Google has reigned absolute as a search engine for over two decades, with around a 90% share of the global market and a consolidated presence in the daily lives of billions of people. Not by coincidence, its strength also spreads to Google Chrome, a browser that dominates around 70% of global usage. But this reign is starting to be challenged in a concrete way.

On one hand, Google is investing heavily in generative AI with Gemini, which is already integrated into several of the company's products. On the other hand, independent initiatives are emerging that propose to completely change the search experience. Among them is Arc Search, developed by The Browser Company, which promises to transform the way we interact with the web: instead of infinite blue links, complete, personalized, and AI-optimized answers.

The question is inevitable: are we facing the first real threat to Google's hegemony on the internet?

What is Arc Search and where did it come from

Arc Search was born as a natural extension of the Arc Browser, launched in 2022 by The Browser Company. The browser was already drawing attention for its different proposal, with features like vertical tabs, facilitated multitasking, native tracker blocking, and advanced page customization.

But the big leap came with the mobile version. Instead of offering just a traditional browser for iOS and Android, the company created Arc Search, an app focused on AI-driven search. Unlike Google, which shows pages for the user to decide where to click, Arc Search automatically curates the web, summarizing content, citing sources, and organizing results in an interactive way.

How Arc Search works in practice

The differentiator of Arc Search is the "Browse for Me" mode, which works similarly to solutions like Perplexity AI. The user types a question and, instead of opening dozens of links, the browser searches on its own, analyzes content, and delivers a structured answer.

These answers include:

• Objective summaries, eliminating the need to open multiple websites.

• Source citations, ensuring transparency and reliability.

• Suggestions for continuity, allowing to deepen the topic in seconds.

In practice, Arc Search transforms the browser into an active digital assistant, reducing the time spent on traditional browsing and centralizing the process into a single interface.

Why this threatens Google's hegemony

Google was built on the logic of traffic redirection: the more links the user clicks, the more ads can be displayed, and more revenue is generated. The business model is worth billions precisely because it is based on advertising.

Arc Search, on the other hand, breaks this logic. It delivers the ready answer without requiring the user to go through several intermediary sites. This represents a direct threat to the financial heart of Google, which depends on exposure and ad clicks.

It is no wonder that Google accelerated investments in Gemini: the giant knows that if users start to prefer AI browsers that summarize the web instead of indexing it, its business model could be called into question.

Features that make Arc Search attractive

In addition to the AI search engine, Arc Search inherits several praised functions of the Arc Browser. Among the main highlights are:

• Simplified multitasking: vertical tabs, screen splitting, and automatic organization with AI.

• Spaces: creation of separate workspaces (personal, professional, studies), each with its own configuration.

• Customization with Boosts: possibility to alter colors, fonts, and even page elements permanently.

• Native ad and tracker blocking, without the need for additional extensions.

• Easel: native tool to save, annotate, and share web content, functioning as an alternative to Pocket.

These features create a more fluid and personalized experience than Chrome, which prioritizes integration with Google services but has evolved little in terms of usability in recent years.

The limits of Arc Search

Despite the enthusiasm, Arc Search still faces important barriers:

• Learning curve: users used to the Chrome/Google standard may find the different proposal strange.

• Memory consumption: just like Chrome, it is based on Chromium and can become heavy under intense multitasking.

• Limited compatibility: not all features are available equally across all platforms.

• Trust model: for now, the reliance on AI curation may generate distrust regarding the neutrality and accuracy of information.

These points show that, although promising, Arc Search is still far from being a definitive solution.

Google strikes back: the bet on Gemini

Gemini is Google's main strategy to maintain its leadership in a landscape where artificial intelligence redefines how we interact with the internet. More than a chatbot, it is a generative AI platform integrated into Chrome, Google Search, and the company's entire product ecosystem.

A concrete example of this move is the launch of the AI Mode in Portuguese, now available both on desktop and on Google apps for Android and iOS. The tool, previously restricted to English, goes beyond "AI Overviews" and offers in-depth answers, with follow-up questions, useful links, and the ability to interact through text, voice, camera, and images uploaded by the user.

Based on Gemini 2.5, the AI Mode is capable of handling complex searches, such as planning trips, generating comparative tables, or finding specific local information (e.g., street markets in São Paulo that open before 8 AM). All this with the advantage of presenting more contextual and organized results, without relying on multiple manual searches.

In addition, Google has been expanding Gemini's features in Chrome, including:

• Multitasking agent: which summarizes content, compares information in different tabs, and even remembers pages already visited.

• Integration with Calendar, YouTube, and Maps: allowing to schedule meetings, access videos, or search routes without leaving the current tab.

• AI-driven security features: such as detecting tech support scams, malicious notifications, and a "password agent" function capable of changing compromised credentials.

With this, Google makes it clear that it does not intend just to defend its market position, but to revolutionize search with artificial intelligence embedded in every step of the user journey.

The impact of AI on search engines

The rise of Arc Search is just a symptom of a larger trend: the radical transformation of how we search for information. The logic of "type, click, and browse" is giving way to a model of "ask and receive complete answers."

This brings profound consequences:

• Reduced traffic to smaller sites that rely on organic search to survive.
  
  

• Change in the advertising market, as ads need to be reinvented for AI contexts.
  
  

• Democratization of information, with direct answers that eliminate technical barriers for common users.
  
  

• A new role for SEO, which shifts focus from just ranking on Google to optimization for AI systems.
  
  

This movement redefines how businesses, users, and content creators relate to digital information, opening up space for new models of interaction and value on the internet.

Will it be the end of the Google era?

Arc Search represents a significant change in a model that, for a long time, seemed unshakable. For the first time in decades, Google's dominance is put to the test in a practical way.

It is still too early to talk about replacement, but the dynamics of competition have changed: the challenge is no longer about who indexes more pages, but rather about who delivers more complete, reliable, and contextualized answers.

Whether through Arc Search, Gemini, or new solutions yet to come,
