Google’s Chrome browser has continued to embed its Gemini‑based AI across platforms. After the July rollout of the “Select from screen” tool in Chrome 150 and the July 23 update that added @gemini invocation, Chrome 151 entered Stable in late July, bringing security fixes, removal of Manifest V2 and dynamic patching.

In early August the company clarified that on‑device Gemini models (the 4 GB Gemini Nano) are downloaded only when a device has roughly 20 GB of free storage. Chrome reserves additional space for unpacking and future updates, checks for an unmetered connection and sufficient hardware, and allows users to disable the “On‑device AI” toggle to delete the model and stop background downloads.

UI refinements are also being rolled out: Android Chrome now uses a dual‑bar layout with a bottom‑bar Gemini shortcut for one‑hand use; Wear OS devices such as the Pixel Watch receive an overlay interface that places Gemini over the watch face; and an experimental “Device Help” feature on Pixel phones lets users describe problems in natural language and receive targeted settings adjustments via Gemini.

On 7 August 2026 Google began a gradual rollout of a redesigned Chrome for Android. The update replaces the previous navigation bar with a single bottom toolbar that merges navigation controls and adds a dedicated Gemini button for instant AI access. The rollout is limited to a subset of devices and varies by region – U.S. users see the Home button swapped for the Gemini shortcut, while other markets retain a three‑button layout alongside the address bar. The change follows earlier July UI experiments and aligns with Google’s plan to phase out Google Assistant later in the year.

These steps deepen Gemini’s integration while giving users clearer control over storage and privacy implications.
