Simular is building the world’s first autonomous computers—systems that can use software like humans do.
From browsing websites and filling out spreadsheets to running creative tools and managing workflows, Simular enables a new era of human-computer interaction where software operates itself.
Whether you’re a solo founder, a global enterprise, or an AI researcher, Simular gives you access to the future of computing: computers that think, act, and get things done—autonomously.
This is the 5th launch from Simular. View more
Sai
Launched this week
Sai is the world's first robosecretary that works with a fleet of autonomous computers, doing your endless screen work. Each computer navigates software the way you do: reads the screen, clicks the button, types in the form. Trained to interact with the computer interface, Sai automates software even when they lack APIs: legacy desktop apps, internal portals, anything behind a login. Sai supports Windows, macOS and Linux. 73% on OSWorld.

Do you see this replacing RPA tools or is it a different category entirely?
Simular
@sophietech it's a different category but RPA will evolve towards this direction as well

I've been waiting for something like this that doesn't need a ton of setup just to automate basic desktop tasks, hope it delivers
Simular
@mi_leeli Definitely give it a try! Would love to hear how it works for your use case 🙌

Congrats on the launch, @justin2025 ! If Sai gets better at my usual file names and checks over time, that could save a surprising amount of setup.
Simular
@power_valsha That’s exactly the idea! Less setup every time you come back to the same workflow. Give it a try and let us know how it goes! 🙌

My work rarely stays in one tab. I go from email to a native app to a spreadsheet just to finish one request. If Sai is able to work across the desktop, then it will be very useful to me.
Simular
@lavana_cricko Hi Lavana, that's exactly the workflow Sai is built for. It operates at the OS level instead of through app-specific APIs, so it can move from your inbox to a native app to a spreadsheet in the same session, the same way you would.

Hey PH — I'm Richard (Chih-Lun), part of the crew helping ship Sai.
It's been fascinating to watch the evolution: local machines, then a shared VM, then dedicated VMs for each of us, and now a full agent fleet for everyone.
Huge thanks to everyone who helped get this out the door. Really grateful to have been part of it.
I like that it remembers how I like things done instead of making me re-explain every time, which saves token usage a lot.
Typeless
Being able to choose local or cloud makes this much more useful.
