AI-Powered Browsers Ignite New Era of Web Navigation Wars

The Return of Browser Competition

The browser wars that defined the late 1990s tech landscape have returned with renewed intensity, according to industry reports, but this time the battlefield centers on artificial intelligence rather than mere speed or interface design. After nearly two decades of relative stability in web browsing technology, companies are now racing to integrate generative AI and agentic capabilities directly into their browsers, fundamentally changing how users interact with the internet.

From Navigation to Delegation

For thirty years, the basic browsing experience remained largely unchanged, with users typing URLs or search queries and clicking through links. Analysts suggest we’re now witnessing what may be the most significant shift since browsers became the primary gateway to the internet. “This is probably the biggest shift since we’ve seen the browser itself become the gateway to the internet,” George Chalhoub, assistant professor at UCL Interaction Centre, told Fortune. “For 30 years, the browser was about navigation. Type, click, explore. Now, with AI, it’s changing the model completely. It’s moving from browsing to delegating.”

Tech companies are reportedly betting that users want a browser that can answer questions directly rather than providing lists of links, and that can perform tasks such as booking travel or completing purchases without constant user intervention.

OpenAI Enters the Arena

On Tuesday, OpenAI joined the competition with its new AI-powered browser, ChatGPT Atlas. Sources indicate the browser resembles traditional interfaces like Google Chrome but positions ChatGPT at the center of the browsing experience. The company is reportedly offering a paid agent mode that can conduct autonomous searches for users, representing a significant departure from conventional browsing models.

OpenAI’s entry comes as Google’s dominance in search shows signs of weakening. According to analysts at Third Bridge, Google’s global search market share dropped below 90% for the first time in ten years this July. This decline appears connected to growing competition from AI search engines and chatbots, with surveys from brokerage firm Evercore ISI showing that the percentage of respondents naming ChatGPT as their primary search provider increased from 1% to 5% within four months last year.

The New Competitive Landscape

The current browser competition features established players and ambitious newcomers:, according to recent innovations

Google Chrome, enhanced with Google’s Gemini AI, maintains its dominant market position while integrating AI capabilities
Perplexity’s Comet combines web browsing with a built-in AI agent that can read pages, summarize information, and perform multi-step actions
Opera’s Neon introduces features like “Do” for automated actions and “Cards” for storing custom workflows
OpenAI’s Atlas positions ChatGPT as the central interface for web interaction

“The browser wars are starting and the competition is heating up because browsers today are the operating system of your applications,” Krystian Kolondra, EVP Browsers at Opera, told Fortune. “The browser world is extremely important because it is more aware than the operating system itself about what’s happening on your pages.”, according to industry reports

Technical Challenges and Chromium Dominance

Despite the AI revolution, building a browser from scratch remains exceptionally challenging. Reports indicate that nearly every “AI browser” on the market, including Perplexity’s Comet and OpenAI’s Atlas, is built on Chromium, the open-source project primarily developed by Google. Chromium serves as the back-end system that determines how browsers locate web addresses and render pages.

“It’s literally reinventing the wheel,” Chalhoub said regarding building new browser engines. “I don’t see any company building its browser from scratch.” Even Microsoft, once Google’s fiercest competitor in the browser space, eventually abandoned its own engine and rebuilt Edge on Chromium.

The Data and Privacy Implications

Agentic AI browsers have access to significantly more user data than traditional search engines, raising important privacy concerns. According to experts, these tools don’t just observe user behavior but can infer intentions, habits, and even moods based on interaction patterns.

“Browsers have always been powerful data collection tools, and when you add AI to the mix, that power multiplies,” Chalhoub warned. “An AI-powered browser doesn’t just observe your behavior; it can infer your intentions, habits, and even your mood. Every prompt or summary becomes a data point about you, so the information has to be handled responsibly.”

The privacy concerns are compounded by uncertainty around data confidentiality. OpenAI CEO Sam Altman recently acknowledged that users currently have no legal protection over their ChatGPT conversations if subpoenaed. Tech companies appear aware of these risks, with Opera’s Kolondra emphasizing that Neon only processes data when users explicitly request actions like page summarization and that all requests are end-to-end encrypted.

The Future of Web Interaction

The vision for AI-powered browsing reframes the browser from a simple access tool to the primary interface through which AI agents operate. “The whole notion of search changed,” said Himanshu Tyagi, co-founder of open-source AI company Sentient. “It’s not to point to the place where you can find your answer or do your thing, but to give you that answer and do that thing.”

This transformation may lead to what some are calling a “dark internet” – not in the criminal sense, but as an environment where bots consume and process information before presenting final results to humans. The ultimate goal for many AI companies appears to be creating autonomous assistants that can move fluidly between a user’s various applications and services.

While changing long-established browsing habits presents a significant challenge, experts suggest that practical benefits may drive faster adoption than anticipated. “If an AI browser can slowly start saving me time, booking travel automatically, or summarizing articles, I think people will adapt much faster than we expect,” Chalhoub noted.

The current generation of AI browsers represents a hybrid approach – neither fully chatbot-driven nor entirely traditional – that allows both humans and AI models to access the web simultaneously. This intermediate step may prove crucial in transitioning users toward more automated web experiences while maintaining familiar interaction patterns.
