[0:07]Welcome. Architecture like this is both visionary and engineered. That balance between creativity and system is what makes something special and scalable.
[0:18]That now applies to software in the same way. It's no longer just technical work. It's creative work. So today, we launched the next evolution of that idea, Replit Agent 4.
[0:31]Replit Agent 4 is built around four pillars engineered for the creative flow. Together, they unlock a new rhythm between imagination and implementation.
[0:42]You can build things up to 10 times faster, which means dramatically more time for your creative work.
[0:48]Over 50 million builders are using Replit to put their ideas to work. Every day, they're turning imagination into working software.
[0:57]Agent 4 pushes that further than ever before.
[1:03]In most tools, design and development live in separate worlds. You mark something up in one place, then rebuild it in another. Agent 4 changes that.
[1:10]For the first time, design and development now live in the same environment. You can explore ideas directly inside your working app, generate multiple design directions, compare them, refine them,
[1:22] and make precise changes to real UI and see those live. You don't leave the system to design, you design inside the system.
[1:30]Your ideas stay live, and you design freely. Let me show you how it works.
[1:36]Everyone's looking to work with people who really understand AI. So let's build a job marketplace that connects creative AI talent and helps that talent find the right roles.
[1:46]I'll start by asking the agent to create it. Create a job marketplace that helps companies find creative AI talent and helps that talent discover the right roles.
[1:54]Let's use the design canvas to iterate on design directions.
[2:00]Alright, so the agent generated four variants of the landing page. I kind of like this direction, but I would like it to be a little more elevated.
[2:09]So I'll select this variant and ask the agent to create a more premium-looking version.
[2:14]I like this new variant it generated. Now, I just want to change the color of this button, which I can do with the design controls on the right.
[2:23]Great, this looks good.
[2:29]Next, talented candidates come from all over the world, and I want to illustrate that in a visually compelling way.
[2:34]What if I had a globe animation that could go on the landing page? I'll ask the agent to make a 3D globe just like my sketch here.
[2:43]Nice, this is what it generated. I can select one of these geos and it'll give me more details on the candidate.
[2:48]Alright, let's take it to the app.
[2:52]The new design is now reflected on the live app. As you can see, I was able to design while the agent was building. So the flow is never interrupted.
[3:03]For way too long, development has been all too sequential. It made you work through one task at a time. We changed that rhythm. Agent 4 can move across your project in multiple places at once,
[3:14]working on multiple tasks in parallel. And when a task is too large, it doesn't block the system. It breaks it down, resolves each piece, and merges them safely.
[3:23]The result isn't just speed. It's scale. This is a massive milestone. So let me show you how it works.
[3:31]I'm going to add a bunch of new features to this app. For every feature, I can spin up a new chat thread, and multiple agents will build in parallel,
[3:39]working on tasks in the background at the same time.
[3:42]While it's building, I can go on to do the next thing.
[3:45]For example, I asked the agent to create a candidate profile to showcase their projects. While that's going, I don't have to wait. I can move on to the next thing.
[3:52]Then, I'll ask it to add a pricing page with different tiers.
[3:57]After that, I can prompt it to add matching functionality to recommend top candidates.
[4:03]Now, that's a lot. Let's see where it all went. We can look at our board where we can see an overview of everything we're working on.
[4:10]Each prompt gets listed as a separate draft with a plan for its completion. As you can see, I put in all my ideas, and as the agent figures out how to build it,
[4:19]I can go do other things. Creative acceleration means you don't have to wait. The system moves as fast as your ambition.
[4:27]Today, when you work as a group, you really end up managing the conversation instead of shaping your product. With Agent 4, we change that completely.
[4:35]So you can work as a real team together. You can see what's in progress, see who submitted the request, review what's done, and approve what moves forward.
[4:45]Now, let me show you what we've built in. I invited my team to join me in polishing the app. Here they are.
[4:51]Here we can see Zade and Vic are working on layouts on the design canvas. They're making design updates to different elements of the app at the same time in a collaborative workspace.
[5:01]That's very cool. Reina and Aman are entering prompts to build out more features at the same time.
[5:07]Reina prompts, add share functionality so candidates can share their profiles on social media. Aman prompts, build messaging functionality so companies can reach out to candidates.
[5:18]You can see the tasks that the agent is actively working on here.
[5:22]When a task is done, it moves to the ready pane. Once I review and approve a given task, it's applied to the main app.
[5:29]As you can see, creative collaboration means you stay focused on the vision while the system handles the coordination. The work moves forward without ever slowing you down.
[5:41]In most platforms, you can only create one type of thing. You build an app in one, a website in another, a deck in yet another.
[5:49]For the first time, in Agent 4, you can build everything in one place. Your apps, your data, your design, your context,
[5:59]in one change can apply everywhere. Let's have a look.
[6:03]Now that the web app's built, I want to build a mobile app. I don't have to leave this workspace or create a new app.
[6:09]I don't even have to describe the app again. I'll just say create a mobile app. While I wait for the agent to build this mobile app, I can get it started on some other tasks.
[6:18]I think this app has the potential to be a startup, and maybe raise some money. So I'll ask the agent to create a pitch deck to raise seed funding and to create an animated video to promote this app on social media.
[6:30]I'm going to ask the agent for both in one prompt. It will build them using the exact same contexts and design as the web app.
[6:37]And boom, here's the mobile app. I can look at it on my phone and then push it right to the app store. Alright, it's looking really nice.
[6:45]As you can see, everything is living in one place. My web app, my mobile app, my marketing material, and my pitch deck. It's pretty cool.
[6:53]But the coolest thing is that we're launching this app. If you're looking to hire AI native talents, or if you're a vibecoder looking for your next job, check out viberoles.com.
[7:02]Creative production means your work doesn't stop at the first version. Once you build something, you can turn it into anything, from websites, apps, decks to videos and animations.
[7:16]And that is Replit Agent 4. It's about creative agency. For the first time, agentic systems don't pull you out of the creative process.
[7:26]They move with you. The right system doesn't compete with vision. It gives it range. Agent 4 is built for that range. So your energy stays where it matters.
[7:35]On direction, on taste, on judgment, on the decisions only you as a human can make. When tools and execution move with you, ideas become real and turn into working products in minutes.
[7:49]That's why creativity runs on Replit. To everyone at Replit, the engineers, the designers, researchers, and builders who made this possible, thank you.
[7:59]Agent 4 removes the distance between imagination and reality. Design freely, move faster, build together, ship anything.
[8:08]And starting today, Agent 4 is available to anyone who wants to build. What happens next is defined by us. It's defined by what you create. Creativity runs on Replit, and now it runs with you.
