Automates web tasks with an AI assistant in a Chromium-based browser

Comet by Perplexity is an AI-integrated web browser based on Chromium that uses Perplexity’s search engine by default and includes the Comet Assistant for task automation. The browser processes user queries through AI models to deliver summarized results with source citations, supporting features like tab management, email summarization, and webpage navigation. It operates on Mac and Windows platforms, with plans for broader availability, and requires an invite for initial access tied to Perplexity subscriptions.

Key functionalities include the sidebar chat interface for natural language prompts, voice mode for hands-free interaction, and agentic controls that allow the AI to perform actions such as accepting invitations or extracting data from filings. Technical implementation involves real-time web access for current information, integration with Chrome extensions, and profile customization with themes. Compared to Arc Browser, Comet provides deeper automation for multi-step tasks, while Arc focuses on visual tab organization; both use Chromium but differ in AI depth, with Comet’s premium tiers offering unlimited usage versus Arc’s free core features.

User reports indicate effective performance in research scenarios, such as generating reports from social sentiment or SEC documents, but note occasional delays in complex operations and rendering issues during full-screen use. Privacy features include data controls, though browser activity informs AI personalization. Against SigmaOS, Comet excels in agent-driven actions like form filling, while SigmaOS prioritizes workspace efficiency; pricing for Comet aligns with Perplexity’s free basic access and paid upgrades, generally lower entry than SigmaOS subscriptions.

Installation imports data from existing browsers and supports extension compatibility. The assistant handles specific commands, such as “take control of my browser” for guided sessions, and upcoming updates will add local file and desktop app management. Limitations include invite-only rollout and potential stalls on secure sites.

At the end, we suggest you test prompts in controlled environments before full adoption to verify compatibility with personal workflows.
