Comet is Perplexity's bet that the browser itself should be the agent. It is free, it runs on every major platform, and since March 2026 it has the most direct admin controls of any agentic browser.
Key Takeaways
- The most complete agent browser. — Comet's assistant fills forms, compares products and runs multi-step tasks, on macOS, Windows, Android and iOS.
- Free to start. — The browser is free. Perplexity Pro ($20/mo) and Max ($200/mo) raise limits; Enterprise Pro is about $40 per seat per month.
- Enterprise controls that matter. — Comet Enterprise installs silently through MDM and lets admins allow answers only, or actions only on approved domains.
What Comet does
Comet is a Chromium-based browser with Perplexity's assistant built in. You ask in plain language, and the assistant reads pages, fills forms, compares products and works through multi-step tasks such as bookings and email. It shipped on desktop in July 2025, became free for everyone that autumn, and reached Android in November 2025 and iOS in March 2026 (nohacks.co).
Its security history is part of any review. In August 2025 Brave published an indirect prompt-injection chain: hidden text in a Reddit comment made Comet read the user's email address, trigger a one-time password and pull the code from Gmail. Perplexity patched it; Brave's retests found the first fix incomplete. The lesson applies to every agent browser, but ask Perplexity what changed.
Scorecard: 18/20
| Criterion | Score | Why |
|---|---|---|
| Agent | 5/5 | Multi-step tasks across sites, including bookings and email. |
| Control | 5/5 | MDM install; actions off or limited to approved domains in Comet Enterprise. |
| Safety | 3/5 | Patched after Brave's 2025 disclosure; fewer published details on defenses than Google or Anthropic. |
| Reach | 5/5 | Free, worldwide, desktop and mobile. |
Pricing and Comet Enterprise
The browser is free. Perplexity Pro (about $20 a month) and Max (about $200 a month) raise usage limits and include Comet Plus; Enterprise Pro is about $40 per seat a month (Carly, July 2026). Comet Enterprise adds a silent installer for MDM rollouts and a policy to allow answers without actions, or actions only on approved domains.
Who it fits, and who should look elsewhere
- Fits: teams that want a dedicated agent browser on desktop and mobile, with a central policy for where the agent may act.
- Look elsewhere: if you will not roll out and support a second browser (Gemini in Chrome and Claude in Chrome live inside Chrome), or if you only need summaries and drafting (Dia or Edge carry less risk).
Perplexity Comet alternatives
- Gemini in Chrome: no new browser, strict human checkpoints, US only.
- Claude in Chrome: Anthropic's extension with a safety classifier and site lists.

Is Perplexity Comet free?
Yes. The Comet browser is free to download and use. Perplexity Pro at about $20 a month and Max at about $200 a month add higher limits and Comet Plus, Perplexity's publisher content bundle. Business teams buy Enterprise Pro at about $40 per seat a month.
Is Comet safe to use?
In August 2025 Brave showed that hidden text in a Reddit comment could make Comet take over a user's Perplexity account. Perplexity shipped fixes, though Brave's retests found the first fix incomplete. For company use, deploy Comet Enterprise and limit agent actions to approved domains, or allow answers without actions.
What platforms does Comet run on?
macOS and Windows since July 2025, Android since November 2025, and iOS since March 2026.
