Your Android can become a personal assistant with AI capable of understanding you, conversing with you and automating your daily life without you having to be technically savvy.From setting reminders or dictating messages to generating images or summarizing texts, today you can choose from several options: the classic Google Assistant, the revamped Gemini, the ChatGPT app and Microsoft Copilot.
The key is that Android lets you choose which AI assistant to use and switch between them whenever you want., so you can prioritize system integration (Assistant), generative and conversational capabilities (Gemini), or a more open approach with ChatGPT and Copilot. Below is a step-by-step guide, with real-life tips and all the requirements to get it right the first time.
What is an AI assistant and what does it offer on Android?
An AI assistant is software that understands natural language and performs tasks for you, by voice or text.Using language processing (NLP), machine learning (ML), and large language models (LLM), you can respond, summarize, create content, and, on Android, interact with system features.
With the Google Assistant you can do basic and very useful things without touching the screen.: ask quick questions, make calls, send text messages, set reminders, or ask for directions.
- Ask questions to obtain information at the moment.
- Call by telephone to a contact by name.
- Send SMS dictating the content.

Assistant vs. Gemini, ChatGPT, and Copilot: Key Differences
Android lets you choose the assistant and change it whenever it suits you., opening the door to different experiences with Google Assistant, Gemini, ChatGPT or Microsoft Copilot.
Gemini is the redesign of Google's AI assistant with more powerful models., better language understanding, and richer conversations that evolve with frequent updates.
Assistant remains very reliable for system-integrated tasks such as alarms, calls, basic reminders and control of compatible devices, while Gemini shines at generating and editing content and managing complex conversations with text, voice and image.
ChatGPT and Copilot work as assistants on Android through their apps., with voice access and immediate responses; their integration with the system is less than that of Google's options, but they offer creativity and, in the case of Copilot, imaging integrated.
Requirements for using the Google Assistant on Android
Make sure your device meets the basics before activating the Assistant: Android version, memory, Google app and Google Play Services.
- Android 5.0 or higher with at least 1 GB of RAM or Android 6.0 or higher with at least 1,5 GB of RAM.
- Google App 6.13 or later.
- Google Play services installed.
- 720p or higher display.
- One of the supported languages set as the device language.
Check your version of the Google app to avoid errors: Open the Google app, go to Settings, and then About. If it's older than 6.13, go to its Play Store page and update.
Verify that you have Google Play Services- On the app's Play Store page, if you see Uninstall or Disable, it means they're already there; if not, install them.
To start a conversation with the AI ​​Assistant, press and hold the Home button or say 'Hey Google.' On Android 8.0+, you can speak even when your phone is locked, controlling what's displayed on the lock screen.
The input method is also configurable: Under 'Hey Google, open Assistant settings,' you can choose Voice or Keyboard as your preferred interaction method. On Pixel 6 and later, there are quick phrases without saying 'Hey Google.'
Activate and configure Google Assistant or use Gemini as your primary AI assistant
To start on the safe side, activate the Google AI Assistant that already comes on your phone., and decide whether to stick with Assistant or upgrade to Gemini at any time.
Activate Google Assistant It's as simple as opening the Google app, tapping your profile picture (top right), and going to Settings > Google Assistant; make sure you enable voice or button input.
To try Gemini as your default assistant, install the Gemini app from Google Play, accept the terms and complete the initial setup; then go to Phone Settings > Google > Google App Settings > Search, Assistant & Voice > Google Digital Assistants, and select Gemini.
Ways to chat with Gemini on mobile: You can type, speak, or send images for AI to interpret. It also appears as an overlay when you say "Hey Google" or activate it manually.
Switching back to Assistant or switching between the two is immediate.: In the same Settings path, you can switch between Gemini and the classic AI Assistant; remember that disabling location limits features like weather or nearby places.
Availability note: The Gemini app is available in many countries, but It cannot be officially downloaded in Spain or the EU at the moment.If it doesn't appear on Google Play, you can download its APK from third-party stores at your own risk.
Requirements and behavior of the Gemini app on Android: Requires Android 12 or higher and a Google account; if you don't have the Google app installed, it will prompt you for it, and the first time you use it, it may invite you to 'switch from Google Assistant to Gemini'.
Use ChatGPT as your default AI assistant on Android
ChatGPT can act as the system's voice AI assistant if you update to its beta version. and set it as the default support app on Android.
Access the beta: Sign up as a tester using the 'Become a tester' button on the app's testing page and wait for the update on Google Play.
Enable background voice conversations: In ChatGPT, go to Settings > Voice and enable 'Background conversations' to continue talking even when the app is not in the foreground.
Start a voice chat From the microphone icon on the home screen, let the advanced voice load and check that it understands you correctly.
Set it as the default assistant: Settings > Apps > Choose default apps > Assistance & voice input, and select ChatGPT. If something fails, reinstall the app to force the setup.
Microsoft Copilot as an AI assistant: possibilities and limits
Microsoft Copilot beta lets you set it as your default assistant to invoke it with the same gestures as the Google Assistant and access its chatbot and image generation.
Install the beta on Google Play from the Copilot page by requesting access, or use APKMirror if you know what you're doing; you'll receive the test version in minutes.
Choose it as system assistant: Settings > Apps > Choose default apps > Digital assistant app > Device assistance and select Copilot.
How to summon: Use usual gestures (hold the power button, double-tap the button on some models, or swipe from the bottom corners); for now there is no 'Ok Copilot' as a wake-up word.
What it offers and its limits: Instant conversational responses and on-screen image generation; Android integration is weaker than Assistant or Gemini, so some system tasks (such as creating voice events) may not yet work.
Extra noteIf you live with Alexa at home, you can also use Alexa as an AI assistant on Android, although here we focus on Assistant, Gemini, ChatGPT, and Copilot.
Practical examples and everyday tricks
Reminders are one of the star uses of the assistant on mobile, especially for routines such as medication or daily obligations.
Example: With Google Assistant, say 'Ok Google, remind me to take my medication every day at 9 a.m.' and it will save it; to change it, 'Ok Google, change the medication reminder to 10 a.m.'; to delete it, 'Ok Google, remove the medication reminder.'
If you use iPhone at any time, you can say 'Hey Siri, remind me to take my medication every day at 9 a.m.' to create the reminder in Reminders.
In addition to reminders, assistants cover quick searches, dictating messages, opening apps, calling by contact name, and alarms. with natural phrases like 'Wake me up tomorrow at 7'.
Gemini adds benefits to chatting via text, voice, and images and can appear as an overlay when you say 'Hey Google' or activate it manually; if you want to switch between Assistant and Gemini, change it in Settings whenever you want.
If you turn off location, features such as weather and results for nearby places in both Search and the Google app will be affected.
Using the power button to invoke the AI ​​assistant is very convenient., and you can also have multiple wizards installed; only one will be the default, but nothing prevents you from opening the others whenever you want.
If you use Google services intensively, it's usually worth sticking with Gemini because of its integration with Google Maps, Gmail, and other apps, and because of Google's partnerships with brands like Samsung and OPPO that improve the experience.

For developers: Integrating AI into Android apps
If you develop apps, Google offers two great paths: on the device and in the cloud.Choosing the right one depends on privacy, latency, cost, and task complexity.
Gemini Nano enables on-device inference, with no per-use cost, enhanced privacy, and offline mode.; ideal for cases such as summarizing messages or text corrections where maintaining local data is a priority.
ML Kit Generative APIs (based on Gemini Nano) They give you production-ready solutions for summarize, correct and rewrite text y generate image descriptions, with a high-level interface.
If you need more open prompts on the device that go beyond the generative APIs of ML Kit, consider the experimental access to Gemini Nano (with limits of 1,024 tokens per message and 4,096 context tokens).
For traditional AA: ML Kit (OCR, barcodes, faces, image labeling, objects, language ID, smart responses) saves you from training models; MediaPipe gives you real-time pipelines for video/audio (hands, pose, facial mesh, segmentation); LiteRT (TensorFlow Lite runtime) runs your custom models with hardware acceleration.
If your app needs powerful multimodal capabilities in the cloud, use the Firebase AI Logic SDK to integrate Gemini Pro, Gemini Flash e Image with simple client calls and text, image, audio and video processing.
When to prefer traditional AA over generative AA: If your problem is classification, detection, or prediction based on existing patterns, classical techniques are usually more efficient and simpler to deploy, with lower computational costs.
How to decide between device and cloud: assesses seamless connectivity, privacy (local data), model complexity and size, cloud usage cost, device resources, fine-tuning needs, and cross-platform consistency (Android and iOS).
Quick Solutions Guide
- Generate content or edit text/images → Generative AI.
- Analyze and classify entries o real-time perception → Traditional AA (ML Kit / MediaPipe / LiteRT).
- Generative AI on the device With Gemini Nano: If it fits with your ML Kit GenAI tasks, use those APIs; if you need more open-source prompts, try experimental access to Nano. Keep in mind the token limits and device compatibility.
- Generative AI in the cloudIf you want quick integration and already use Firebase, the Logic SDK simplifies things. If you need maximum control, use the Gemini API with its own backend on Google Cloud to fine-tune models and scale on demand.
- You chose Firebase AI LogicFor balanced speed and cost, prioritize Gemini Flash; for quality and advanced reasoning, choose Gemini Pro; for imaginguse Image.
With all of the above, you now know how to activate Assistant or switch to Gemini from Google settings, make ChatGPT or Copilot your default assistant if you're looking for a different style, and when it's best to opt for on-device or cloud-based solutions if you're developing apps.
Whether you want to schedule voice reminders, dictate messages without looking at the screen, or integrate AI models into your next project, you have options for every need, can switch between them whenever it suits you, and take advantage of increasingly personal and capable mobile AI.
