Top 10 Best AI Browsers in 2025: Features, Comparison,

The web browsing experience is rapidly evolving. Traditional browsers served pages; smart browsers of 2025 aim to assist, automate and augment your browsing with built-in artificial intelligence. Whether you’re a creator, developer, researcher or casual user, the right AI-powered browser can save time, streamline tasks and help you make sense of the web. In this post we’ll review the top 10 AI-powered web browsers for 2025, compare their features side-by-side, highlight pros & cons, and help you pick the right one for your needs.

Top 10 Best AI Browsers in 2025

Here’s a detailed look at each browser, what makes it stand out, and any caveats.

1. Microsoft Edge (Copilot)

With the introduction of Copilot Mode in Edge, Microsoft has transformed Edge into a full-fledged AI browser: “When enabled … your requests will get smartly routed to search, chat, or web navigation.
Copilot can summarise open tabs, assist with writing, respond via chat/voice, and more.
Major advantage: deep integration with the Windows/Office ecosystem, mature browser base.
Things to consider: Some AI features may still be labelled “experimental” or require opt-in; privacy/permissions need checking.

2. Sigma AI Browser

Billed as “the most innovative AI browser with built-in AI chat, enhanced privacy, advanced search capabilities, and AI-powered content generation.”
Offers features like “Deep Research mode”, an AI agent that logs into sites and completes tasks (e.g., bookings, inbox clean-up) for you.
Strong focus on creators, automation and privacy.
Consideration: Newer products might have fewer community/user reviews and integrations.

3. Dia Browser

Developed by The Browser Company, Dia is an “AI browser … Chat with your tabs, write in your own voice, learn and plan faster …
Key uses: writing, learning, planning, shopping — in-line copy editor, instant summaries, tutoring.
Best for users who want assistance while doing heavier tasks like writing and research.
Potential drawbacks: As a newer browser, it may have less extension or ecosystem support than mainstream browsers.

4. Fellow.ai

Marketed as “the world’s first agentic browser” that automates complex tasks with “Deep Action” technology.
The shift here is from “assist” to “”act”—the AI doesn’t just help you browse, it executes tasks.
Best for power users wanting automation (e.g., inbox cleaning, workflow automation).
Caveat: Higher complexity; may require a steeper learning curve; also less widely known.

5. Opera One

Opera’s AI offering (codenamed Aria) is built into Opera One: “Aria delivers real-time answers, recognises and generates AI images, manages your tabs and more … for free, and no account is needed.
Very user-friendly for those familiar with Opera; a good mix of AI features and browser maturity.
Considerations: Browser market share is smaller than Chrome/Edge; some features may require an account or be region-limited.

6. Arc Browser

While not strictly labelled “AI browser” in every article, Arc is known for productivity-centric browsing, sidebar tools, and emerging AI features (via integrations).
If you emphasise creators/designers like yourself (you’re a graphic designer & video editor), Arc may be appealing for its unique UX.
But: less focused on built-in AI agents compared to some others here — worth verifying the current AI feature set.

7. Brave Browser

Brave introduced its AI assistant “Brave Leo” built into the browser: “Ask questions, summarise pages, create new content, and more. Privately.”
Strength: Strong privacy focus, ad-blocking, alternative search engine; a good option for privacy-conscious users.
Trade-offs: the AI feature set may lag behind the latest “agentic” browsers; some premium features may cost money.

8. Perplexity Comet

Designed as an “AI-powered web browser based on Chromium… the browser that works for you.”
Features: contextual awareness across tabs, natural-language prompts for tasks, research-friendly.
Important: Still emerging, with some security/privacy warning signs.
If you’re keen to experiment and push boundaries, Comet is interesting.

9. ChatGPT Atlas

I couldn’t locate a strong public reference for a browser named “ChatGPT Atlas” in my search. It’s possible you meant “Atlas” as a feature of ChatGPT or a browser with “Atlas” as a codename.
Suggestion: If you indeed meant a browser, verify its name and features before including it. If not, you might substitute another AI browser like “Arc” or perhaps “SigmaOS / SigmaOS AI”.

How to Choose the Right AI Browser for You

Here are some criteria to help decide:

What tasks do you perform?
- If you browse for research, summarising multiple tabs and extracting insights, choose browsers with strong summarising & agentic features (Sigma, Comet, Edge).
- If you’re a creator (graphic designer/video editor) like yourself, look for built-in media generation and content creation support (Sigma, Opera, Dia).
- If you prioritise automation (e.g., “the browser does tasks for me”).
Privacy & trust
- For high privacy concerns: Brave is strong.
- For browsers with large vendors & ecosystems (less risk): Edge or Opera.
- For very new entrants: weigh the trade-off between innovation vs maturity/bug risk (Comet, Fellou).
Ecosystem & extensions
- If you rely on many extensions, stable updates, and a large community: Edge, Opera, and Brave.
- Newer browsers may not have much extension support or plugin compatibility yet.
User interface & learning curve
- If you want a familiar browser with added AI, Edge or Opera may feel easiest.
- If you’re comfortable experimenting and want next-gen workflow, Sigma, Comet, and Fellow may be exciting but require adaptation.
Cost & licensing
- Some features may be free, but advanced automation or AI-agentic tiers may cost or require subscription (e.g., Comet’s early-tier model).
- Always check for “free forever” vs “trial” vs “paid”.

Final Verdict

In summary:

If I had to pick one all-round winner for 2025, I’d recommend Edge (with Copilot) for most users thanks to its mature ecosystem and strong AI features.
If your focus is content creation and automation, then Sigma AI Browser and Fellow.ai offer the most advanced AI-centric workflows.
If you value privacy first, then Brave Browser is compelling.
For early adopters who like to experiment and don’t mind risk, Perplexity Comet holds big potential.
Make sure you trial a couple of browsers and see which fits your workflow best (especially since you’re a graphic designer & video editor — your ideal browser may integrate smoothly with your tools and style).

Call to Action

I’d encourage you to pick 1-2 browsers from this list, install them, test them on your actual workflows (graphic design research, video editing projects, content creation) and evaluate speed, AI assistance quality, tab management and privacy. Once you find your “daily driver”, stick with it for a week and compare it vs your old browser.

Also: I recommend updating the blog post after 3-6 months—AI browser space is moving fast (new features, subscriptions, security issues), so keeping it fresh will boost your site traffic too.
