Google AI Push: Gemini in Chrome Unveiled

At Google I/O 2025, Google introduced Gemini in Chrome, embedding its Google AI Gemini Nano model directly into the browser. This integration allows developers to build AI in Chrome applications, such as extensions for text translation, proofreading, and summarization, without cloud dependency. Available to Google AI Pro and AI Ultra subscribers, as well as Chrome Beta users, since May 21, 2025, the feature enables tasks like summarizing web pages or analyzing YouTube videos in real time.

Google’s director of Chrome product management, Charmaine D’Silva, demonstrated how Gemini in Chrome can list key features of a product on a retail website or navigate recipe sites, highlighting its potential to streamline user tasks.

A Threat to Browser Competition

Mozilla has raised alarms about Google AI Gemini integration, warning that it could disrupt browser market competition. Brian Grinstead, a senior principal engineer at Mozilla, stated, “The browser choice of AI model has the potential to make the user experience worse in Firefox and other browsers.” He argues that developers may optimize applications for Gemini, leading to inconsistent performance across browsers and nudging users toward Chrome.

This concern echoes historical browser wars, where websites optimized for Internet Explorer or Chrome marginalized competitors. Mozilla fears that AI in Chrome could create a similar monoculture, limiting consumer choice and stifling innovation.

Google Defense:

Google has countered Mozilla’s claims, asserting that Gemini in Chrome is a technical advancement, not a monopolistic strategy. Software engineer Domenic Denicola emphasized, “We’re not trying to pick winners,” and invited dialogue to address implementation concerns. Google highlights that Gemini in Chrome enhances user experience with privacy-focused, on-device AI processing.

However, developers remain skeptical, noting that seamless AI in Chrome features may push them to prioritize Chrome for compatibility, inadvertently reinforcing Google’s dominance in the browser market competition.

Features of Gemini in Chrome: 

The Google AI Gemini integration offers a suite of Chrome AI APIs for developers, including:

• Text summarization
• Language detection
• Proofreading and writing assistance
• Real-time video analysis (e.g., identifying tools in YouTube videos)

These Chrome AI features are accessible via a sparkle icon in Chrome’s top-right corner, opening a chatbot window that interacts with webpage content. For example, users can ask Gemini to summarize an article or modify a recipe. Future updates will enable Gemini in Chrome to work across multiple tabs and devices, enhancing capabilities like product comparisons.

The Browser Wars and AI Role

The browser market competition has a storied history, from Microsoft’s Internet Explorer dominance in the 1990s to Chrome’s rise in the 2010s. Google’s integration of Google AI Gemini into Chrome mirrors past strategies where proprietary features favored one browser, raising antitrust concerns. Today, with Chrome holding over 60% of the global browser market, Google’s AI in Chrome push coincides with ongoing U.S. antitrust investigations, which could lead to remedies like Chrome’s divestiture.

The rise of Google AI, including Gemini and AI-driven search features like AI Overviews, is also reshaping web traffic. As Google AI Gemini and competitors like ChatGPT provide direct answers, traditional website visits are declining, threatening digital publishers.

Implications for the Open Web

Mozilla’s critique frames Gemini in Chrome as a potential turning point. If developers prioritize Chrome AI APIs, rival browsers like Firefox may struggle to keep up, reducing user choice. Additionally, Google plans AI integration in Chrome Android, with features like Chrome AI Android extensions in development, could extend this dynamic to mobile browsing.

The Google AI ecosystem, including Gemini and Project Mariner, aims to create “agentic” AI that autonomously navigates websites, raising concerns about control over web standards. Mozilla calls for safeguards to ensure interoperability and an open AI web.

The Role of Chrome AI Extensions

While Gemini in Chrome is a built-in feature, users can also explore free AI extensions for Chrome like Merlin AI Chat or Sider: ChatGPT Sidebar for additional functionality. These Chrome AI extensions for mobile and desktop offer alternatives but may not match the seamless integration of Google AI Gemini. For developers, Chrome AI APIs provide tools to build custom applications, though access is currently limited to premium subscribers or beta testers.

Regulation and Competition

Mozilla’s opposition may influence regulators scrutinizing Big Tech’s control over web technologies. As Google AI Gemini expands into Chrome AI Android and other platforms, antitrust watchdogs may view this as a move to consolidate power. The browser market competition will likely hinge on whether Google ensures cross-browser compatibility for its Chrome AI features.

Google’s integration of Google AI Gemini into Chrome marks a bold step toward AI-driven browsing, offering powerful tools but sparking concerns about browser market competition. While AI in Chrome enhances user experience, Mozilla warns of potential lock-in that could marginalize rivals. Balancing innovation with openness requires collaboration and regulatory oversight.
