AI Browser: Comet

I. Executive Summary: Strategic Insights into the AI Agent Browser Comet

Comet browser, launched by Perplexity AI, a leader in the field of AI search, represents a fundamental turning point in the history of web browsing tools. It marks the shift of the browser paradigm from traditional information retrieval tools to task execution agents (Agentic Executor). Comet's core value lies in its AI agent capability — Comet Assistant can autonomously execute complex tasks across multiple websites and applications, such as online shopping, schedule planning, data analysis, and even basic website building¹.

1.1 Key Findings and Strategic Points

Professional analysis of Comet reveals its disruptive technological core and the accompanying high risks:

1. Disruptive technological core: Comet focuses on agentic action, which is fundamentally different from the "smart assistant" browsers currently on the market that provide page summaries or built-in chat (such as Arc Search)². Comet is designed to take over and automate user workflows.
2. Business model focus: The browser itself is a free traffic gateway. Perplexity's monetization strategy is to strictly bundle Comet's core agent capabilities and access to advanced AI models (such as GPT-5 Thinking, Opus 4.1) into high-value Pro/Max subscription tiers³. Comet serves as an efficient access layer (Access Layer), designed to convert ordinary users into high ARPU professional subscribers.
3. Key risks and compliance challenges: Comet's agent deliberately does not disclose its identity when performing tasks, which is the biggest obstacle to its business model. Amazon's lawsuit against Perplexity, accusing Comet of covert access and impersonating human browsing, fully exposes the compliance risks of AI agent tools in e-commerce and data security⁵.
4. Content ecosystem impact: By mimicking the digital ID of a standard human user, Comet can bypass the traditional Robots Exclusion Protocol and content paywalls, thereby obtaining the full text of subscription-only articles⁷. This poses an existential threat to the digital content publishing industry that relies on paid subscription models.
