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
Launching today
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.

Hey ProductHunt,
I'm JC, representing the research team behind Sai.
We're releasing Sai for free --- to free everyone from the repetitive busywork of clicking and typing on a computer, so we can all spend time on more fulfilling, creative, and impactful work than operating a computer.
"Did you say free? Doesn't Sai use LLMs??"
Yes! Sai operates a fleet of autonomous computers for complex personal and business workflows. You delegate a task to Sai, and it orchestrates the best and most efficient models: reasoning models for pulling multiple documents from your Drive, state-of-the-art vision models to click on any pixel on the screen, and efficient verifiers to make sure each computer action is safe and correct for the task.
"Then how is free possible?!?"
You know what's better than using LLMs? Not using LLMs (at least not for everything). After Sai completes your task once, it learns to repeat the task with 10-100x cost savings in future runs, so we're able to release this free tier for a mass audience along with our paid tier for power users.
"Are the machines free also?"
Yes, Sai's free tier comes with one remote machine, dedicated just for you for 30min per day. We learned from our invite-only release of Sai since March 2026 that the majority of routine workflows can be completed within 30min per day of machine time. So we've optimized Sai's infrastructure so that you get a full personal machine just like your own.
"So how do I get started?"
Go to https://www.sai.work/, and Sai, your first robosecretary, will show you how autonomous computers live and work in a new digital world --- giving you more freedom in yours.

Sounds interesting! What's the difference to Codex or Manus?
Do you see this replacing RPA tools or is it a different category entirely?
NexaSDK for Mobile
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.
what happens if the app updates and the buttons move around, does it break or does it adapt?
@boyuan_deng1 Sai will adapt, it doesnt matter if the app changes it's layout, or changed the entire ux flow, Sai will figure out and get things done 😊

Being able to choose local or cloud makes this much more useful.
