Perplexity Comet
The AI research browser — free on Mac, Windows and Android
Overview
Comet is Perplexity's AI browser: every tab gets an assistant that reads, summarizes and cross-references pages, and an agent mode handles multi-step browsing tasks. Free since October 2025 (with rate limits), on macOS, Windows and Android — the most accessible way to feel agentic browsing.
Features
How to Get Started
Download from comet.perplexity.ai, import your Chrome profile, and browse. The sidebar assistant works on any page; agentic tasks are rate-limited on the free plan and expanded with Perplexity Pro.

Is Comet free?
Yes — the browser is free including agentic browsing, but with rate limits. Power users upgrade to Perplexity Pro for higher throughput.
Comet vs ChatGPT Atlas?
Comet is research-first (multi-source synthesis with citations) and runs on Windows; Atlas is workflow-first and was still macOS-only in early 2026 before merging into the ChatGPT desktop superapp.
Does it replace Chrome?
It's Chromium-based, so your extensions, passwords and habits carry over — most users switch fully within days.
