Hatch a little Sai computer. Each robo character represents a real computer hard at work.

What is Sai?

Sai turns any computer — a private cloud VM or your own device — into a self-operating machine.

The computer-use agent (CUA) reasons and acts inside real interfaces, clicking and typing through browsers and desktop apps exactly like you would, but tirelessly. Every run gets faster and cheaper than the one before.

Backed by best-in-class computer-use agent research

Trusted by users across industries

Sai for Teams

Free your team from the busywork.

The work that nobody on your team should be doing by hand. Sai runs it 24/7.

Cost-efficiency over time

Sai learns from every task and doesn't make you pay twice for repeated work, using Simular's (parent company) neurosymbolic research. Repeated tasks get faster and cheaper over time.

Full desktop automation, not just the browser

Most AI agents are trapped inside a web page. Sai works across your entire operating system: desktop apps, web browsers, file systems, and terminals, the way a human would.

GUI-based workflows, handle software even without APIs

Sai sees the screen the way you do. Because it understands interfaces through graphic interface, it isn't limited to API automation. If you can click it, Sai can.

Run on a cloud desktop, close your laptop

Sai lives in its own cloud virtual machine, so tasks don't need your laptop open. Command Sai through your phone on the go. Switch to BYOD when you need.

Persistent memory — Sai remembers your setup

Sai's virtual machine is your own permanent environment with memory. Your setup, logins, preferences, and context persist between sessions.

Questions, answered.

What is Sai?

Sai is your autonomous computer -- a computer-use agent (CUA) that turns a private cloud VM or your own device into one that operates itself. Sai reasons and acts inside real interfaces, clicking and typing through browsers and desktop apps exactly like you would, but tirelessly. Just describe what you need in plain language, and Sai gets it done with full transparency and built-in safety guardrails.

Any agent can do a task once. Sai does it every day, unattended, and gets better and faster each run.

Our vision is to free humans from mundane computer work so they can get back to what matters.

Who is Sai for?

Sai is for anyone stuck doing repetitive, time-consuming computer tasks. Business professionals, founders, researchers, and non-technical users alike use it as a personal AI assistant that does more than answer questions -- it actually gets work done.

What can I use Sai for?

You can use Sai for a wide range of digital workflows, including research, lead sourcing, follow-up drafting, scheduling, file organization, spreadsheet updates, document handling, recurring reporting, and other repetitive work across apps and websites.

How is Sai different from Claude Cowork, Perplexity Computer, OpenClaw, and other AI agents?

Sai is designed around four core differentiators:

A secure workspace where the AI works
GUI-based computer use, not just browser or API actions
Approval-based control for important actions
Always-on background execution so work can continue while you do other things

What does BYOD mean in Sai?

BYOD stands for Bring Your Own Device. In Sai, BYOD means you can use your own device environment to access Sai's capabilities instead of relying only on the default setup.

How do I start using Sai?

Sai is designed to help users get started quickly without complex setup. You can give Sai a task, choose a workflow, or describe the outcome you want -- all in plain English, and Sai will work inside its secure workspace.

Does Sai support skills?

Yes. Sai supports skills, so you can extend how it works for different tasks and workflows. This makes it easier to adapt Sai to more specific use cases rather than relying only on one default behavior.
