Perplexity Comet

Perplexity Comet is an AI-powered browser that redefines how you interact with the web. It integrates Perplexity's answer engine and a proactive assistant directly into the browsing interface, allowing you to delegate tasks like research, comparison shopping, and data extraction.

What Perplexity Comet does:

• •Agent Mode automates web tasks The assistant can autonomously navigate websites, click buttons, fill forms, and extract information to complete multi-step workflows like research or online shopping.
• •Inline Assistant interacts with any page Highlight text or ask questions directly on any webpage to get instant summaries, translations, or explanations without leaving the tab.
• •Research Mode provides cited answers Get detailed, citation-rich answers to complex questions by leveraging Perplexity's real-time search and web indexing capabilities.
• •Browser Extension adds AI anywhere Install the Comet extension to access the assistant's core features from within other browsers like Chrome or Firefox.
• •MCP Support connects to external tools Use the Model Context Protocol to connect Comet to other AI models and tools, expanding its capabilities beyond Perplexity's native engine.
• •Cross-platform availability Use Comet on desktop (macOS, Windows) and mobile (Android via the dedicated app) for a consistent AI-assisted experience.
• •Creates content from prompts The assistant can draft emails, generate website outlines, or create study plans based on your instructions and web context.
• •Compares information side-by-side Automatically gather data from multiple sources and present a synthesized comparison, useful for product research or trip planning.

Limitations:

• •Serious Security Vulnerabilities Disclosed in Early 2026 — Security researchers discovered the 'PerplexedBrowser' vulnerability, where a standard calendar invite could trigger a zero-click attack forcing Comet's AI agent to read local device files and exfiltrate data from password managers. A separate 'CometJacking' exploit allowed malicious URLs to hijack the browser's AI to autonomously siphon Gmail data. These are verified, publicly disclosed risks — not theoretical.
• •Crashed After Launch and Remains Unstable — Comet launched to significant hype and briefly hit #3 on the iOS App Store in early 2026, then plummeted to 'Not Ranked' within weeks after widespread reports of crashes and broken sign-in flows. As of April 2026, platform stability remains a concern for users needing a reliable daily browser.
• •No Cross-Device Sync — Bookmarks, passwords, and settings are stored locally and do not sync across devices. If you work from both a laptop and a desktop, or share a workflow with colleagues, none of your data follows you — a fundamental limitation for anyone using Comet as a primary browser.
• •AI Agent Fails on Complex Real-World Tasks — The AI assistant loops and fails regularly on multi-step tasks like booking reservations, completing checkouts, or filling multi-field forms. One early tester documented the same restaurant booking attempt failing three times before the agent gave up entirely.
• •Federal Court Ordered Halt on Automated Purchases — In March 2026, a US federal court ordered Perplexity to stop Comet's AI from making automated purchases on Amazon, citing computer fraud allegations. This permanently caps one of the product's headline use cases.
