Big Idea
The argument in one line.
Claude Duet's new link to Claude Code on your own computer turns a cloud agent into a phone-sized remote control for your real, powerful machine and its existing sessions.
Who This Is For
Read if. Skip if.
READ IF YOU ARE…
You run Claude Code on a Mac or other always-on computer and want to keep working from your phone when you're away from your desk.
You're weighing personal agent platforms like Dots, Muse or Grokbot and want to know what Anthropic's Duet actually adds.
You edit video or ship small apps with Claude Code and want a way to push changes to production without opening a laptop.
SKIP IF…
You don't use Claude Code or don't have a computer you can leave powered on all day.
You want a hands-on setup tutorial; this is a demo and a pitch for why the feature matters, not a step-by-step guide.
TL;DR
The full version, fast.
Claude Duet is Anthropic's new personal agent app with its own cloud computer, and its latest update lets it message existing Claude Code sessions on your Mac and start new ones. Riley Brown shows five payoffs: reaching your real computer from your phone, editing a video by chatting with the session that made it, shipping an app change to production, triggering computer use remotely, and talking to sessions by voice. The catch is that your computer must stay on, so he suggests the free Amphetamine app. Starting a brand new session still has to be done manually.

Duet, powered by Opus 5.5, can now connect to Claude Code on your computer and spin up new sessions. It pairs a virtual cloud computer with a physical one.
01:35 – 02:48
02 · Listing sessions from the phone
From a phone Riley asks which Claude Code sessions ran on his MacBook Pro and Mac Mini in the past day and gets a list of ten.
02:48 – 06:55
03 · Reason 2: edit video from your phone
He asks Duet to rework a vertical video, moving a blender shot to the opening and speeding it to 1.1x, and a session on his Mac delivers a new version.
06:55 – 08:35
04 · Reason 3: build apps from your phone
A voice request to add an alternate style to the Agent Native site goes to its session, which ships a light mode to production.
08:35 – 10:35
05 · Reason 4: computer use and keep-awake tip
He triggers computer use to screenshot Descript, admits it trails Codex, and recommends the free Amphetamine app to keep the Mac awake.
10:35 – 11:40
06 · Reason 5: real-time voice
Using voice mode he asks a session to make a new video version with light background music and approves the request.
11:40 – 12:31
07 · Wrap-up and v2.video plug
He promises a deeper follow-up and pitches v2.video, a free GitHub-for-video-editing project he plans to open source in two weeks.
Atomic Insights
Lines worth screenshotting.
A personal cloud agent has a virtual computer; connecting it to Claude Code gives it a second, physical one with far more power.
Duet can message an existing Claude Code session, but it can't create a new one itself; new sessions have to be started manually from the phone app.
Because the session lives on your computer, editing a video from a phone means sending a short instruction and getting a new version link back.
Shipping to production from a phone works when the target project already has a running Claude Code session to receive the message.
Claude Code's computer use can be triggered remotely, which lets a phone ask a desktop to open an app and send back a screenshot.
The speaker rates Claude's computer use as not close to Codex's, so remote control is convenient but not the strongest option for GUI-heavy work.
The whole setup depends on the host machine staying awake, so a keep-awake utility and wall power are part of the requirement.
Messaging a session from Duet triggers an approval prompt, with Face ID on the phone, before anything is sent to your computer.
Real-time voice in Duet can dispatch instructions to multiple Claude Code sessions, then show the exchange as a transcript afterward.
Most developers already keep their code and project files local, so a phone link to those sessions beats re-hosting the work in the cloud.
Takeaway
Your phone can drive your real dev machine
WHAT TO LEARN
The value of Duet's update is not the cloud agent but the bridge: your phone can now steer Claude Code sessions on the powerful computer you already own.
A cloud agent handles light tasks, while your own computer handles heavy ones, so linking the two gives you both without moving your work online.
Messaging an existing session keeps its context, which is why asking for a new version of a video works so well from a phone.
New sessions can't be started by Duet itself, so start them manually from the app's session button and then hand off follow-up work by chat.
Remote workflows depend on an always-on host, so a keep-awake tool and wall power are part of the setup, not an optional extra.
Computer use through Claude Code is convenient for quick screenshots and clicks, but the speaker rates it well behind Codex for serious control.
Approval prompts and Face ID before a message reaches your computer are the safety layer that keeps remote control from being a blank check.

So this is actually huge. Claude Duet might have just taken the lead in the agent race with their latest update. Not only is Claude Duet powered by Opus 5 .5, as of yesterday, it can connect directly to Claude Code running on my computer and even spin up new Claude Code sessions.
And I don't think people quite grasp how useful this is. And so the first reason that this announcement is useful is that you now have an agent with a virtual... computer and a physical computer.
So this right here is the Claude Duet app. which is a brand new agent platform created by Anthropic. And it's not in the Claude app.
It is in a new separate app called Claude Duet. So now when I use Claude Duet, I can now ask it to spin up Claude code sessions running on my computer. And remember, Duet is Anthropic's version of Dots, Muse, and Grokbot, which is this new type of agent platform or a personal agent platform that has a persistent computer running in the cloud.
So it can act like a full employee with its own computer. However, I have a perfectly good MacBook Pro with 48 gigabytes of RAM that is constantly running cloud code for all my coding work, all of my video editing, and basically all of my planning and so many other tasks. Well, now you can use your little persistent agent for simple tasks, and then you can use your actual computer and you can actually set it up to multiple computers.
so that you can run Claude Code. Let me show you an example. So here is Claude Duet that I can access from anywhere.
Let's imagine I'm out at a coffee shop and I don't want to bring my laptop or my Mac Mini. I can just bring my phone. As long as I leave my computer on, I could be like, hey, what Claude Code sessions have we worked on in the past 24 hours on my MacBook Pro and my Mac Mini if that's on?
Look at this, 10 Cloud Code sessions were active on your Macs in the past 24 hours. The newest first, here are all of the sessions. And so in order to see your local sessions, they have its own dedicated button here at the bottom.
And this is a brand new button that you can click on that shows me my... Claude Code sessions. And if I scroll down here, I have two computers that I can connect to right now to run Claude Code.
I have Mac Mini, which is running behind me, and I have a MacBook Pro that is running right here. I can connect to both of them. So let me show you how this works.
Hey, remember we were editing that video earlier? I think it was yesterday, the vertical video about Claude Duet. Yeah, I want to continue working on that.
I'm working on it on my MacBook Pro. It's in a Claude Code session.
Yes, it's vertical video. Its latest cut is V2. So I can open up this link right here.
I can open up this link and I can see my latest version. So this is version three of my video. This is the coolest update to Claude in a very long time.
So Claude Duet can now connect to Claude Code. For those of you who don't know, Claude recently got rid of their product, Claude Cowork, and they actually added a new gen. And this actually brings me to the second reason why this is so useful, which is it is the best way to edit videos from your phone.
Let's say I wanted this to actually be a little bit faster. And there's this, this blender shot.
And so what I can say is I can just hit this X. Hey, I want you to make a new version of this video. And I want you to, in the opening scene, show the same blender shot that we show a little bit later.
And then I want this to be at 1 .1 X speed. compared to what it is now, just to be a little bit faster. So please make an update to this video and then send me the new v2 .video link.
And so now it's going to send this to a Cloud Code session that's running on my computer. So I could be traveling. I could be on a flight with a little internet access and I could be editing videos on my computer.
And so I always have a Mac computer running so that I can access Cloud Code no matter where I am. That's how much I use Cloud Code. And you can see here it says sent to vertical video edit with Blender graphics.
So that's the name of the existing session on Cloud Code. If we go over here and we find that identical title, we click on it. Here you can see that it is working right now within that session.
So we are basically communicating with that Cloud Code session from our phone. And remember, this is how you work with an existing session. If you try and create a new session on Cloud Code by talking to Duet, it won't work.
You actually have to do it manually from your phone. If you click on this button right here and you click new session, you can see the computers that you have access to. So I can create it in my Mac mini, which is right running right behind me in documents, or I can run it on my documents folder right here.
And then you just type your first message. And so you could just say, we're going to be editing a video. And so we can start this session.
And this will actually start this session running on my computer. And once it establishes a connection, you'll see this little green dot. And it says ready when you are.
If we scroll over to Cloud Code, right? We're in the Cloud Code tab. We click on this.
You can see that we started a session on this computer. So I can pick it up. when we get back.
So that's why you should always have your computer on because you can always start a new Cloud Code session or you can talk to your existing sessions. And so we can actually see the thread by clicking on here and it should actually be done. And so you can see here that the video was uploaded to V2.
So I can open this up. So let's see if it made those changes to that video. This is the coolest update to Claude in a very long time.
So Claude Duet can now connect to Claude Code. For those of you who don't know, Claude recently got rid of their... You see that?
On version 3 of the video, this is how it started. This is the coolest update to Claude in a very long time. And here was the update that I made from my phone using Claude Code running on my computer.
All I had to do was talk to Duet. This is the coolest update to Claude in a very long time. So Claude Duet can now connect to.
And that is how I edit videos now from my phone. So the third reason this new update is so useful is this is the best way to build apps directly. from your phone.
Hey, we were working on the Agent Native app or agentnative .inc. I want to make an alternative style. And so at the top of the screen, I want to be able to change it to a new alternative style that is kind of the same styles of Anthropic.
And so I want you to update the app and then push it to prod. Please just make the changes to the site. And yeah, let's update our new app and get it in production.
And so this is me just talking in the same chat. Oh yeah, do this on my MacBook Pro.
I have a session running for this. And there you go. Claude wants to message one of your Claude Code sessions or co -work tasks.
And there you go. And it will send this message to agentnative .inc. That's the name.
And it's running on my computer. So I'm going to go ahead and hit Allow. And now it wants to use Face ID.
That's very interesting. And there you go. Now it is running on Cloud Code.
I can see the full session right here and now we'll wait for it to finish and then it should be pushed directly to production. Okay, so let's see if Cloud Code that is running on my MacBook Pro at home is done. So if we scroll up here, we can see that there is a live link.
Apparently there's a hidden switch in the top bar. So this is live in production and I can press this button. Okay, so it just added this light mode.
to the app or to the website, which is really cool. So now you can vibe code directly from your phone and you can connect to Claude code running on your computer. Most people have all of their coding work local on their computer anyway.
So now you can do it from your phone. Just got to keep your laptop on. And the fourth reason that this is incredibly useful is now you can use computer use directly from your phone.
And you know how when you use Cloud Code, you can have it fully control your computer through computer use. And just to show you a very simple example in Cloud Code, I could say, hey, can you go to Descript and take a screenshot real quick and show me what it looks like in Descript?
Use computer use.
And there you go. You can see that it took a screenshot of Descript. And it can basically fully control your computer and click through things.
I will say it's not quite as good as Codex computer use. And if I'm being honest, it's actually not even close to as good as Codex computer use. But this does allow you to spin up new Codex sessions that can control your computer.
So that means from your phone, you can ask it to... use computer use and it can do that. And this gives you full control over your computer as long as it's on.
And just a very quick tip for keeping your computer on, you can use something called amphetamine. And amphetamine is a little app that allows you to keep your laptop on all the time and it will not allow it to go to sleep if you're running a session. So once you install amphetamine and it's completely free, you can download it in the app store and you create a new session indefinitely.
This means my computer will never go to sleep. And as long as it's plugged into power, we are good to go. I have my laptop on 24 seven.
I always have access to my 48 gigabyte Ram MacBook Pro M4, which is an amazing thing to have access to at any time. And then finally the fifth and final reason why this update is so useful is you now have real time voice. With Cloud Code.
So we are here in the app. Let's go ahead and go to our main session. I'm going to hit talk.
Hey, you know the session where we were building our app, editing our video? I want you to make one more version of the video with light music in the background, please. Can you do that?
It's on one of my existing Cloud Code sessions.
Okay, so now I'm just going to approve. I just hit approve. I just hit approve.
And so cool. Now you can chat with an agent and here it shows the conversation once you leave that little phone call. But here it says sent to vertical video with Blender for graphics.
If we navigate to cloud code, you can see here that this one. is indeed working. So I can, with real -time voice, communicate with multiple Claude Code sessions running on my computer.
Again, that is really, really cool. Anyway, I'm going to dive way deeper into this and learn as much as I can, and I'll be making another video for sure. So make sure to subscribe for that.
And by the way, the project that I was talking about earlier called V2, which is like the GitHub for video editing, allows you to create versions of your video and it saves them in the cloud. This is a project that I'm working on and I'm trying to work with cloud providers to make this free. to use for everyone.
I want people to get access to this for free and I'm going to be open sourcing it in two weeks. So you can actually sign up at v2 .video and this is the GitHub for video editing. I'm going to be making a lot of changes on this soon.
My team and I have been working really hard on this and I will keep you guys updated on it. So thank you guys so much for watching. I'll see you here in the next.
