Sai is an AI robosecretary built by Simular that runs a fleet of autonomous computers to organize, execute, and repeat work across apps, websites, and desktop software. Give it permission to handle routine, multi-step tasks while you focus on higher-level work.
What it does
Sai acts as a computer-use agent: it operates real interfaces the way a person would, clicking and typing through browsers and desktop apps to complete tasks end to end. Instead of a single one-off automation, Sai can be taught a workflow once and rerun it repeatedly, getting more reliable and efficient with each run. It works across apps and websites that don't expose clean APIs, and it can run on a private cloud computer so tasks continue even when your own laptop is closed.
Who it's for
Sai is built for individuals and teams looking to automate multi-step computer workflows: busy professionals, founders, researchers, and non-technical users who are stuck doing repetitive, time-consuming computer tasks. It fits especially well for recurring work — a report rebuilt every month, a process that spans tools that don't talk to each other, or a task run every week.
Pricing & access
Sai offers a free Explore tier with a daily credit allowance and limited access to a cloud-based computer, so anyone can try it and build a first workflow. Paid plans add more credits, dedicated cloud computers, and unlimited usage for people who run Sai regularly, and an Enterprise plan is available for organizations that need managed scaling, SSO, and custom integrations.

Quick answers
Is Sai only a browser bot? No — Sai combines browser, desktop GUI, terminal, and tool-based workflows in one system.
Do I need to code or use an API? No, tasks are described in plain language and Sai works inside its own secure workspace.
Can Sai run without my computer on? Yes, Sai can run on a private cloud computer so tasks continue in the background.
