What is Sai?

Sai is Simular's computer-use agent that operates a cloud VM or your own device through the screen, handling recurring tasks across browsers and desktop apps. Runs can be scheduled, watched live and approved remotely.

Sai is a computer-use agent from Simular that operates a computer the way a person would. It runs on a private cloud virtual machine or on the user's own device, and it clicks, types and navigates through browsers, desktop applications, file systems and terminals. Because it works from what is visible on screen, it can handle software that offers no API, which is where many automation tools stop. The product is aimed at business professionals, founders, researchers and non-technical users who lose hours to repetitive screen work. Typical jobs named on the site include research, lead sourcing, follow-up drafting, scheduling, file organization, spreadsheet updates, document handling and recurring reporting. Separate solution pages cover sales, finance, marketing, operations, small teams and enterprise buyers. In practice, a user describes a task in plain language and Sai carries it out inside its own workspace while the user can watch the computer work. Important actions can require approval, and notifications arrive through iMessage, SMS or Telegram, so work can continue after the laptop is closed. The central idea is teach once, rerun on a schedule: the vendor says repeated tasks become faster and cheaper over time, drawing on its neurosymbolic research. The cloud VM keeps logins, preferences and context between sessions, and a bring-your-own-device mode supports Mac mini, macOS and Windows machines. Skills let teams extend behavior and share the most effective ones. Among alternatives, Sai competes with other general-purpose agents such as Claude Cowork, Perplexity Computer and OpenClaw, and with browser-only automation or API-based workflow tools. Its stated differences are a secure dedicated workspace, GUI-level control beyond the browser, approval-based oversight and always-on background execution. Teams that mostly need API integrations may find simpler tools sufficient, while those dealing with legacy or closed software are the natural fit. An API is also offered through the Simular platform for developers.

How do you use Sai?

1Open Sai and start a workspace
Use the Try Sai button on the homepage to enter the app. Sai provides a private cloud VM, or the user can switch to their own device.
2Check plans before committing
Review the pricing page to see which plan suits an individual or a team before running recurring workloads.
3Describe a task in plain English
Type the outcome wanted, such as updating a spreadsheet or drafting follow-ups. Sai performs the steps inside its workspace.
4Watch the run and approve key steps
Follow the computer live to see what it does, and approve critical actions when prompted. Alerts can arrive through iMessage, SMS or Telegram.
5Schedule the task to repeat
Once a workflow runs well, set it to rerun on a schedule so recurring reports and chores happen unattended.
6Explore role-specific use cases
Browse the solution pages for sales, finance, marketing or operations to find workflows matching your team.
