Our verdict on Comet
Comet is a Chromium-based web browser from Perplexity AI, Inc. It combines conventional browsing with Perplexity AI-powered search, natural-language browser commands, contextual questions about open pages, and page summarization. It is designed for people who want research and browsing assistance built into the browser rather than added through separate tools. Comet is available on macOS, Windows, iOS, and Android, with support for bookmarks, page translation, voice control, and Chrome Web Store extensions.
Its strongest distinction is the range of AI-assisted browsing features. Personal Search can use browsing history, while the Contextual Ask button provides a way to question open web pages. Gmail connectivity adds an email-focused workflow, and natural-language commands extend AI assistance beyond search. Built-in ad blocking, cross-device synchronization, and Chrome extension compatibility help keep the browser practical for everyday use. Synchronization covers bookmarks, passwords, autofill, themes, history, extensions, and open tabs across Comet devices.
The published plan structure is straightforward: Comet is free to download, and the Free plan lists browser access at no cost. Some Perplexity AI capabilities may vary by subscription plan, so users primarily choosing a browser for predictable AI access should review how those capabilities apply to their account. Comet is a strong fit for users who want AI search and page assistance across desktop and mobile. It is less suited to buyers seeking a broad set of verified third-party integrations beyond Gmail or a browser focused on conventional browsing with minimal AI involvement.
