Comet Browser by Perplexity

Comet is an AI-native web browser built by Perplexity on the Chromium engine, so it supports existing web extensions and sites. Its defining feature is an AI assistant embedded in every tab that can summarize pages, draft email replies, organize open tabs by project, and carry out multi-step tasks, such as researching a topic or helping with online shopping, based on natural-language instructions rather than manual clicking through pages. Perplexity first released Comet in July 2025 on Windows and macOS, initially limited to subscribers of its $200-per-month Perplexity Max plan, before making it free and available worldwide in October 2025. Mobile versions followed, with an Android release in November 2025 and an iOS release in March 2026. Because it is built on Chromium, Comet is compatible with most existing browser extensions and websites, while adding Perplexity's AI search and assistant capabilities directly into the browsing experience. Comet is aimed at users who already rely on Perplexity's AI search and want that assistant woven into everyday browsing rather than kept in a separate app or tab. As a newer entrant, it competes directly with other AI-forward browsers, and some early reviews note its AI integration still has room for improvement compared with a fully mature browser.
