Google Assistant for Android Messages has apparently already rolled out to phones in 24 countries, if the conditions are right -- you have to have the right combination of carrier and phone.

Instead, you can summon the assistant just like you summon Google Assistant and give it instructions directly. To get started, download Perplexity AI on your Android smartphone.

Google Assistant is officially available for many Android phones now, but the rollout will take time.

Google is now changing Assistant to Gemini by default when you download the Assistant app from the Play Store or update it.

Perplexity has launched its AI Assistant for Android, offering smart features like web search and supporting 15 languages including Hindi.
