The 5 Most Powerful Agentic AI Browsers You Can Try Today

The way we browse the internet is on the brink of its biggest transformation since the arrival of the smartphone. A new generation of AI-powered browsers is emerging, designed to move beyond searching and clicking to actively carry out tasks on our behalf.

These so-called agentic browsers can see what is on our screens, understand natural-language instructions and take action across websites and apps, from researching and summarizing information to filling out forms, shopping, booking travel and managing online services. While the technology is still early and experimental, it offers a compelling glimpse into a future where browsing the web becomes far more autonomous, proactive and intelligent.

ChatGPT Atlas

ChatGPT is responsible for kicking off the current AI boom, introducing the world to large language model-powered chatbots augmented with advanced functions like image generation, information retention (memory) and reasoning. Now with ChatGPT Atlas, it’s taking another leap forward to bring us agentic web browsing.

Perhaps the main thing setting Atlas apart from the competition is the fact that it’s powered by GPT-5. OpenAI’s most advanced model is among the most capable and flexible of the current generation of LLMs, and the best suited to a wide range of everyday tasks.

Using Atlas can be quite an eye-opener if it’s your first experience of agentic browsing. Once you activate Agent Mode, you can give it instructions through the Ask ChatGPT sidebar and sit back as it opens pages, fills forms and completes tasks using its own mouse and keyboard. Just like you’ve handed control of your computer to a robot and it’s doing your work for you.

Atlas has its own browser memory, similar to ChatGPT’s ability to store and recall facts, that it uses to build up an understanding of the tasks you need it to perform. Currently, Agent Mode is restricted to Pro or Plus-tier users with a paid subscription and is only available on macOS, but that’s sure to change in the near future.

Opera Neon

Neon is another agentic browser, this time built on Opera’s Aria browser AI, which, like ChatGPT, understands natural-language prompts, generates images, and can see and interact with your screen using computer vision.

One thing that sets it apart is its focus on privacy. This is implemented through a hybrid processing model. Aria intelligently balances processing between cloud and local compute resources, with tasks involving sensitive data and private communications handled on-device, while more demanding workflows are offloaded to cloud computing infrastructure.

Potential users should be warned, however, that this focus on data security doesn’t negate the privacy concerns surrounding agentic browsing in general; more on this below.

However, it’s an encouraging sign that agentic browser developers understand that the need for privacy and security is exponentially greater when we’re dealing with agentic technology that can make decisions and even spend our money on our behalf.

Perplexity Comet

Perplexity might not have the household-name recognition of OpenAI and ChatGPT, but its search-focused generative AI has established a reputation as a powerful and flexible contender. Now it’s taken the natural next step of expanding it into a full browser product, built from scratch around the agentic browsing concept.

Originally developed as an “answer engine” designed to challenge the dominance of traditional search engines like Google, as a browser, Perplexity can now carry out autonomous tasks like shopping, managing calendars and drafting emails. Its usefulness as a research tool, which allows it to open multiple tabs and amalgamate information from multiple sources, is frequently cited as a differentiator between Comet and its competitors in the agentic browser space.

Manus

Manus, developed by Singapore-based Butterfly Effect, is slightly different from the other agentic browsers covered here, and some might argue against its inclusion. But as it can be used for similar tasks, I decided it was worth covering.

Rather than a straight-up agentic browser, Manus is described as a “browser in the cloud”. We still give it instructions through the usual natural language interface, this time powered by Butterfly’s proprietary Monica LLM. However, rather than it carrying them out through our browser, it spins up its own browser in a cloud computing session, which we can watch operate.

Manus is truly agentic, in that we give it goals and it formulates plans for achieving them and carries out actions on our behalf. It’s particularly powerful at coding tasks, where it can create and maintain multiple files, logically process our instructions for what it should do, and pull in resources from across the internet.

So, while it isn’t exactly an agentic browser in the way of the others covered here, its web-based approach to autonomously completing complex tasks means it’s worth keeping an eye on.

Agentic Browsers Vs Browser Agents

As you’d expect, most browser companies are developing agentic versions of their popular products, including industry leaders Google and Microsoft. Gemini in Chrome adds some agentic functionality, such as understanding the content of web pages, while Edge with Copilot has similar features but also stops short of full agentic capabilities. This means they’re better described as “browser agents” rather than true “agentic browsers”.

Other newcomers include Brave Leo, which isn’t yet fully agentic but does stand out thanks to its focus on private and secure browser agent functionality, as well as Dia Browser.

The Agentic Everyday

This is a fast-moving field of technology, and by the time you’re reading this, other contenders may have emerged in the race to pioneer the next generation of web browsing.

It’s also worth remembering that these are very early days, and all the technologies described here are at a stage best described as “experimental”. Although undoubtedly impressive, in practice, you’re likely to find that browsing the old-fashioned way gets faster and more reliable results for now. This is less true for simple tasks like research or summarizing, and more true for complex jobs involving accessing and coordinating multiple online tools and resources.

Finally, one hugely important caveat is the issue of privacy and security. As this technology is very experimental, no one is entirely sure exactly how safe it is. As a final word of warning, I’d strongly caution against putting any sensitive information, like banking details or passwords, into any AI that can’t guarantee total privacy, backed by robust external audits, which is something none of them can yet do.

Having said that, as long as you’re just experimenting safely, this early wave of agentic browsers offers a fascinating insight into how AI will change how we use the internet over the coming years.
