Comet by Perplexity
Comet is Perplexity's AI browser for research, agents, and automation across Mac, Windows, iOS, and Android.
Comet's real argument is that the assistant lives in the browser, not next to it — and now that it covers Mac, Windows, iOS, and Android, the old portability objection is gone. For anyone already on a Perplexity paid plan, it's a low-friction way to turn everyday tab clutter into delegated tasks. If you want a neutral browser you never think about, it's more machinery than you need.

Skip Comet if you need offline or mobile browsing, casual light browsing, strict data privacy, or you can't accept the 50-query daily cap on the free tier.
The free tier caps at 50 AI queries per day, so heavy users will quickly hit the limit and need to upgrade.
Comet's freemium model gives casual users a free tier with 50 queries/day, but heavy researchers will need the $20/mo Pro for unlimited queries. Compared to alternatives like Perplexity's own subscription or general AI browsers, Comet is competitively priced for deep research, though free alternatives like Bing AI or Brave Search might suffice for lighter use.

About Comet by Perplexity
Comet by Perplexity is an AI browser that puts an assistant inside every tab instead of in a separate sidebar app. Perplexity sells it as a browser that "works for you" — you ask things like "how are different news outlets covering this differently?" and it reads across sources for you, or you hand off tasks such as drafting a reply with your upcoming schedule, building a basic website, mapping a study plan from a syllabus, or buying an office chair. It is aimed at people whose day involves a lot of open tabs: researchers, journalists, analysts, students, and product folks who digest material faster than they can read it. The pitch breaks into four buckets that Perplexity names outright: AI that understands, AI that builds, AI that emails, and AI that shops (plus AI that creates). Under the hood those map to the familiar Perplexity assistant pattern — conversational queries, multi-source synthesis, and task delegation — and Perplexity maintains a Comet Resource Hub and a "ways to use Comet" library for learning what can be delegated, from inbox wrangling to grocery ordering to vacation planning. The distribution story has changed since this profile was last written. Comet now ships as a downloadable browser for Mac, Windows, iOS, and Android, so the old "web app only, no mobile app" caveat no longer holds. Perplexity also publishes FAQ answers on installation, which search engine Comet uses, making it your default browser, controlling privacy settings, and safe browsing. Positioning: Comet competes with Chrome, Arc, and Edge's Copilot side panel for attention, but its differentiator is that agentic task delegation sits in the browser itself rather than bolted on. If you already pay for Perplexity Pro, Comet is the natural place to spend those queries; if you want a plain, low-overhead Chromium browser with no assistant hooks, it is more surface area than you asked for.
Behind the Verdict
We'd pick Comet when the bottleneck in your day is reading and coordinating rather than typing. The demos Perplexity shows — comparing how outlets frame one story, drafting a reply that pulls your schedule, turning a syllabus into a week of study — are the right shape of work for it. If your job is tabs, sources, and small errands, the assistant-in-the-browser model earns its place. Where it bites: delegation is only as good as the access you give it. Tasks like emailing, booking, or shopping touch accounts you may not want an agent inside, and Perplexity's own FAQ points you at privacy controls and safe-browsing settings for a reason. Decide your comfort line before you hand over an inbox. Compare it to Copilot in Edge, which is the closest mainstream equivalent. Edge's advantage is that it's already on your machine and costs nothing extra; Comet's advantage is that Perplexity's research-and-cite behavior is the default, not a sidebar you have to open. Against Arc, Comet is less about rethinking browser UI and more about putting an agent at the center. Switching cost is real, not theoretical. Your bookmarks, extensions, and password manager all have to move, and Comet's FAQ exists partly because that's fiddly. Perplexity answers the plumbing questions — default browser, install, which search engine powers it — but budget an afternoon. If you're already paying for Perplexity, try Comet as a second browser for research sessions before you commit to it as your daily driver. That gives you the delegation upside without betting your whole workflow on a young browser. Pass on Comet if you need a browser that stays out of the way, or if your work is governed by policies that don't allow assistant tools touching mail and purchases. Also pass if you're happy with your
