beta

Thought of something? Hold Fn and say it. Your coding agent gets to work.

Talking is in beta. Set it up once in Settings › Talking.

A note open over an article about dark mode. It holds the words Add a dark mode to the customer portal that follows the system setting., with the project customer-portal chosen and a Send button.

Get started

Three steps.

  1. Download Rill

    Drag it to Applications.

  2. Sign in to Claude Code or Codex

    Rill walks you through it. Use either, or both.

  3. Press ⌘E on any page

    Rill finds your projects for you.

Rill works as a browser without an agent, too.

  • Ask about a page

    The answer opens beside the page, from the agent you already use.

  • Compare tabs

    Pick up to six. Get a table that quotes each page.

  • Agents in a project read the web

    In tabs of their own, without your logins. Take one over when you want.

  • And the basics

    Passwords in your Keychain, private windows, your sign-ins brought over from Chrome, Arc or Safari.

Privacy

Your history and passwords live on your Mac.

  • Your agents, your sign-in

    AI features run the Claude Code or Codex on your Mac, under your own account.

  • History on your Mac

    Kept as files on your Mac, for as long as you choose.

  • Passwords in the Keychain

    Saved in your Mac’s Keychain, unlocked with Touch ID.

  • You choose what runs

    Tab sorting and day summaries can be turned off in Settings.

What each feature sends, in detail

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.

Can an agent buy something by itself?

A task on the web is told to stop before the step that pays, places an order, sends, posts or deletes, unless you plainly told it to go through with it. It cannot type into password, card or one-time-code fields.

What about prompt injection?

Agents read pages as untrusted text. In a project, an agent browses in tabs of its own, without your logins, and clicks or types only when you allow it. A task on the web works with your sign-ins, within the limits above. 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.

Your browsing. Your agents. One window.

Turns out the best interface for agents is just the browser.
