Comet

Comet is a new AI-native desktop browser built by Perplexity that turns every tab into an intelligent workspace. It fuses live web search, large-language-model reasoning, and agentic actions so you can research, summarize, generate content, and complete multi-step tasks without ever leaving the address bar.

Key Features and Highlights

1. Built-in Perplexity Search: Ask questions in the address bar and get real-time, cited answers from the web while you browse.
2. Command Bar Actions: Type “/” to summon 100+ ready-made agents that write emails, compare products, summarize PDFs, or run full workflows in seconds.
3. Side-by-Side AI Workspace: Open a collapsible sidebar where the same context-aware AI can chat, cite sources, and continue threads across every site you visit.
4. Context-Aware Autofill: Automatically draft forms, tickets, or posts using live page context—no copy-paste required.
5. Privacy-First Architecture: Search queries are anonymized, cookies and trackers are blocked by default, and all chat history stays local until you choose to share it.
6. Cross-Device Sync: History, collections, and AI threads sync instantly across macOS, Windows, and mobile Perplexity apps.
7. Zero-Cost Entry: Free to download and use core features; Pro subscribers unlock higher usage limits and advanced models.
