Comet is Perplexity's agentic browser, designed to handle the research, comparison, and transactional tasks that ecommerce operators currently spread across 15 open tabs. It reads pages, fills forms, compares SKUs across retailers, and executes multi-step workflows on the user's behalf. For commerce leaders, it's relevant as both a productivity tool for internal teams and a signal of how AI-mediated shopping will reshape product discovery, attribution, and traffic patterns over the next cycle.
