Perplexity, the company known for its AI-based search engine, has taken another step in the browser wars with COMET, its new browser with an integrated assistant. The launch was announced on July 9, 2025, and is currently only available to subscribers of the $200/month Max plan and a small group of waitlisted users.
In this sense I have been fortunate to be able to try it 🙂
What makes COMET different and why should you be interested?
What is COMET?
COMET is a Chromium-based browser, so the interface is familiar to Chrome users. The big difference is its integrated AI assistant, Comet Assistant, which appears in a sidebar. This assistant is not a simple chatbot but a contextual agent that can read the page you are viewing and act on it. Its main functions include:
- Integration with Perplexity’s search engine: each new tab opens with Perplexity’s search, providing answers with quotes instead of a list of links
- Contextual assistant: the assistant can summarize articles or emails, suggest agenda settings, find data within dense sites, and ask clarifying questions. In addition, it remembers the context of each tab to follow the conversation even if you change pages.
- Agentic” navigation: you can ask it to navigate for you; for example, to group tabs, compose emails, or create Notion pages. This capability is aimed at turning the browser into a workspace that automates repetitive tasks.
- Application integration: COMET can interact with web editors (WordPress, Google Docs, Notion, Medium), productivity suites (Gmail, Google Calendar, Trello, Asana), commerce platforms (Amazon, eBay), and other AI tools such as ChatGPT or Claude.
- Multi-LLM support: from the sidebar, you can choose between models such as GPT-5, Claude Sonnet 4, Gemini Pro, or Grok. The Pro version of Perplexity unlocks unlimited use of the wizard and access to various models.
COMET puts AI at the center of the browsing experience. Stark Insider magazine describes it as “a Chrome with a brain” and notes that its assistant is really useful for summarizing mail threads, searching, writing replies, and updating apps like Notion
Benefits for digital marketing and ecommerce
The main advantages of using Comet are:
- Saving time in research. Instead of opening dozens of tabs to compare suppliers, specifications, or prices, COMET allows you to highlight information on a page and ask the wizard to compare it with another source. This reduces hours of research to a few minutes
- Mail and calendar management. The wizard can summarize inboxes and suggest meeting times based on your schedule. For a marketing consultant, this helps prioritize tasks and avoid missing opportunities.
- Content creation and localization. COMET allows you to rewrite or translate texts directly from the pages you visit, generating product descriptions or campaign copy adapted to different markets.
- Automation of routine tasks. You can group tabs, compose emails, synthesize meeting notes, and update documents, freeing up time for strategic tasks.
- Access to multiple AI models. The choice of GPT-5, Claude, Gemini, or Sonar allows you to experiment with different styles of content generation and choose the most appropriate for each case.
What are its limitations and what should we be aware of?
- Price and availability. COMET is in early stages and only accessible to Perplexity’s Max plan users or by invitation.. This limits its mass adoption in the short term
- Learning curve and reliability. Although the assistant is effective in simple tasks such as summarizing emails or planning trips, reviewers have pointed out that it fails in more complex actions such as booking trips or filling out forms, due to the “hallucinations” of the language models.
- Privacy and data access. To function, COMET requests extensive permissions on your email, calendar, and browsing. Flatline Agency reminds that, although the data is processed locally and is not used to train models, companies should evaluate the privacy and compliance implications before adopting it.
- Screen space and performance. The assistant occupies a side strip, which can be awkward on small screens, and some users have noticed a slight delay in navigation.
Comet Perplexity has taken a relevant leap into a new era in web browsing, where the browser becomes an intelligent assistant. The concept reminds me of OpenAI’s Operator, another browser experiment with an integrated agent.
I am preparing a demo on my YouTube channel where I will test Comet in real time and comment on whether it is really worth it. Would you dare to change your current navigator for one that uses AI as a co-pilot?
Leave your opinion in the comments and don’t miss the demo.
