Key features
Perplexity Comet
An agentic browser that answers questions and takes action across tabs
Weaknesses
- Con: Security researchers at Brave demonstrated that Comet's assistant is vulnerable to indirect prompt injection, where hidden instructions planted in an ordinary webpage can hijack the agent to read your email, pull one-time passcodes, and exfiltrate data using your own logged-in privileges.
- Con: Perplexity initially dismissed the disclosed CometJacking data-exfiltration flaw as having no security impact before quietly patching it, which raises questions about how the vendor handles vulnerability reports on an agent that operates across your authenticated sessions.
- Con: Mobile support is still immature because Android access only arrived in November 2025 and iOS not until March 2026, well behind the July 2025 desktop launch.
- Con: The full agentic capabilities depend on Perplexity's own AI stack and subscription tiers, so buyers wanting a neutral browser or a different underlying model will find themselves locked into Perplexity's ecosystem.
