Sai is an always-on agentic AI coworker that can actually do work on a computer for you. Sai can use apps, websites, and desktop interfaces, navigating the graphic user interface (GUI) like humans do. It combines the behavior of an AI agent, an AI personal assistant, and a workflow automation tool in one product. Our vision is to free humans from mundane computer work so they can get back to what matters.

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. Sai is especially useful for tasks that require real computer interaction.

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, and always-on background execution so work can continue while you do other things. Sai is built to support broader digital work by combining browser, desktop GUI, terminal, and tool-based workflows in one system, while keeping users in control through live visibility and approvals.

What is a GUI-based agent?

A GUI-based agent is an AI agent that can interact with the graphical user interface of software, meaning it can work with buttons, menus, windows, text fields, and other visible elements on a computer screen. Instead of relying only on APIs or text commands, a GUI-based agent can operate software the way a human user does. Simular's agentic framework Agent S was the first to outperform human performance on the OSWorld benchmark.

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. Sai's BYOD supports devices including Mac mini, macOS and Windows.

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. It also supercharges collaboration with the most effective skill shared across a team.

Is Sai safe for business workflows?

Sai is built with production-grade, enterprise use in mind, with a dedicated digital workspace, approval flows, and live visibility that give teams the safety and oversight of real business demands.
