Description

Underdog is a private, local AI assistant for Mac that handles email, calendar, and task management entirely on-device, aimed at users who want AI help with day-to-day organization without their email and calendar data leaving their machine to a cloud service. It is aimed at privacy-conscious Mac users who want AI productivity help without a cloud-based assistant reading their inbox and calendar.

Adept AI builds action-oriented AI agents, headlined by its ACT-1 Action Transformer, that perceive on-screen interfaces and carry out multi-step digital tasks such as navigating apps, clicking, typing, extracting data, and filling forms from natural-language instructions. It targets enterprise operations teams in areas like supply chain, financial services, and healthcare that want to automate repetitive software workflows across tools such as Salesforce and Excel. Unlike script-based RPA, it reasons about screen state visually and adapts its plan after each action rather than following brittle predefined macros.
