An incident showing Perplexity’s Comet browser completing an online course assignment in seconds has forced a public admonition from the company’s CEO and renewed scrutiny of agentic browsers on campus. Educators warned that agentic AI tools can be used to bypass learning objectives, while security researchers flagged vulnerabilities such as prompt injection and ‘CometJacking’ that can exfiltrate private data. Perplexity and other AI browser makers market agentic agents as study aids, but audits by security firms have exposed cases where the software can execute hidden webpage instructions or perform checkout flows without human verification. That combination of academic misuse and technical risk has prompted calls for campus policies that govern permitted tools, student use cases and vendor security standards. Universities must weigh open access to emerging tools against integrity controls, technical audits and faculty training to prevent misuse and data exposure.
