Simular Company Development

Agent S Research Reaches the Desktop

Simular's open-source Agent S framework explored how an agent can operate a graphical interface. Sai took that research into a desktop product, where a user's work may move across applications with no single API covering the whole task.

Simular Competitive Landscape

Desktop Agents and Browser Agents

A browser agent can operate on tasks already contained in web pages. A desktop agent needs to follow a user across windows and native applications as well. Simular's desktop focus makes this distinction central to which tasks it can take on.
