Rill is an AI-native browser built around the Claude Code and Codex you already use. Browse normally, then press ⌘E on any page to turn what you're looking at into a task for your agent. Rill finds the right project, passes along the context, and the agent works while you keep browsing. It also sorts your tabs into themes, turns your history into days you can search, and brings every project your agents are working on into one place. Free, on the plan you already have.
Hi Product Hunt, I'm William! I made Rill because I want to always stay in the flow.
As an ADHD, I never liked code-switching. My best ideas for work come when I'm supposedly not working at all: watching something for fun, reading things and following a rabbit hole, looking at how someone else solved a problem. Then when an idea hit me, I'd have to stop, switch to coding agents, find the project and explain it all, and most of the time I just didn't.
Rill is my way of removing that code-switching. It's a browser with your Claude Code or Codex working alongside you. When something on a page gives you an idea, you say so right there, and an agent starts on it in the right project. You don't have to spend time looking for the right folder, rephrasing everything you just saw on the web, and you don't switch in and out of work mode. The work goes on with you in the flow.
This matters now more than ever. Agents have shortened the distance between ideas to output near zero. So the bottleneck is capturing the idea at the moment you have it. That moment is nearly always while you're taking something in, and that is what a browser is for.
Rill is a free AI-native browser. It's WebKit-based, which means it's native to Mac. And it runs on the Claude Code or Codex plan you already have, so you don't have to buy a new subscription for all of its agentic capabilities.c
How do you keep an idea today when it shows up at the wrong time?
@williamgaoharvard just installed it opened Projects, and every repo I've touched with Claude Code was already there, very quick setup.
@priya_kushwaha1 That's the goal! We want smooth setup for everyone. I personally really like the Stay Signed-In feature, which makes most sites I already signed in on Chrome to be signed in in Rill
@williamgaoharvard found a layout i liked on someone protfolio pointed at it and said make my homepage do this is anyone else using it mostly for design?
@shivam_kushwaha16 That's a great use case. Exactly the idea - no need to copy paste or re-explain context. Rill just brings it in to your coding agents
What a challenge it is to launch a browser nowadays! Why did you take that bet instead of building a Chrome extension? How are people reacting to the change?
All the best for the launch!
@patatruffe Thank you Romain! It definitely takes some courage to do a browser. We choose this form factor because we see agents as first-citizens. Chrome Extensions can only touch what's on browser and improve it, but we want to bring the agent capabilities into where people browse and have ideas.
We're very thankful to the whole WebKit infrastructure. Without it, Rill won't be possible. We've done some technical deep dive into Chromium and I can tell you it's crazy down there.
@williamgaoharvard Thanks for taking the time; looking forward to testing it!
No Chrome extensions is a real cost for me, mostly the password manager. Just curious are people using this as the daily driver or as a second browser?
@polman_trudoWhat password manager do you use? Right now we use Mac's keychain to save the passwords, and have enabled importing Chrome and other browsers' password into it. Happy to support 3rd party password manager as well.
Chrome extensions are definitely great. One feature we'll launch in the future is "Make your own extension". The top left beautiful painting island is actually reserved for that. This way you're able to create your own extension with one simple ask, and customize them however you want.

How is this different from Atlas, Comet or Dia? They all put AI next to the page.
@justin2025 Great question Justin! We're fundamentally different from all of them because we treat AI agents as first citizens.
Those "AI browsers" have a lot of cute functions that uses AI to improve your browsing, but they don't help with the actual heavy lifting that coding agents are doing today - run 1 week straight to solve a research problem, run 4 hours to create a great motion graphics video, go through 2000 old excel sheets with manual errors and sort all of them together. These are all things you can do with Astra and Fable today, and these are also things you can ask Rill to work on.
We have deep respect for that incredible capability coding agents bring, so we see browsing not as something to be dramatically improved with AI gimmicks, but as the starting point of innovative ideas that can lead to real building.
@meet_patel24 You get to see the project it picks when you send it - everything is visible so it's one click away to correct it
In case it still ends up in the wrong folder, Rill comes with its own Undo and Review, based on per-turn snapshot that's independent of the git you already have. So one more way to revert things
Read a migration guide for a library we're two major versions behind on, and told it to do the migration in our repo from that page. It took the guide as the brief. That used to be a ticket nobody picked up.
@jitendra_bhatt Glad it helped! Cool use case. That's exactly the idea behind Rill - when context is right there, we shouldn't need to code-switch and tell it to agents all over again. One simple ask should do
What would it take to send a task from my phone and have it run on my Mac at home? That would be the dream.
@deepaksingh09 We're thinking about it! Stay tuned for the mobile version!
