Gemini, Google’s generative AI assistant and rival to ChatGPT, has become integral to high-end Android phones over the past year, gradually superseding the more basic Google Assistant. Now Google has outlined plans to sunset its original smart assistant entirely, starting with Android phones.

The transition to Gemini is already underway, with millions of users having made the switch, the company said in a blog post.

After just nine years, Google is moving Assistant to the graveyard. Last fall, Google announced it was officially replacing Assistant, the default Android assistant on your phone, with Gemini. You still had the option to use Assistant, but now that option is ending and users must move to Gemini.
