Perplexity Comet

חסרונות

• Serious security exposure: vulnerable to prompt-injection 'CometJacking' attacks that hijack the agent via malicious URLs to exfiltrate email/calendar data
• Independent testing (LayerX research, 2025) found it up to 85% more susceptible to phishing and web attacks than Chrome; researchers tricked it into completing a phishing flow in under four minutes
• Granting the agent inbox/calendar/file access removes human checkpoints and creates a large attack surface across authenticated sessions
• Perplexity has stated a motive of collecting data 'outside the app to better understand you,' raising privacy concerns
• Agent reliability is uneven on complex multi-step tasks and it competes against entrenched browsers
