Perplexity Comet

The AI browser that researches, summarizes, and acts — all while you browse.

Perplexity Comet is a free AI-native web browser that embeds a powerful research assistant directly into every page you visit. Built by Perplexity AI — the company processing over a billion search queries per month — Comet replaces the exhausting cycle of switching between tabs, search engines, and AI tools. It is the first browser where the AI is not a plugin bolted on top, but the engine underneath.

Perplexity Comet is an AI-native web browser built by Perplexity AI that embeds a multi-model assistant directly into every page you visit. Unlike traditional browsers where AI comes as clunky add-ons, Comet’s assistant is integrated into every action — the agentic model means Comet will not only suggest links, but will also take actions, navigate, summarize, collate data, and complete user-initiated tasks across tabs, apps, and web workflows. The browser launched in July 2025 as a $200/month desktop product, but Perplexity dropped the paywall on March 18, 2026 and rolled it out free on iOS, Android, Windows and Mac.

Perplexity Comet vs Competitors

Comet vs Google Chrome Chrome is still the gold standard for developers and anyone who lives in DevTools — its extension ecosystem, developer tooling, and raw performance remain unmatched for technical users. Comet is not yet a replacement for Chrome for everyone — it is the right choice for the kind of person who reads a lot, writes a lot, and treats the browser as a workspace rather than a tab graveyard. If you primarily browse for content consumption and research, Comet is a genuine upgrade. If you are a developer who needs DevTools constantly, keep Chrome alongside it. Futurepedia

Comet vs Arc Browser Arc reimagined the browser interface with spaces, splits, and a cleaner tab system — it is a design-forward browser for people who want better organisation. Comet takes a different approach entirely, prioritising AI capability over interface design. Arc does not have a built-in AI research assistant that reads your pages and automates tasks; Comet does. If your primary frustration is messy tabs, Arc wins. If your primary frustration is wasting time on manual research and repetitive browsing tasks, Comet wins.

How to Get Started with Perplexity Comet

  1. Visit perplexity.ai/comet and click Download — choose your platform (macOS, Windows, iOS, or Android). The download is free and requires no credit card.
  2. Sign in with your existing Perplexity account or create a free one with your email or Google account. Your search history and preferences sync across all devices automatically.
  3. Install your existing Chrome extensions from the Chrome Web Store — Comet supports them natively. This takes under five minutes and means your workflow tools like Grammarly and 1Password work immediately.
  4. Open any webpage and click the Assistant icon in the top right corner. Ask it to summarise the page or answer a question about what you are reading — this is the fastest way to feel the core value immediately.
  5. Try one agentic task: type something like “compare the pricing of the top 3 project management tools” into the sidebar. Watch Comet open tabs, read each page, and return a comparison. This is where the browser genuinely earns its place in your workflow.

Download it, use it for three days on your normal workflow, and you will know immediately whether it fits. Start free at perplexity.ai/comet.

Context-Aware AI Sidebar You can open the AI assistant by clicking the Assistant icon in the top right corner of the browser — once you start typing, it becomes an interactive space for real-time chatting where you can ask it to find specific information or toss out general prompts for suggestions. The sidebar always knows which tab you are on, meaning you never have to copy-paste content into a separate AI tool again. It reads the page for you and answers questions about it in real time.

One-Click Page Summarisation Page summarisation is one of Comet’s best features — a quick click on the three horizontal lines instantly prompts the assistant to generate a short summary of the webpage you are currently viewing. For researchers and analysts who read dozens of articles per day, this feature alone saves hours of reading time each week by surfacing the key points in seconds. Vezadigital

Agentic Task Automation You type a task into the sidebar — such as “compare the cheapest MacBook Air M3 prices across Amazon, Best Buy, and B&H Photo” — and Comet opens tabs, navigates each site, pulls the prices, and shows a comparison table in the sidebar. Comet can run agentic flows for comparing flight prices across three sites, filling out a slow form on a vendor portal, and pulling product specs from competitor pages into a comparison table.

Deep Research Integration Deep Research now generates deliverables directly — PowerPoint presentations, spreadsheets, dashboards, and websites from your research prompts — with no more copy-pasting findings into other tools. This makes Comet the only browser where you can go from question to finished research document without ever leaving the browser window. Justwords

Chrome Extension Compatibility Comet runs on the Chromium engine, so you can use Chrome extensions with it. Extensions including uBlock Origin, 1Password, Bitwarden, React DevTools, Grammarly, Dark Reader, and Vimium all install directly from the Chrome Web Store within Comet. You get a genuinely new browser experience without sacrificing any of your existing tools and workflow extensions. Search Scale AIFuturepedia
