Your Android phone can become a true personal assistant powered by artificial intelligence., capable of helping you with daily tasks, answering questions instantly, and automating actions by voice or text. Without needing to be a technical person, today you can take advantage of assistants like Google Assistant, Gemini, ChatGPT, or Microsoft Copilot to simplify your daily life from your phone screen.
AI is now integrated into your mobile experience and is more accessible than ever.From setting medication reminders to writing messages in different styles or generating images in seconds. Below you'll find a complete, step-by-step guide with practical examples to activate, configure, and get the most out of the main AI assistants on Android.
What you can expect from an AI assistant on Android
Android lets you choose which assistant to use and change it whenever you want, which opens the door to different experiences: Google Assistant (classic), Gemini (Google's new offering with advanced reasoning capabilities), ChatGPT, and Microsoft Copilot. They all understand natural language, but they don't offer exactly the same things.
Gemini represents the redesign of the Google Assistant with more powerful AI models., focused on better understanding what you say and maintaining richer conversations. In internal testing, it has been observed to interpret natural language more accurately, and Google continues to improve it with frequent updates.
Assistant remains very reliable in tasks integrated with the system (alarms, calls, basic reminders, control of compatible devices), while Gemini excels most in content generation and editing and its conversational flexibility. If you're interested in conversing with AI and exploring different formats (text, voice, and image), Gemini is a step up from the classic assistant.
ChatGPT and Copilot also make the jump to "digital assistant" mode on Android. Through its apps, they offer voice and quick access features, although their integration with the system is still limited compared to Google's options. Still, they allow for immediate responses, creativity, and, in the case of Copilot, image generation within the same interface.
Set up Google Assistant and Gemini as your primary assistant
If you want to start with the most direct way on Android, activate the Google Assistant that already comes on the phone. and decide whether to stick with Assistant or upgrade to Gemini. The process is simple and designed so you can switch whenever you want.
Activate Google Assistant on Android It's as simple as opening the Google app, tapping your profile icon (top right), and going to Settings > Google Assistant. Make sure voice or button activation is enabled so you can invoke it whenever you need.
If you prefer to try Gemini as your primary assistant, install the Gemini app from Google Play and set it up for the first time (accept the terms and complete the brief onboarding process). Then, in your phone's Settings, go to Google > Google app settings > Search, Assistant & voice > Google digital assistants, and select Gemini. On some phones, you can also activate Gemini from the Google app itself or from the Gemini app, depending on your version.
Ways to chat with Gemini on mobileYou can type in the app using the keyboard and press Send; speak with your voice; or send images for the AI to interpret. There's also a conversational overlay that appears when you say "Hey Google" or manually activate Gemini, allowing you to interact without switching apps.
Switching back to Assistant or switching between the two is just as easy.: In the same Settings path, you can switch from Gemini to Google Assistant whenever you need to. Keep in mind that disabling location on your device will affect features like the weather and nearby place results in Search and the Google app.
Note for iPhone usersWhile we're focusing on Android here, if you ever switch platforms, you can enable Siri on iOS by going to Settings > Siri & Search and enabling "Hey Siri." The experience isn't identical to Android, but it shares the same idea of controlling your phone with your voice.
Use ChatGPT as your default assistant on Android
ChatGPT can also act as your voice assistant on Android If you install the beta version and select it as your system's digital assistant, it's a powerful option for everyday questions, quick responses, and more natural conversations, even with the app running in the background.
Access to the ChatGPT betaSign up as a tester by clicking the “Become a tester” button on the app's testing page. Wait a few minutes and search Google Play for an update to the ChatGPT beta version. This step is key to enabling the voice assistant feature.
Enable background voice conversations: Open ChatGPT, go to Settings by tapping your name (at the bottom of the sidebar), go to Voice, and enable “Background Conversations.” This way, you can talk to ChatGPT even if the app isn’t in the foreground.
Start a voice chat: On the ChatGPT main screen, tap the voice chat icon (in the text box at the bottom right). Let it load the advanced voice and check that it understands you correctly before setting it as your system assistant.
Set it as your default Android assistant- Go to Settings > Apps > Choose default apps > Assistance & voice input (name may vary by manufacturer) and select ChatGPT as your digital assistant. From now on, holding down the power button to summon the assistant will bring up ChatGPT ready to assist you. If something goes wrong, uninstall and reinstall the ChatGPT app to force the setup.
Microsoft Copilot as an assistant: what it can and can't do
The Microsoft Copilot app, in its beta version, can now be set as the default assistant on Android., so you can invoke it just like you would the Google Assistant, but with direct access to the chatbot and AI image generation.
Installing the betaSearch for "Microsoft Copilot" on Google Play, install the app, and request access to the beta from its listing to receive the development update within a few minutes. Alternatively, you can download the beta from APKMirror if you know what you're doing and accept the risks of installing third-party APKs.
Choose Copilot as your system assistant: Go to Settings > Apps > Choose default apps > Digital assistant app > Device assistance and select Copilot. In many Android versions, the names are almost identical, so you shouldn't get lost.
How to summonYou can launch Copilot with the same gestures as Google Assistant (holding down the power button, double-tapping the power button on some models, or swiping from the bottom corners, depending on your settings). However, it doesn't currently respond to voice commands like "Ok, Copilot."
What it offers and its limits: You'll get immediate conversational responses and image generation right from the screen by typing a prompt. However, Copilot isn't as integrated with Android as Assistant or Gemini, and there are some system tasks it can't perform (for example, creating calendar events directly from a voice command, at least not yet).

Practical examples and tricks: reminders, messages and more
One of the most useful uses of the assistant on mobile is managing reminders., especially for repetitive tasks like daily medication. Using your voice or typing, you can set reminders, change them, and delete them in seconds.
Example: Daily medication reminder at 9:00If you're using Google Assistant on Android, invoke it by saying "Ok Google" or holding down the Home or Power button (depending on your model). Then say, "Remind me to take my medication every day at 9 a.m." The Assistant will confirm and save it to your reminders list or calendar, depending on your settings.
Editing or deleting the reminder is just as quick.: You can say “Ok Google, set the medication reminder to 10 a.m.” to change it, or “Ok Google, remove the medication reminder” to delete it. The notification will automatically pop up at the specified time each day.
If you use an iPhone at some point and want something equivalent, you can say “Hey Siri, remind me to take my medication every day at 9 a.m.” and Siri will add it to your Reminders, although remember that we are focusing on Android and its main assistants here.
In addition to reminders, assistants on Android cover many more daily needs.: send dictated messages, search for information (weather, movies in theaters, quick questions), open applications, make calls by contact name or set alarms with a natural phrase like “Wake me up tomorrow at 7.”
Gemini brings additional benefits to chatting via text, voice, and images., and can appear as an overlay when you say “Hey Google” or manually activate it. If you want to control which assistant you use, you can switch between Assistant and Gemini in Settings whenever you want. Keep in mind that turning off location limits features like weather forecasts and nearby results.
With all of the above, you have a clear roadmap: activate Assistant or upgrade to Gemini from Google settings, make ChatGPT or Copilot your default assistant if you're looking for a more conversational approach, and implement practical applications such as reminders, messages, or on-the-fly searches. As Google and other providers refine their apps, you'll see how your Android's assistant becomes more personal, more capable, and more useful in your daily life.
