Perplexity challenges Google with its own AI browser “Comet”

While conventional browsers like Chrome or Safari are primarily tools for viewing web pages, Comet positions itself as an “AI-native” browser. This means that artificial intelligence isn’t just an added feature (like Copilot in Edge), but rather the core of the software.

Following its desktop launch, Perplexity is now rolling out the browser to mobile devices (Android launch in November 2025, iOS to follow). The goal: to transform browsing from a passive activity (“I’m reading a page”) to active assistance (“The AI ​​is doing something for me”).

The 3 Core Features at a Glance

The “Comet Assistant” (Agent AI): The most important unique selling point. The browser acts as an agent. It can not only answer questions but also perform context-related tasks.

Example: You have 10 tabs open with different product reviews. Instead of reading everything, ask Comet: “Summarize the pros and cons of all these open tabs and tell me which product costs under €50.”

Voice-First Navigation: Especially on smartphones, Comet relies heavily on voice input. The “Voice Mode” allows you to conduct complex research completely hands-free. The interaction feels more like a conversation than typing keywords into a URL bar.

Security & Control for High-Stakes Actions: A major problem with AI agents is “hallucinating” or unwanted actions. Perplexity has built in security mechanisms to address this: If the assistant is supposed to perform sensitive actions (e.g., logging into a website or adding items to a shopping cart), the system pauses and explicitly requests the user’s permission.

For Perplexity, its own browser is a strategic move to break free from dependence on other platforms.

Battle for the Homepage: Whoever controls the browser controls access to the internet. Until now, Perplexity had to rely on users actively visiting its website. With Comet, Perplexity becomes the default interface.

Competition to “Arc” and OpenAI: Perplexity isn’t alone. The “Arc” browser (from The Browser Company) has already demonstrated what an AI browser can look like. OpenAI (ChatGPT) is also rumored to have similar browser ambitions. Perplexity is now trying to establish itself as the faster, research-oriented alternative.

Important to Know: While Google Chrome primarily earns its money through advertising, Perplexity uses a freemium model. Basic use is free, but a Pro subscription is required for deeper analyses and more advanced AI models (such as Claude or GPT-4o).

Availability of the Perplexity Comet Browser:

• Desktop (Mac/Windows): Already available.
• Android: Rolling out since the end of 2025.
• iOS (iPhone/iPad): According to the company, available soon.
