Perplexity Comet
Free AI-native browser with a multi-model assistant in every tab
Best for
Perplexity Comet is an AI-native web browser from Perplexity that embeds a multi-model assistant directly into every tab and lets it act on web pages, rather than only describe them. Launched at $200/mo in mid-2025, Comet went fully free across iOS, Android, macOS, and Windows in 2026, which positions it as the first agentic browser available to general consumers without a paywall.
What Perplexity Comet does:
- •Multi-model assistant in every tab pick between Claude Opus 4.6, GPT-5.4, and Gemini 3.1 Pro inside the same chat panel, or let Comet route automatically based on the task type.
- •Agentic actions on live pages ask Comet to fill a form, complete a booking, summarise a thread, or compare three SaaS pricing pages side-by-side, and it operates the page on your behalf.
- •Cross-tab summarisation highlight 5-10 open tabs and Comet produces a one-screen synthesis with citations that link back to the source tabs.
- •Voice chat with web context talk to the assistant out loud while browsing, hands-free; useful while driving, cooking, or researching with notes.
- •Built-in ad and tracker blocker ships with native ad and third-party tracker blocking enabled by default, no extension required.
- •Finance Hub a dedicated panel that pulls live tickers, earnings calls, and analyst notes into a single workspace tied to your watchlist.
- •Model Council on Max plan runs the same query in parallel through Claude Opus 4.6, GPT-5.4, and Gemini 3.1 Pro and shows the three answers side-by-side for high-stakes research.
- •Native mobile apps iOS and Android versions ship with the same agentic actions, voice chat, and cross-tab summarisation as the desktop build.
- •Comet Plus publisher add-on a $5/mo upgrade that unlocks premium content from partner publishers (FT, WSJ-style sources) inside Comet's AI answers.
- •Privacy-first defaults ad blocker, tracker blocker, and an option to keep browsing history local rather than synced through Perplexity's servers.
Pricing:
- •Free $0/mo: full Comet browser, multi-model assistant, agentic actions, ad/tracker blocker, voice chat, mobile apps. No card required.
- •Comet Plus $5/mo: premium publisher content unlocked inside AI answers (financial press, premium news). Stacks on top of the free browser.
- •Perplexity Max from $200/mo: Model Council (parallel multi-LLM answers), priority access during peak load, larger context windows for long research sessions.
Limitations:
- •Not yet a Chrome replacement for power users extension support is narrower than Chrome and a few enterprise SSO flows still require a fallback browser.
- •Agentic actions can drift Comet sometimes mis-clicks on dense pages or stalls inside multi-step booking flows; watch it on anything financial or irreversible.
- •Privacy posture is still evolving AI features that operate on your tabs send page content to Perplexity infrastructure, so security-strict teams should review the data-handling policy before company-wide rollout.
- •Linux is not officially supported only macOS, Windows, iOS, and Android ship as first-party builds in 2026; Linux users still need Chrome or Arc.
Our Verdict
Perplexity Comet scores 7.9/10 because it is the first AI-native browser that genuinely feels like a browser (fast, multi-tab, native ad blocker) while letting an assistant act on pages rather than just describe them. Going fully free in 2026 made it the most accessible agentic browser on the market and a credible daily driver for anyone already living inside Perplexity for search.
For the Basic User, the value is that the AI is simply there: voice chat, summaries, form-filling, and a built-in ad blocker without installing extensions or learning shortcuts. The mobile apps in particular are friendlier than juggling ChatGPT plus a separate browser; one app handles search, the agent, and the page itself.
For the Vibe Builder, Comet is the cheapest way to experiment with agentic browsing. Open three competitor pricing pages, ask Comet to build a comparison table, and paste the output into a Notion doc; that is a five-minute task that used to take thirty. Pair it with a $5/mo Comet Plus subscription and you also pull premium publisher coverage into the AI answers, which is a meaningful upgrade for market or investment research.
Skip it if you live inside the Chrome extension ecosystem or need a battle-tested enterprise browser; in those cases, consider Chrome with a ChatGPT extension or try Dia Browser, both of which lean less heavily on a single AI vendor. Choose Comet when agentic actions and a multi-model assistant matter more than extension breadth.

Frequently Asked Questions
How much does Perplexity Comet cost in 2026?
Perplexity Comet is free across iOS, Android, macOS, and Windows. The optional Comet Plus add-on is $5/month and unlocks premium publisher content inside AI answers. Perplexity Max at $200/month adds Model Council (parallel multi-LLM answers) and priority access for heavy research workloads.
Perplexity Comet vs ChatGPT Atlas: which agentic browser is better?
Perplexity Comet ships native multi-model routing across Claude, GPT, and Gemini in every tab, plus a free tier across all platforms. ChatGPT Atlas integrates more deeply with OpenAI tools and memory. Choose Comet when you want multi-LLM optionality and zero cost; choose Atlas when your team is already standardised on the OpenAI stack.
Does Perplexity Comet replace Chrome for daily browsing?
For most users it can. Comet is built on Chromium, supports tabs and bookmarks the same way, and ships with a native ad blocker. Power users still hit gaps with niche extensions and the occasional enterprise SSO flow, so many keep Chrome installed as a fallback while making Comet the default.
What can Perplexity Comet's agentic actions actually do on a webpage?
Perplexity Comet can fill forms, summarise long articles, compare data across multiple open tabs, draft replies inside Gmail, complete shopping checkouts, and book reservations or appointments. It works best on common consumer flows; complex financial or legal pages still need human supervision because the agent can mis-click or stall mid-flow.
Is Perplexity Comet safe to use for work and sensitive browsing?
Comet ships with a built-in ad blocker, tracker blocker, and the option to keep history local. AI features that read your tabs do send page content to Perplexity infrastructure, so any security-strict team should review the data-handling policy before rolling out Comet across the organisation in 2026.
