A significant transformation is underway at Google that will impact users across the globe. The technology company is phasing out its original virtual assistant platform while simultaneously removing functionality that connects Gmail with external email services.
Beginning September 4, 2026, Google will initiate the transition from its legacy Assistant platform to Gemini across Android smartphones, tablets, Wear OS wearables, audio devices, and Android Auto-equipped vehicles. The deployment will occur incrementally over multiple weeks.
After the migration completes on any particular device, reverting to the previous Assistant platform will no longer be possible.
The Rationale Behind Google’s Transition
Google initially revealed its intention to migrate users from Assistant to Gemini in March 2025. Brian Marquardt, who serves as Senior Director of Product Management, noted that millions had already voluntarily adopted the new platform.
Gemini represents a significant advancement beyond traditional voice-activated commands. The platform can create original content, respond to contextual inquiries, condense information, and integrate seamlessly with Google’s ecosystem of applications.
The original Assistant, which debuted in 2016, was engineered primarily for straightforward operations such as reminder creation, weather inquiries, and smart home management. In contrast, Gemini, unveiled in 2023, supports extended, sophisticated dialogues.
During the second quarter of 2026, the Gemini application recorded 950 million monthly active users. The number of daily active users grew by 200% year-over-year.
Google continues to broaden its Gemini model portfolio. Recent launches include Gemini 3.5 Flash Cyber, while Gemini 3.5 Pro undergoes testing and Gemini 4 enters the pre-training phase.
Gmail Feature Removals Scheduled for January 2027
In a separate announcement, Google revealed plans to discontinue two Gmail capabilities. The “Send as” functionality, which enables users to dispatch emails from external providers including Yahoo, Outlook, and Hotmail through the Gmail interface, will cease operations in January 2027.
Additionally, Gmailify—a service that applies Gmail’s features like spam detection and inbox categorization to external email accounts—will be discontinued simultaneously.
Google attributes this decision to security optimization and reduced maintenance overhead. Users can expect notifications within the product interface throughout the Q3 2026 announcement window.
A transition window spanning Q3 and Q4 2026 will precede the shutdown. While new configurations may face limitations during this period, currently active setups will remain functional until the January 2027 deadline.
Google has not disclosed a timeline for bringing Gemini to Google TV platforms, Home speakers, or smart display devices. These products currently continue operating with the Assistant platform.
Gemini’s web-based application supports over 70 languages and is accessible in 230 countries and territories worldwide.
