7 Best AI Browser Agents in 2026 (Tested and Compared)
An AI browser agent is software that drives a real browser for you — reading the page, clicking buttons, filling forms, and moving through multi-step tasks the way a person would. In 2026 nearly every major AI company shipped one, and they’re genuinely useful for research, shopping, form-heavy chores, and web tasks that live behind a login with no API.
They also share one honest limitation: they operate your logged-in browser session, which is powerful and brittle at the same time. Sites change, agents get stuck, and — as every vendor now warns — a malicious page can try to hijack the agent through prompt injection. So the last entry here is deliberately not a browser agent: for recurring back-office work (email, scheduling, CRM updates), driving a browser is usually the wrong tool, and a server-side automation like Carly is the safer, steadier fit. More on that below.

1. Claude in Chrome — best for multi-tab research and Claude workflows
Claude in Chrome is Anthropic’s browser extension: Claude reads the current page, clicks, types, and fills forms, and works across multiple tabs by grouping them into its own Chrome tab group (you drag the tabs you want it to touch into the group). It can record repetitive workflows, run scheduled tasks, do console and network debugging, take screenshots, and it ships with built-in knowledge of common sites like Gmail, Google Calendar, Google Docs, GitHub, and Slack.
It’s no longer a Max-only perk. Claude in Chrome is available across all paid Claude plans — Pro, Max, Team, and Enterprise — and it’s generally available inside Claude Cowork and Claude Code, with the in-browser experience still in beta.
Safety note: the extension requests 15+ Chrome permissions, including the debugger permission, and Anthropic itself describes browser use as “still risky.” Team and Enterprise admins can allowlist or blocklist sites, and Claude will pause to intervene on high-risk pages. Good hygiene: keep it out of your banking and admin tabs.
Pricing: bundled in paid Claude plans (Pro ~$20/mo, Max $100–$200/mo).

2. Perplexity Comet — best free agentic browser
Comet is Perplexity’s standalone Chromium browser with an AI assistant built into a sidecar plus a full agent mode. It launched in July 2025 as a $200/month product, but Perplexity dropped the paywall on March 18, 2026 and now ships Comet free on macOS, Windows, Android, and iOS — including agent mode, which is the part rivals usually lock behind a subscription. Handy built-in shortcuts include /tldr for page summaries, /cite for formatted citations, /fact-check, and /job-fit.
Paid tiers add horsepower rather than gating the agent: Pro ($20/mo) unlocks premium models and unlimited queries, and Max ($200/mo) adds Background Assistants — autonomous tasks that run hands-free on a schedule — plus a large monthly credit pool for Perplexity Labs and Computer.
Safety note: because Comet is your everyday browser, its agent has your logged-in sessions. That’s what makes it convenient and what makes prompt-injection risk real — don’t turn it loose on untrusted pages while you’re signed into sensitive accounts.
Pricing: free browser and agent; Pro $20/mo; Max $200/mo.

3. ChatGPT agent mode — best for async web tasks (Atlas is being retired)
Here’s the important 2026 update: OpenAI’s standalone Atlas browser is going away. OpenAI announced the retirement on July 9, 2026, Atlas stops working on August 9, 2026, and its browser-agent capabilities are being folded back into ChatGPT — into ChatGPT’s own agent mode and the new ChatGPT Work agent. OpenAI’s earlier cloud browser agent, Operator, was similarly absorbed into ChatGPT’s agent last year. So the honest way to buy OpenAI’s browser agent today is through ChatGPT, not by downloading a separate browser.
Agent mode lets ChatGPT browse the web, fill forms, and complete multi-step tasks, and ChatGPT Work runs longer autonomous jobs (spreadsheets, decks, documents) across connected apps. Agent mode is available in preview on ChatGPT Plus ($20/mo) and Pro ($200/mo), with Go and Business tiers in the mix.
Safety note: agent mode is still labeled preview, and OpenAI tells you to watch it — especially on anything involving purchases or account changes. If you rely on Atlas today, export your data before August 9.
Pricing: included in ChatGPT Plus ($20/mo) / Pro ($200/mo).

4. Gemini in Chrome — best for the Google ecosystem
Google wired Gemini directly into Chrome. A Gemini side panel is available on any tab and connects to Gmail, Calendar, YouTube, Maps, and Google Shopping, and the agentic layer — “auto browse” — handles multi-step chores like hotel and flight research, appointment scheduling, form filling, tax-document collection, subscription management, and budget-bounded “photo-to-cart” shopping.
The side panel is now free for Mac and Windows users, but auto browse is the paid tier: Google AI Pro ($19.99/mo, ~20 tasks/day) or AI Ultra ($249.99/mo, ~200 tasks/day). It rolled out first in the U.S. on desktop and Chromebook Plus, with UK desktop and Android expanding through mid-2026.
Safety note: auto browse is still previewing and is designed to stop and ask before sensitive actions like payments — a reasonable guardrail, but it means it isn’t fully hands-off.
Pricing: side panel free; auto browse via AI Pro $19.99/mo or AI Ultra $249.99/mo.
5. Browser Use and Skyvern — best for developers building custom automations
If you want to build a browser agent rather than rent one, the open-source frameworks are where the action is. Browser Use is a Python layer that connects any LLM to a real browser session and posted a state-of-the-art 89.1% on the WebVoyager benchmark; Skyvern is a computer-vision browser agent that leads on form-heavy and legacy web workflows (85.85% WebVoyager) with “no brittle selectors” as its pitch. Both are free and open source, both offer managed cloud tiers, and both are YC-adjacent, fast-growing projects with large communities.
Safety note: these give you the most control and therefore the most responsibility — you own the credentials, the hosting, and the guardrails. Great for engineering teams, overkill for an individual who just wants their inbox handled.
Pricing: open source (free) plus paid managed cloud plans.
When you don’t actually want a browser agent: Carly
Every tool above works by driving a browser UI. That’s the right approach for one-off web tasks — booking something on a site with no API, pulling data off a dashboard, filling a legacy form. It’s the wrong approach for the recurring, unglamorous work most people actually want off their plate: triaging email, scheduling meetings, updating the CRM, filing documents, chasing follow-ups. Doing that through a browser session is brittle (a site redesign breaks it), session-bound (it needs your logins), and something vendors openly call “risky.”
Carly takes the other path. It’s an AI executive assistant that connects to your apps server-side, through APIs and native connectors — not by clicking around your browser. Each Carly agent has its own name, email address, and memory: people email or text it, and it does the work underneath. And it runs in the cloud on triggers — an inbound email, a new calendar invite, a Slack message, a form submission, a schedule — so it acts the moment something happens, without you prompting it or keeping a tab open. There’s no logged-in browser session for a malicious page to hijack, because there’s no browser in the loop.
On reach, Carly leans on 260+ native integrations across 45+ categories — CRM, accounting, support, e-commerce, project management, and more — plus bring-your-own-key access to almost any app with a public API. So the practical split is simple: use a browser agent for interactive, in-the-moment web tasks you supervise; use Carly for the repeatable back-office workflows you’d rather never think about again.
Pricing: Free, unlimited Zapier-style workflows; AI agents from $35/month.

Frequently Asked Questions
What is an AI browser agent?
An AI browser agent is software that operates a web browser on your behalf — reading pages, clicking, typing, and filling forms to complete multi-step tasks like research, shopping, or booking. Examples include Claude in Chrome, Perplexity Comet, ChatGPT agent mode, and Gemini’s auto browse in Chrome.
Are AI browser agents safe to use?
They carry real risk. Because an agent acts inside your logged-in browser, a malicious or manipulated page can attempt to redirect it through prompt injection, and agents can misfire on sensitive actions like payments. Anthropic openly calls browser use “still risky,” and OpenAI and Google both keep humans in the loop for sensitive steps. Keep agents away from banking and admin tabs, and for recurring back-office automation prefer a server-side, API-based tool like Carly that has no browser session to hijack.
Is Perplexity Comet free?
Yes. Perplexity dropped Comet’s paywall on March 18, 2026, and the browser plus its agent mode are free on macOS, Windows, Android, and iOS. Pro ($20/mo) and Max ($200/mo) add premium models, unlimited queries, and scheduled background tasks.
Is ChatGPT Atlas still available?
No — OpenAI announced Atlas’s retirement on July 9, 2026, and the browser stops working on August 9, 2026. Its browser-agent features are moving into ChatGPT’s agent mode and the new ChatGPT Work agent, so the way to use OpenAI’s browser agent now is through ChatGPT (Plus $20/mo or Pro $200/mo). Export any Atlas data before it shuts down.
Is Carly an AI browser agent?
No, and that’s intentional. Carly connects to your apps server-side through APIs and native connectors rather than driving your browser, so it’s more reliable and safer for recurring work. It gives each agent its own email address and runs on triggers (incoming email, calendar invites, Slack messages, schedules) — the right tool for automating email, scheduling, and CRM tasks, not for one-off web browsing.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
