Perplexity Comet is a genuinely strong browser agent, cross-platform, free tier, good at research and tab synthesis. But every agent works through a control surface, and Comet's surface is the browser session itself: tabs, webpages, browser-accessible documents. The moment a task needs a native app, a desktop tool, or a phone's system dialog, that's a different interface boundary.

The piece covers where that boundary actually shows up in real workflows, situates Aiden against the wider category of browser agents (Fellou, Dia, Opera Neon, not just Comet), and explains Aiden's own approach: a physical device that observes a connected screen through HDMI capture and sends input through USB HID, no app-specific integration, no jailbreak required.
