Hey Product Hunt! 👋 I'm Ang, co-founder and CEO of Simular. We believe in a future where you’re no longer stuck in front of a computer—because computers will work for you.

That’s the future of work. And we’re building it.

Today, we’re beyond excited to introduce Agent S2, the next big step in autonomous AI agents that use computers like humans do—with a mouse and keyboard, navigating apps, websites, and software just like you would.

🤖 What is Agent S2?

Agent S2 is an autonomous AI that can use any software, website, or device just like you do—navigating with a mouse and keyboard, understanding screens visually, and completing digital tasks on its own. Imagine an AI that can organize files, edit images, manage spreadsheets, or even book your flights—all without you lifting a finger.

🔥 What Makes It Special?

✅ #1 in OSWorld Computer Use – Agent S2 achieves a new state-of-the-art with 34.5% accuracy in 50-step tasks, surpassing OpenAI’s Operator (32.6%). This proves that Agent S2 not only takes more precise actions but also improves over long, complex tasks—crucial for real-world automation.

✅ #1 in AndroidWorld Smartphone Use – Agent S2 dominates smartphone automation with 50% accuracy, outperforming the previous best model, ByteDance UI-TARS (46.8%). This shows that Agent S2 generalizes across platforms, making it one of the most flexible AI agents available.

✅ Fully Open-Source & Free to Use – You can start building with Agent S2 today! Whether you’re an individual developer or a company looking to scale automation, Agent S2 is open, modular, and adaptable to your needs. Join the community, contribute, and help push the boundaries of AI-driven automation.

🧠 The Future of Work: Autonomous Computers

At Simular, we’re a team of tech-driven people pushing the boundaries of autonomous agents and automation. Our goal? To free humans from repetitive digital tasks and let AI handle computers for you.

We built Agent S2 with a modular, scalable approach, inspired by the human brain—leveraging the best AI models in planning, perception, and action. This isn’t just another automation tool. It’s a true digital teammate that learns, adapts, and evolves.

Agent S2 is fully open-source and free to use, meaning you can integrate it, extend it, and build scalable applications with it today. We built it with a modular, scalable approach, inspired by the human brain—leveraging the best AI models in planning, perception, and action.

💡 Start Building with Agent S2

This is just the beginning. If you believe in a world where computers work for you, come try Agent S2 and help us shape the next frontier of AI-powered automation.

Agent S2 is a game-changer for human-computer interaction. It’s taking things to the next level, where we can all have personal assistants that handle everyday tasks, giving us more time to focus on what really matters.

Plus, it’s a huge step toward making technology more accessible—people with physical limitations or those who aren’t as tech-savvy will be able to easily use computers with Agent S’s help.

I am excited to see how Agent S will evolve and transform the way we interact with the digital world in the future.👏🏼👏🏼👏🏼

Big Fan of Agent S and the Simular team!

The only agent that really works for all that I have tried!

Agent S2 is seriously impressive—it’s like having a super-smart assistant who can handle everything for the work. What blows me away is how it works seamlessly for multiple tasks, and the fact that it’s open-source means you can customize it to fit your needs. If you’re tired of repetitive digital tasks, this is the AI you’ve been waiting for.

I can't believe AI agent is gradually becoming real. Congratulations!

Hello World! I'm JC, fellow maker at Simular with Ang and our great team here. It is exciting to achieve #1 on OSWorld and AndroidWorld, but we are even more eager to see the open-source community build on it to further heights. That is made possible by the intentional modularity of Agent S2, which allows the integration of any modules that you want for perception, planning, controllers, and memory. Join our mission to solve intelligence in the digital world!

Agent S2 impressed me with its accuracy and ability to correct its actions during task execution. I was especially pleased that it performs excellently on both computers and smartphones, making it a versatile solution for different platforms. It would be great if more customization options were added to tailor the agent's actions to specific tasks. Overall, my impressions are very positive!

well, I was pleasantly surprised with Agent s2 ability to handle complex digital tasks independently, from organizing files to booking flights. Its flexibility across platforms and open-source nature make it a powerful tool for both personal and professional automation.
