What if you could delegate your most time-consuming tasks to a team of tireless, hyper-efficient assistants, all without hiring a single person? Enter Perplexity Comet, an innovative AI-powered browser that's reshaping how professionals approach their daily workflows. With its ability to handle everything from real-time competitor analysis to SEO optimization, this tool doesn't just automate, it transforms. Imagine a world where your research organizes itself, your sales leads find you, and your content practically writes itself.
To the surprise of no one in the security industry, processing untrusted, unvalidated input is a bad idea. Until about a week ago, Perplexity's AI-based Comet browser did just that - asked to summarize a web page, the AI-powered browser would ingest the text on the page, no questions asked, and process it. And if the page text - visible or hidden - happened to include malicious instructions, Comet would attempt to comply, carrying out what's known as an indirect prompt injection attack.
In July 2025, Perplexity launched Comet, a groundbreaking AI-powered web browser designed from the ground up for this era of intelligent automation. Comet integrates intelligence at its core, transforming browsing sessions into seamless, conversational workflows.
