Product Overview
What is Sai?
Sai, built by Simular, is a computer-use agent that works like a human employee inside your existing software rather than producing instructions for you to follow. It clicks, types, scrolls, and navigates real desktop apps, browsers, and file systems on a dedicated cloud virtual machine or on the user's own Mac, Windows, or Linux device. Built on Simular's neurosymbolic Agent S research, Sai tops the OSWorld 2.0 benchmark for real-world computer tasks, outperforming general-purpose models like GPT-5.6 Sol while using significantly fewer tokens. It runs 24/7, remembers logins, preferences, and context across sessions, and hands back finished work instead of a to-do list.
Key Features
GUI-Native Computer Use
Operates desktop apps, browsers, and terminals through actual clicks, typing, and navigation, so it works with software that has no API, not just web pages.
Persistent Cloud VM
Runs on its own dedicated virtual machine with retained logins, files, and preferences, letting tasks continue after you close your laptop.
Cross-Device Flexibility
Can run on Simular's cloud infrastructure or directly on a user's own Mac, Windows, or Linux machine, with control available from a phone.
Neurosymbolic Reasoning Engine
Built on Agent S, an open research framework combining symbolic planning and neural perception to cut token usage by over 90% on long, multi-step tasks.
Approval-Based Controls
Lets users set checkpoints for sensitive actions, keeping a human in the loop for high-stakes or irreversible steps.
Simulang Scripting
An open-source scripting language for recording a workflow once and replaying it reliably across browsers, native apps, and OS-level tasks.
Use Cases
- Recurring Screen Work : Automates repetitive tasks like data entry, form filling, and report generation that would otherwise consume hours of manual attention each week.
- Cross-App Workflows : Completes multi-step processes that span several desktop and web applications without needing custom API integrations between them.
- Business Process Automation : Organizations with high volumes of repetitive computer tasks deploy Sai to handle back-office operations at lower cost than manual labor or brittle RPA scripts.
- Remote Task Delegation : Individuals assign tasks from a phone or another device while Sai executes them on a persistent cloud computer in the background.
- Legacy Software Automation : Handles interactions with older enterprise portals and desktop tools that lack modern APIs, using the same interface a human employee would.
