Our verdict

Comet suits existing Perplexity users who want an assistant that summarizes, searches and handles some tasks inside the browser. The trade-offs are that the agent needs a paid plan from $20/month, the code is closed, and public security research shows prompt-injection risk has not been fully resolved.

Best for: Perplexity users who want search and page Q&A inside the browser

Skip it if: Anyone who prioritizes maximum privacy or needs open-source software

Pros

  • Free download with Windows, macOS, Android and iOS versions
  • Chromium-based, can import bookmarks and history and runs most Chrome extensions
  • Ask and Summarize buttons for the open page, a Gmail connector and a built-in ad blocker

Cons

  • The agent assistant is not on the Free plan, and Pro/Max limits have no published figure
  • Brave and LayerX published prompt-injection attacks; Brave said Perplexity had not fully mitigated its finding, and Perplexity classified LayerX's as having no security impact
All pros and cons · Who is it for?

Skip it if

  • Anyone who wants the agent assistant without paying

Problems it solves

Experience & key features

What Comet is

Comet is a browser from Perplexity AI, described on its site as "the AI browser that acts as a personal assistant." According to Wikipedia, the Windows and macOS versions came out on 9 July 2025, Android on 20 November 2025 and iOS on 18 March 2026. The help center says Comet is Chromium-based, can import data from other browsers and supports most Chrome extensions.

Key features

The assistant sits beside the page: an Ask button for questions about the open page, Summarize, natural-language commands for tab management and a Gmail connector for email and calendar queries. The product page shows examples such as comparing how outlets cover a story, drafting an email reply or finding a product to buy. The Android app adds voice mode and cross-tab summaries, per its Google Play description.

Pricing and limits

Comet opened to all users in early October 2025 after an initial period limited to Max subscribers. The browser is a free download, but the help center states that the Free plan does not include Comet Assistant. Using the assistant takes at least Pro, at $20/month or $17/month billed yearly; Max costs $200/month or $2,000/year. Both list only "monthly limits" with no figure. Verified students and educators can get Education Pro for $10/month. For businesses, Enterprise Pro starts at $40/seat/month with 80 assistant queries a month, and Enterprise Max includes 800.

Security and disputes

In August 2025, Brave researchers reported that Comet fed web page content to its model without separating it from the user's instructions, so hidden text on a page could drive the assistant's actions. Brave said the flaw appeared patched on 13 August 2025 but later found Perplexity had not fully mitigated it. In October 2025 LayerX described CometJacking, in which a malicious link could make the assistant pull data from connected email and calendar and send it out; Perplexity classified the finding as having no security impact. On the legal side, Decrypt reported on 5 August 2026 that the US Ninth Circuit Court of Appeals overturned the preliminary injunction that had blocked Perplexity's shopping tools on Amazon; the underlying lawsuit continues.

Compared with other browsers

Compared with Chrome or Edge, Comet puts the AI assistant at the center but is closed source and gates the agent behind paid plans. Readers who want an agentic AI browser can also look at Opera Neon, and those who put privacy first should compare Brave.

Privacy

Perplexity's privacy notice (last updated 23 October 2026) says that, depending on settings, it records browsing history and usage for Comet users with a synced account. Browsing data, site permissions and download records are stored locally; the notice says Perplexity does not access this data, though it may still be used to provide and improve Comet. The notice lists improving or creating services, including AI models, as a use of data, while email content handled by Email Assistant is not used to train models. The help center says passwords and payment details are stored locally with encryption. On security, Brave disclosed an indirect prompt-injection flaw in August 2025; Perplexity patched it, but Brave later said the vendor had not fully mitigated this class of attack. In October 2025 LayerX disclosed a malicious-link attack it called CometJacking, which Perplexity classified as having "no security impact," according to The Hacker News. Comet is closed source, so outsiders cannot easily verify the fixes.

Scores

Ease of use
7.0
Why this score

Familiar thanks to Chromium and with import tools from other browsers, though some Google Play reviews describe a clunky login and frequent bot checks. The interface is English-only.

Features
7.8
Why this score

Multi-tab assistant, summaries, a Gmail connector, ad blocking and Chrome extensions; the agent is the differentiator over standard browsers but needs a paid plan.

Value for money
6.8
Why this score

The browser is free, but its headline feature sits behind Pro at $20/month ($17/month billed yearly) with unpublished limits; Max costs $200/month.

Performance
6.5
Why this score

No independent benchmark was found to cite. The score rests on the Chromium base and stability complaints in Google Play reviews.

Support
6.5
Why this score

A dedicated help center and support channels for paid plans, though one Google Play review says in-app feedback was hard to reach.

Privacy & security
5.2
Why this score

Browsing history is recorded depending on settings, the code is closed, data may be used to improve AI models, and two published prompt-injection findings lack confirmed full mitigation.
