1. Perplexity Comet: The Free Research Powerhouse

Launch Date: October 2, 2025 (free for everyone)
Platform: Windows, macOS, Linux
Price: Completely free

Perplexity Comet became free worldwide on October 2, 2025, after initially launching exclusively for Max subscribers at $200 per month in July 2025. This makes it the most accessible Atlas alternative available today.

What Makes Comet Stand Out

Comet’s biggest strength is its answer engine that provides summarized, cited answers instead of a list of links. Every response includes source citations, making it ideal for research work where accuracy matters.

The browser includes a sidecar assistant that helps answer questions about the web page you’re on, summarize content, manage web content, and navigate web pages on your behalf.

Key Features

• Source citations on every answer – Perfect for students, journalists, and researchers who need to verify information
• Multi-platform support – Works on Windows, macOS, and Linux right now
• Integrated tools – Discover, Spaces, Shopping, Travel, Finance, and Sports tools built in
• Context retention – Maintains context across tabs for cumulative research

Who Should Choose Comet?

Pick Comet if you:

• Need a free alternative that’s available right now
• Use Windows or Linux (Atlas isn’t available on these platforms yet)
• Prioritize research and need proper source citations
• Want full functionality without paying a subscription

Real User Experience

When Perplexity users first downloaded Comet, the number of questions they asked increased by 6-18 times in the first day, suggesting the tool naturally encourages exploration and research.

The Catch

While Comet is completely free, the company’s CEO has stated plans to track user activities across the internet through the browser to build user profiles for advertising purposes. If privacy is your primary concern, you might want to consider Brave instead.

2. Microsoft Edge with Copilot Mode: The Windows Native Choice

Launch Date: July 28, 2025
Platform: Windows, macOS
Price: Free

Microsoft launched Copilot Mode on July 28, 2025, as an experimental mode in Microsoft Edge, bringing AI capabilities directly into Windows’ default browser.

What Makes Edge Copilot Mode Stand Out

The advantage of Edge is its deep integration with Windows and the Microsoft ecosystem. Copilot Mode brings features like a streamlined new tab page to start a chat, search or navigate the web, reasoning across multiple open tabs with ease, and a dynamic pane that helps you keep the context of your webpage.

Key Features

• Multi-tab context awareness – Copilot sees the full picture across your open tabs, and you can even instruct it to handle some tasks
• Copilot Actions (Preview) – Allows Copilot to take control and interact with the web for you, and conduct a task on your behalf
• Copilot Journeys – Allows Copilot to remember your browsing history and create ‘journeys’ that you can pick back up from anywhere
• Voice-only navigation – Enables hands-free browsing
• Free to use – No subscription required for core features

Who Should Choose Edge?

Pick Edge with Copilot Mode if you:

• Use Windows as your primary operating system
• Already use Microsoft 365, Outlook, or OneDrive
• Want AI features without paying anything
• Need good integration with Windows features
• Prefer established companies with strong privacy policies

Real-World Performance

You can compare recipes across multiple tabs, summarize the instructions and create a cooking schedule that maximizes your single oven time. The multi-tab reasoning capability makes Edge particularly useful for research and comparison tasks.

Privacy and Control

Microsoft only collects the data needed to improve your experience or that you choose to provide via Personalization settings, so you’re always in control. You can toggle Copilot Mode on or off anytime through browser settings.

3. Opera Neon: The Premium Automation Expert

Launch Date: September 30, 2025
Platform: Windows, macOS
Price: $19.99/month

Opera launched its AI-centric browser Neon on September 30, 2025, with the ability to create apps through AI prompts and create repeatable prompts through a feature called “Cards”.

What Makes Opera Neon Stand Out

Neon is the only major AI browser charging a monthly subscription, positioning itself as a premium tool for power users. Opera built Neon for themselves and for everyone who uses AI extensively in their day-to-day.

Key Features

• Tasks – Contained workspaces of AI chats and tabs, like Tab Groups combined with Arc Browser’s Spaces feature, which has its own context for AI
• Neon Do – Will help you get tasks done, like summarizing a Substack blog and posting the summary to a Slack channel
• Cards – Reusable prompt instructions that work like IFTTT (if this then that) of AI prompting. You can combine cards like “pull-details” and “comparison-table” to create a new prompt for comparing products across tabs
• Code generation – Can write snippets of code for visual reports with tables and charts
• Local execution – Actions happen in your browser session, not in the cloud, improving privacy

Who Should Choose Opera Neon?

Pick Opera Neon if you:

• Use AI extensively every single day
• Need advanced automation and repeatable workflows
• Value privacy-first local execution
• Don’t mind paying $19.99/month for premium features
• Want a tool built specifically for power users

The Reality Check

With free alternatives like Comet and Edge offering similar features, the $19.99 monthly price is a tough sell. You’re essentially paying for advanced automation capabilities and the Cards system for building reusable workflows.

Availability

Neon is currently rolling out through a waitlist system. You can join at operaneon.com to secure early access.

4. Dia Browser: The Simplified AI Experience

Launch Date: Beta launched June 2025
Platform: macOS, Windows (limited)
Price: Free

Dia Browser is available for use in beta from The Browser Company, though you’ll need an invite to try it out. This is the same company that created Arc Browser.

What Makes Dia Stand Out

By giving users an AI interface within the browser itself, where a majority of work is done these days, the company is hoping to slide into the user flow and give people an easy way to use AI, cutting out the need to visit the sites for tools like ChatGPT, Perplexity, and Claude.

Key Features

• AI chatbot in the URL bar – The bot can search the web for you, summarize files that you upload, and automatically switch between chat and search functions
• Tab analysis – Users can ask questions about all the tabs they have open, and the bot can even write up a draft based on the contents of those tabs
• Customizable AI – To set your preferences, all you have to do is talk to the chatbot to customize its tone of voice, style of writing, and settings for coding
• History feature (opt-in) – You can allow the browser to use seven days of your browsing history as context to answer queries
• Chromium-based – Familiar look and feel with Chrome extension support

Who Should Choose Dia?

Pick Dia if you:

• Want a simpler, more approachable AI browser than Arc
• Found Arc too complex but like The Browser Company’s approach
• Prefer a clean interface over power-user features
• Can get access to the beta (Arc members get immediate access)

Development Status

The Browser Company decided to stop developing new features for Arc and shift focus to Dia, acknowledging that while Arc was popular among enthusiasts, it never hit scale as it presented too steep a learning curve.

Dia aims to fix Arc’s complexity problem by creating something that feels more like Chrome with AI built in, rather than a radical rethinking of how browsers work.

5. Google Chrome with Gemini: The Familiar Powerhouse

Platform: Windows, macOS, Linux, Android, iOS
Price: Free

Chrome remains the world’s most popular browser, and Google has been steadily integrating Gemini AI throughout 2025.

What Makes Chrome with Gemini Stand Out

Chrome’s advantage is simple: it’s already installed on billions of devices, and most people know how to use it. The Gemini integration adds AI features without requiring users to learn a completely new browser.

Key Features

• Gemini side panel – Access Google’s AI directly in the browser sidebar
• Search integration – AI-generated summaries in search results
• Tab organization – AI-assisted tab grouping and management
• Extension ecosystem – Access to thousands of Chrome extensions
• Cross-device sync – Works across all your devices with Google account

Who Should Choose Chrome?

Pick Chrome with Gemini if you:

• Already use Chrome and don’t want to switch
• Use Google Workspace (Gmail, Drive, Docs)
• Want AI features without learning a new browser
• Need the largest extension library
• Use Android phones and want seamless integration

The Limitation

Chrome’s AI features aren’t as deeply integrated as Atlas or Comet. You’re essentially getting a traditional browser with AI tools added on top, rather than an AI-first experience.

---

6. Brave with Leo: The Privacy Champion

Platform: Windows, macOS, Linux, Android, iOS
Price: Free

Brave is the answer for users who want AI features but refuse to compromise on privacy.

What Makes Brave Stand Out

Brave is among the more well-known privacy-first browsers, popular for its built-in ad and tracker blocking capabilities. The Leo AI assistant extends this privacy-first approach.

Key Features

• Built-in ad blocking – No extensions needed
• Private AI assistant (Leo) – Uses Mixtral AI model
• Cryptocurrency rewards – When users choose to opt in to view ads, supporting their favorite websites, they get a share of the ad revenue through Basic Attention Token (BAT)
• Built-in VPN service
• Strong privacy protections – Blocks trackers by default

Who Should Choose Brave?

Pick Brave if you:

• Put privacy above all other features
• Want to block ads and trackers by default
• Like the idea of earning cryptocurrency
• Need a browser that works on all platforms
• Don’t need the most advanced AI automation

The Trade-off

Leo isn’t as powerful as ChatGPT or Perplexity’s AI. You’re trading cutting-edge AI capabilities for stronger privacy protections.

7. Arc Browser: The Design-Focused Option

Platform: macOS, Windows
Price: Free
Status: Maintenance mode (no new features planned)

Arc is now effectively in maintenance mode with no new features planned. It won’t be getting anything outside of Chromium engine upgrades, security fixes, and other as-needed patches.

Why Arc Still Matters

Despite being in maintenance mode, Arc still offers a unique browsing experience that many users love. If you’re drawn to thoughtful design and don’t need the latest AI features, Arc remains a solid choice.

Key Features

• Vertical tabs – Sidebar-based tab organization
• Spaces – Separate workspaces for different contexts
• Boost – Customize any website’s appearance
• Split view – Work with multiple tabs side by side
• Limited AI features – Basic AI assistance available

Who Should Choose Arc?

Pick Arc if you:

• Value design and user experience over cutting-edge features
• Want a unique take on browser organization
• Don’t need advanced AI automation
• Can accept that no major new features are coming
• Are okay using Arc as a secondary browser

The Reality

The Browser Company founder Josh Miller admitted Arc “fell short” of the dream to build a new widely-used Chrome alternative. The company’s focus has shifted to Dia, making Arc a dead-end for long-term use.

The Bottom Line: What Actually Works Today

The AI browser market is moving fast, but here’s what matters right now:

For most people: Start with Perplexity Comet. It’s free, it works on Windows and Mac, and it delivers real value for research and daily browsing. The source citations alone make it worth trying.

For Windows users: Microsoft Edge with Copilot Mode is the obvious choice. It’s free, it’s already installed, and the Windows integration is hard to beat.

For privacy advocates: Brave with Leo gives you AI features without compromising your privacy principles.

For Mac users willing to wait: ChatGPT Atlas will likely be the best option once it matures, but it needs time to fix bugs and add features.

Skip these for now: Opera Neon is too expensive for what it offers. Arc is a dead end. Dia is too early in beta for most users.

The truth is, no AI browser is perfect yet. They all have bugs, limitations, and areas where they fall short. The good news? Competition is fierce, which means these browsers will improve rapidly throughout 2025.

Try Comet first. It’s free, it works today, and if you don’t like it, switching to Edge or Brave takes five minutes. The AI browser revolution is here, but it’s okay to start simple and upgrade later.

Frequently Asked Questions

Is ChatGPT Atlas available on Windows?

No. Atlas is currently macOS-only, with Windows, iOS, and Android versions coming soon. No specific release dates have been announced. If you need an AI browser on Windows today, Perplexity Comet or Microsoft Edge with Copilot Mode are your best alternatives.

Which ChatGPT Atlas alternative is completely free?

Perplexity Comet, Microsoft Edge with Copilot Mode, Dia Browser (beta), Google Chrome with Gemini, and Brave with Leo are all completely free. Comet provides the most comprehensive free features, making it the best free alternative overall.

Can these AI browsers replace ChatGPT entirely?

Not quite. While these browsers integrate AI deeply, they’re designed for browsing tasks. For complex writing, coding, or creative work, you’ll still benefit from using ChatGPT directly. Think of AI browsers as companions to ChatGPT, not replacements.

Are AI browsers safe to use?

All major AI browsers face security concerns, including prompt injection attacks and data privacy issues. Microsoft Edge and Brave have the strongest security track records. Comet has faced scrutiny over data collection for advertising. Always review privacy settings before enabling AI features.

Do I need to pay for the best AI browser experience?

No. Perplexity Comet and Microsoft Edge with Copilot Mode offer excellent AI features for free. Opera Neon charges $19.99/month, but most users won’t find enough value to justify the cost when free alternatives work well.

Which browser has the best AI for research?

Perplexity Comet wins for research because every answer includes comprehensive source citations. This makes it ideal for students, journalists, and anyone who needs to verify information. Edge is a close second with good citation capabilities.

Can I use Chrome extensions in these AI browsers?

Yes, most of them. Comet, Edge, Neon, Dia, and Brave are all built on Chromium and support Chrome extensions. This means you can install your favorite extensions and use them alongside AI features.

Which AI browser works best on Linux?

Perplexity Comet is currently the only dedicated AI browser officially supporting Linux. Brave also works on Linux and includes the Leo AI assistant. Chrome with Gemini works on Linux but has limited AI integration.

Will ChatGPT Atlas be free?

Atlas is free to download for all ChatGPT account types (Free, Plus, Pro, and Go). However, Agent Mode—the most powerful automation feature—is only available to Plus ($20/month), Pro ($200/month), and Business users.

How do these browsers compare to using ChatGPT in a regular browser?

AI browsers integrate AI directly into browsing, eliminating the need to switch between tabs. They can see your current page, analyze multiple tabs simultaneously, and take actions on websites. Using ChatGPT in a regular browser requires manual copying and pasting.

Conclusion: The AI Browser Revolution Is Just Beginning

October 2025 marked a turning point. ChatGPT Atlas, Perplexity Comet, Microsoft Edge Copilot Mode, and Opera Neon all launched or got major updates within weeks of each other. This isn’t coincidence—it’s the start of a fundamental shift in how we interact with the web.

The honest truth? These browsers are all version 1.0 products. They have bugs. Features don’t always work as expected. The AI makes mistakes. But they’re also genuinely useful, and they’re improving every week.

Start with Perplexity Comet. It’s free, it works on Windows and Mac, and you can try it right now. Use it for a week. If the source citations and research features don’t win you over, try Microsoft Edge with Copilot Mode. If you’re on Mac and privacy matters most, give Brave a shot.

Don’t overthink this decision. These are all free (except Neon), and switching between browsers takes minutes. The best way to find your favorite AI browser is to actually use them.

The AI browser wars have just begun, and competition means these tools will get dramatically better throughout 2025. By this time next year, we’ll probably look back at today’s AI browsers the way we look at the first iPhone—primitive, but revolutionary.

The future of browsing is intelligent, contextual, and conversational. Whether that future is powered by OpenAI, Perplexity, Microsoft, or someone else entirely, one thing is certain: we’re never going back to the old way of browsing.

Try Comet today. Your research workflow will thank you.
