Perplexity Comet: We Replaced Chrome for Two Weeks

An AI browser that summarizes your research at 11 PM—but it knows everything you read.

It was 11 PM and we had forty-three tabs open—three research windows, two comparison tools, a shopping tab pile, and the browser crying for mercy. We clicked the Comet button. Thirty seconds later: a summary of our entire research thread, organized by topic, with suggested next steps. No copy-paste. No manual scrolling. Just: “Here’s what you learned.” That’s the magic moment. Then we saw the privacy policy and realized Perplexity was building an ad-targeting profile from every single page we’d visited. Magic and surveillance sitting in the same address bar.

We spent two weeks making Comet our primary browser. Here’s what actually happened.

What Perplexity Comet Actually Is

Perplexity Comet is a Chromium-based browser with an AI assistant built directly into the navigation experience. It launched in mid-2025 as a $200-per-month exclusive for Max subscribers, but in October 2025 Perplexity made it free for everyone. In March 2026, the company expanded it to iOS with the full assistant feature set.

The free version gives you autonomous tab summarization and voice search. If you pay for Comet Plus ($5/month), you get access to premium publisher content baked into answers. Max subscribers ($200/month) unlock a “background assistant”—a separate agent running in the background that can handle multi-step tasks like adding concert tickets to your calendar or processing receipts while you’re doing something else.

The core pitch isn’t “replace Chrome”; it’s “let the browser do the boring research work while you focus on decision-making.”

What Actually Works

The tab summarization is legitimately useful. We ran it on everything: 30-tab research sessions on renewable energy equipment, comparison-shopping for project management tools, and a typical rabbit hole of SaaS pricing pages. Every time, the summary was coherent and picked out the actual decision drivers instead of rewriting the URLs.

The agent comparison feature saved us time on three separate buying decisions. We’d open five competitor pricing pages, ask “show me how these compare on price, features, and trial length,” and the assistant would generate a table without us manually building it. That’s not Chrome doing that. That’s real leverage.

Calendar and email integration on Max is solid—we tested adding meeting times and flight confirmations by giving the agent a screenshot. Success rate was probably 85%, which is genuinely high for agentic work.

Voice mode worked consistently for quick queries (“what’s the current price of Jackery 1500” while we were packing).

What Breaks

Agentic failures spike on complex sites. According to Tools Stack AI, shopping automation fails on unusual payment flows and dynamic forms—exactly what you’d hit on a custom checkout or a vendor with weird login steps. We had two shopping tasks fail outright and one succeed after the agent misclicked twice. The agent could see the page, understood what it needed to do, and still got stuck on a form field that required manual activation.

Memory usage climbing is real. With 30+ tabs, Comet got noticeably slower than Chrome on the same hardware. We didn’t see CPU doubling, but the slowdown was noticeable enough that we’d close tabs more aggressively than we do in Chrome. After a week of this, we stopped running as many background research tabs.

Crashes: two in 14 days, both during multi-tab agentic work. Recoverable, but annoying when you’re mid-workflow. Both times the assistant was running summary jobs across 20+ open pages.

The Privacy Trade-Off Nobody’s Discussing

Here’s the thing we can’t gloss over: Perplexity collects your browsing and search history from Comet to build ad-targeting profiles. Not anonymized browsing. Your actual history. Used for serving ads.

This is the tension at the core of Comet. You get a powerful assistant because Perplexity is essentially reading over your shoulder at every site you visit. The assistant needs access to your pages to help with summarization and task completion. That same access trains the ad profile.

Chrome does this too, but at least you know you’re the product. With Comet, you’re getting an active assistant while simultaneously opting into more granular tracking than most browsers. It’s an honest tradeoff, but it’s worth naming.

Comet Plus adds publisher content for $5/month and directs 80% of revenue to publishers—which is a different monetization angle than Chrome. Doesn’t change the data collection, though.

The Comparison Problem

If you already pay for Perplexity Pro at $20/month or Max at $200/month, does Comet add enough to justify switching your entire browser? We’d argue no—not yet. The tab summarization is the killer feature, but a Pro or Max subscriber already has web search, research, and agent capabilities in the Perplexity app. Comet doesn’t give you much you couldn’t do by opening the app in a separate window.

For people using Chrome + a separate Perplexity tab, Comet saves window-switching. That’s real but small.

For research-heavy power users comparing multiple tool stacks, the honest question is: do you want your entire browsing history tied to one company’s ad network, even if the assistant is helpful? That’s a personal risk tolerance call, not a feature call.

Who Should Actually Use This

If you’re on Max and you care about task automation—concert tickets, flight bookmarks, calendar integration—the background assistant is worth the install. You already pay for Max; Comet gives you a reason to use it.

If you’re a heavy researcher or analyst doing constant tab-switching and manual comparison work, the free Comet is worth a two-week trial. The summarization alone might change how you work. Just know what you’re trading for it.

General Chrome users? Not yet. The stability isn’t there, the memory footprint is higher, and unless you love the assistant angle, you’re replacing a rock-solid browser with a beta product.

The Honest Call

We’d keep Comet installed as a second browser, not a primary. The summarization is genuinely useful, and there were days we actually reached for it before Chrome for research work. But two crashes in two weeks, memory overhead, and the looming question of “how’s my browsing data being used” kept us from fully committing.

The product works. It’s faster than it has any right to be at this stage. The assistant is competent on straightforward tasks. But “works” and “ready to replace your primary browser” are different things. Comet is the former and getting close to the latter.

If you’re already in the Perplexity ecosystem on Max, install it and run the background assistant. If you’re a free user, try it for a week. Just don’t uninstall Chrome yet.
