Overview
ego is a personal AI agent designed to live across your browser, desktop, and phone. It learns from your conversations, browsing habits, and desktop activity to build persistent memory and skills. ego can run multiple complex tasks in parallel 24/7—such as research, report generation, email replies, app building, and competitive analysis—and deliver finished files directly to your computer. It works through multiple interfaces: an AI browser, a desktop agent, a Dynamic Island on iPhone, iMessage, and voice commands.
Qursor is a Chrome browser extension focused on UI inspection and annotation. It allows you to hover over any element on a webpage to instantly see its fonts, colors, spacing, padding, and margins. You can click to edit styles directly or annotate what should change, then copy structured context (selectors, classes, styles) to paste into your AI agent. Qursor also lets you extract components as HTML, CSS, or JSX, download assets, pick colors, and detect fonts—all without opening DevTools.
