New AI browsers: 8 agentic browsers to watch in 2026

Comet is Perplexity's browser, and it's the name every comparison of new AI browsers starts with. Perplexity released it to everyone for free, and it now runs on Mac, Windows, iOS and Android. It's built on Chromium, so most Chrome extensions work, and the import step brings over your bookmarks, history and passwords. Passwords, payment details and sign-in tokens are kept locally on your device, encrypted.

What's new is the Comet Assistant, an agent that reads the page you're on, works across your tabs and clicks through a task for you while you watch. Here is the catch most guides skip: the browser is free, the agent is not. Perplexity's plan table lists Browser Agent queries as "No" on the free plan, with monthly limits on Pro and Education Pro. The free plan also caps Pro Searches at 3 a day.

The discounted way in is Education Pro, at $10 a month for verified students and educators. For a team, Enterprise Pro costs $40 a month or $400 a year per seat and sets the agent at 80 queries a month: about $0.50 a query if you use them all. Enterprise Max raises that to 800 a month. For Perplexity itself, see our Perplexity alternatives and our Perplexity training guide.

Who it's for: anyone who wants to try an AI browser without paying, and a researcher who already lives in Perplexity. Skip it if you want the agent and plan to stay on the free plan.

The risk: an agent that clicks for you can also click wrong. Watch the first tasks live, and keep logins to your bank and work tools out of its reach until you trust it.

Auto browse is Google's agent inside Chrome: you ask Gemini to do a task, and it opens pages, fills forms and moves through a site on its own. It's the newest name on this page that needs no new browser. Google's plans page lists it on Google AI Pro, and with the highest access on Ultra; the Chrome help center also lists Google AI Plus as enough to qualify.

The price ladder is short. Google AI Plus costs $4.99 a month, AI Pro $19.99 a month and AI Ultra starts at $99.99 a month. That makes Plus the cheapest monthly ticket to a mainstream browser agent on this page. But read the conditions before you subscribe: you must be 18 or over and in the US, run the latest Chrome with your device language set to English, and use a personal Google Account. It works on computers and, rolling out gradually, on Android phones and tablets, where India also qualifies; it isn't on iPhone or iPad, it doesn't run in Incognito, and it isn't available if you sign in to Chrome with a school account.

Gemini asks you to review before it sends a message, submits a web form or schedules an event, which is the right default. For the assistant itself, see our Gemini review and the Gemini alternatives.

Who it's for: a US Chrome user who wants an agent without moving bookmarks, extensions and passwords. Skip it if you live outside the US (or India, on Android) or browse in another language: the requirements rule you out.

The risk: Google calls auto browse experimental. Expect it to change scope and limits as it rolls out, and don't build a business process on it yet.

Dia comes from The Browser Company, the team behind Arc. Atlassian completed its purchase of the company in 2025, a deal of about $610 million in cash, with the stated aim of making Dia the AI browser for work, and the company ended active development of Arc to build it. Dia puts a chat next to your tabs: ask it to find, summarize, draft or build something from what you have open.

The pricing changed in 2026, and many guides still show the old numbers. Better Answers costs $10 a month and adds the Morning Brief and connected tools. Better Days costs $100 a month for 20x more asks. Usage is counted in Tasks, a unit of effort, so a simple request uses a fraction of one and a big report uses more. The monthly allowance resets each cycle and doesn't carry over. Extra usage comes in $20 blocks that stay valid up to three months, and unused credits aren't refunded if you cancel or downgrade.

The trap is the free plan. For new Mac users, Free is a clean, organized browser with no AI features at all. You get a 14-day trial of Better Days, no card needed, and then the AI stops unless you pay. Paid plans start with new Mac users; Dia says Windows stays as it is for now. If you run out mid-cycle, AI features pause rather than billing you overage.

Who it's for: a former Arc user, or a knowledge worker who wants a calm browser with an assistant that sees every tab. Skip it if you want AI for free on a Mac.

The risk: direction. Dia is now an Atlassian product aimed at work, and its pricing has already moved once. Use the trial to measure how many Tasks a normal week eats before you pick a plan.

Opera Neon is Opera's separate, agent-first browser. You can download it for free, and that free tier already does something unusual: it ships a Browser CLI and an MCP connector, so you can plug Claude, ChatGPT or your own agent into the browser instead of using Opera's. Free also includes an AI chat that summarizes pages and compares products, the built-in ad blocker and a free VPN.

The Standard plan, at $19.90 a month, turns on Neon's own agents that act on the web, plus deep research, image and video generation, code with deploy options, skill cards, scheduled tasks and long memory. It lists models from OpenAI, Anthropic and Google, including GPT-5.5, Opus and Gemini 3. The price includes applicable taxes and the subscription runs month to month, so there's no annual lock-in to weigh.

One line at checkout matters: you agree for Opera to start providing Neon immediately and acknowledge that you lose the right to withdraw from the contract. Treat the first month as non-refundable. Neon runs on Windows or macOS.

Who it's for: a power user who wants agents, research and generation in one subscription, or a developer who wants a browser their own agent can drive for free. Skip it if you're on Linux or a phone.

The risk: Opera runs Neon next to its main browser, which has its own free AI. Check which product a feature belongs to before you pay.

Fellou sells itself as an agentic browser: you describe a job, it plans the steps and runs them across sites, and you can schedule tasks to repeat. What makes it worth watching is that its pricing tells you roughly what a task costs, which few vendors on this page do.

Fellou counts usage in Sparks. New users get 1,000 Sparks as a bonus, which Fellou puts at about 4 tasks. Plus costs $19 a month for 2,000 Sparks a month, about 8 tasks, so roughly $2.38 a task. Pro costs $39.90 a month for 5,000 Sparks, about 20 tasks, or $2.00 a task. Billed annually, Plus drops to $192 a year ($16 a month) and Pro to $384 a year ($32 a month). Fellou advertises 20% off, which holds on Pro; on Plus it's 16%, $192 against $228 for twelve monthly payments. Ultra is $199.90 a month.

Scheduled tasks are capped by plan: 2 on Free, 3 on Plus, 5 on Pro. If your use case is a weekly report or a daily price check, count your schedules first.

Who it's for: a founder or marketer who wants a few real automations a week and likes to know the cost of each. Skip it if you'd run dozens of tasks a day: at around $2 a task, look at the workflow tools in our AI agent platforms ranking or our ranking of AI agents for volume.

The risk: "approximately" is doing a lot of work. A complex task can burn more Sparks than the average, so spend your free bonus on the task you actually plan to run.

Microsoft changed the AI in Microsoft Edge in 2026. It retired Copilot Mode, the separate AI mode it had launched in Edge, and folded its features into the regular Copilot in Edge. The agent part, once a limited preview called Copilot Actions, is now Browse with Copilot.

Browse with Copilot is on Edge desktop for Microsoft 365 Premium subscribers in the US only, with usage limits. Microsoft 365 Premium is listed at $199.99 a year, and Microsoft's page showed it at $139.99 a year, or $13.99 a month, in 2026. Journeys, which groups your past browsing into topics you can pick up again, is free on desktop in all English markets (en-US, en-GB, en-CA, en-AU, en-NZ, en-IN, en-SG); on mobile it's US only.

If you already pay for Microsoft 365 Premium for Word, Excel and Outlook, the browser agent is a bonus worth switching on. If you don't, compare that yearly price with a monthly agent subscription elsewhere on this page. For Microsoft's assistant on its own, see our Copilot alternatives.

Who it's for: a US household or freelancer already on Microsoft 365 Premium. Skip it if you're outside the US: the agent isn't offered there.

The risk: Microsoft has reshaped this feature twice in a year. Older guides still describe a free Copilot Mode with Actions; that's out of date.

Brave's assistant, Leo, is free to use and runs in Brave on macOS, Windows, Linux, Android and iOS. What's new is Leo's agentic browsing, which Brave opened for early testing in all release channels in 2026. You switch it on yourself with the "Brave's AI browsing" flag in brave://flags.

The design is the interesting part. AI browsing happens only in an isolated browsing profile, so the agent never sees the cookies, logins and cache of your main profile. A second model checks each action the agent wants to take against what you asked, without reading raw page content, which lowers the risk of a page hijacking the agent. Brave calls it a guardrail that reduces risk without removing it. Leo also lets you run your own AI models, local or remote.

Leo Premium costs $14.99 a month or $149.99 a year, with a 7-day free trial. The yearly plan saves $29.89 against twelve monthly payments.

Who it's for: a privacy-minded user who wants to try an agent without exposing their real accounts. Skip it if you want a finished feature: this one is still behind a flag.

The risk: an isolated profile also means the agent starts logged out everywhere. Tasks that need your accounts take more setup than in Comet or Chrome.

BrowserOS is an open source agentic browser that describes itself as an alternative to ChatGPT Atlas, Comet and Dia; its current version, BrowserOS neo, is a second browser for your AI agents that sits next to Chrome rather than replacing it. It's a Chromium fork, free to download, and released under the AGPL-3.0 license, which we read: it's a real open source license, with the obligation to share your changes if you distribute a modified version or run it as a network service.

Its angle is to let your AI drive the browser. Any AI that speaks MCP can connect, so you can hand web tasks to Claude Code, Codex or another MCP agent. Agents run in parallel in their own tabs, and you can watch live or replay any session like a video. Sessions, screenshots and history stay under a local folder on your machine; anonymous usage events are sent by default, never URLs, prompts or page content, and you can turn them off in Settings.

It runs on macOS, Windows and Linux, where builds are x64 (AppImage or DEB). If you only want Claude to work in the Chrome you already use on a Mac, the Control Chrome connector for Claude opens, reads and reloads tabs without a new browser. For more on what an agent is and isn't, see our AI agent glossary entry.

Who it's for: a developer or a technical team that already pays for an AI agent and wants a browser it can control, with no new subscription. Skip it if you want a polished assistant out of the box.

The risk: one click imports your Chrome logins so agents work in your real accounts, the opposite of Brave's isolated profile, so import only what the task needs. And a small open source project moves fast and breaks things. Pin a version for anything that matters, and read the release notes before updating.
