Perplexity Comet
Also known as: Perplexity Comet, Comet, Comet Browser, Perplexity
AI native, agentic web browser from Perplexity, built on Chromium, where an assistant lives natively in the sidebar, knows which tab you are on, retains context across your session and tabs, and takes actions on your behalf like booking a flight, filling a form, comparing prices across tabs, or running Deep Research.
Perplexity Comet is an AI native, agentic web browser built by Perplexity, the company behind the citation first answer engine. It is Chromium based, so it imports Chrome bookmarks, history, passwords, and extensions and runs Chrome Web Store extensions, but instead of AI bolted on as an add on, an assistant lives natively in a sidebar on every tab. It knows which page you are on, retains context across your session and across open tabs, and can take action: draft an email reply, fill a form, compare prices across three tabs, summarize what you just read and cross reference it against yesterday, or research a trip and assemble a report across the pages you visit rather than handing you links.
Comet launched in July 2025 as a two hundred dollar per month Max only desktop product, went free worldwide around October 2025, and reached Android and then iOS by March 2026, so it is now free on macOS, Windows, Android, and iOS with no account required for core features, though not on Linux. It is multi model: Max subscribers pick from Perplexity's Sonar, Claude Opus 4.6 as the default, Claude Sonnet, GPT 5.4, Gemini 3.1 Pro, and Kimi K2.5, and a Model Council feature runs three frontier models in parallel and synthesizes them. It also ships cross tab synthesis, voice mode, a built in ad and tracker blocker, a Finance Hub, slash command shortcuts like cite, tldr, and fact check, and Max only Background Assistants that run autonomous tasks on a schedule. Perplexity raised about two hundred million dollars in June 2026 at a roughly twenty billion dollar valuation, positioning the free browser as the front door of the agent economy.
Comet fits researchers, writers, analysts, and knowledge workers who live in the browser and want it to act rather than just display. It is a weaker fit for Linux users, for casual browsers who will not use the agent, and notably for anyone with strict security or privacy requirements, given documented prompt injection and phishing vulnerabilities and an ad profiling data model that reviewers have flagged.

Use cases & customers
Primary use cases

Deployment options
Integrations
A Chromium browser that imports Chrome bookmarks, history, passwords, and extensions and runs Chrome Web Store extensions, with an assistant that acts across tabs, web apps, email, shopping, and forms. Slash commands trigger built in tasks, and Perplexity's separate API Platform offers Agent, Search, Sandbox, and Sonar APIs for developers who want the underlying capabilities programmatically.
In practice
A user types compare the pricing of the top three project management tools into the sidebar. Comet opens tabs, reads each page, and returns a synthesized comparison with citations.
An analyst has ten research tabs open and asks Comet to summarize findings across all of them, surface common themes, and flag contradictions, something a sandboxed extension cannot do.
A Max user sets a Background Assistant to summarize the morning's emails and the day's meetings at 8:30 AM daily, running hands free on a schedule.

Pricing
Free to download and use; Pro at twenty dollars per month, Max at two hundred dollars per month
free browser; capability gated by flat Perplexity subscription tiers plus a small publisher add on
What is public
Nearly everything: the browser is free, and Pro at twenty dollars, Max at two hundred dollars, Comet Plus at five dollars, and Enterprise per seat prices are all published.
Billing mechanics
The browser is free. Capability scales through flat monthly or annual Perplexity subscriptions, Pro and Max, with a five dollar Comet Plus publisher add on that is included in paid plans, and per seat Enterprise Pro and Enterprise Max tiers around forty and three hundred twenty five dollars.
Cost watchouts
The full model selection, Model Council, and Background Assistants sit behind the two hundred dollar per month Max tier, and premium publisher content in answers is a separate five dollar per month Comet Plus add on unless you are on Pro or Max.
Variable cost rationale
Comet is a free browser and its paid tiers are flat monthly or annual subscriptions, so there is little usage based cost exposure for the browser itself; only the Max tier carries a monthly credit pool for the separate Labs and Computer features.
Additional watchouts
Free is generous but uses lighter models; the differentiating agent depth, model choice, and Background Assistants require Max at two hundred dollars per month, a ten times jump from Pro.
Sales call required
No — self-serve available
Free / trial
The browser is free on macOS, Windows, Android, and iOS with no account required for core agentic features
Lowest paid plan
Perplexity Pro at twenty dollars per month, roughly sixteen dollars sixty seven per month billed annually
Key ambiguities
How much of the agentic value a given user gets on the free tier versus needing Pro or Max, since free users get lighter models and reduced automation depth.
Missing data
Exact enterprise contract terms beyond the published per seat headline prices.
