AI for grandparents: ChatGPT and Gemini on your phone, step by step

First: what is this?

ChatGPT and Gemini are assistants on your phone. You can type a question, say it aloud, or show a photo. They can answer in Ukrainian. You do not need to know how to code or use special words.

You only need one app to begin. Choose ChatGPT or Gemini. Both let you try the basics for free; you can skip an offer for a paid plan. Some features have limits.

Step 1. Download an app

Check your phone. If you normally use the Play Store, it is an Android phone. If you use the App Store, it is an iPhone. Tap a link in your row below to open the official app store.

1. On the app page, check the developer: OpenAI for ChatGPT and Google for Gemini. This helps you avoid a lookalike app from someone else.
2. Tap Install on Android or Get on iPhone. Wait until the button says Open, then tap Open.

Prefer not to install anything? Open chatgpt.com or gemini.google.com. You can get started there after signing in.

Step 2. Create an account or sign in

An account is your personal sign-in to the app. If you have used ChatGPT before or already have Gmail, try signing in before creating another account. Enter a password or verification code only on the app’s own sign-in screen.

How to sign up for ChatGPT

1. Open ChatGPT. Tap “Log in or sign up” or “Sign up”. The button name may vary.
2. If you already use Gmail on your phone, tap “Continue with Google”. Choose your account and follow the prompts. On iPhone, you can also choose “Continue with Apple” if you use your Apple ID.
3. If you choose email sign-up, enter an address you can access. Follow the app’s prompts: create a password if asked, and verify your email with a link or code if one arrives.
4. To verify, open Gmail or your email app, find the OpenAI message, tap its verification button or enter its code in ChatGPT. Then return to ChatGPT. Check Spam if the message is missing.

If you already have a ChatGPT account, tap “Log in” and use the same method as before: Google, Apple or email. You do not need a paid plan to ask your first question.

How to sign in to Gemini

1. Open Gemini. If you see a Sign in button, tap it. If you see a list of Google accounts, tap yours.
2. If you use Gmail, YouTube or the Play Store with your own profile, you probably already have a Google Account. Choose it and follow the prompts. You do not need a separate Gemini account.
3. If you do not have a Google Account, tap “Create account” on the sign-in screen and choose “For my personal use”. Enter your name and the details Google requests; choose a Gmail address or an existing email, create a password and complete any verification. Then return to Gemini and sign in with that account.

Cannot find the Create account button? Open Google’s sign-up page and follow the steps there.

If a sign-in code arrives, open your email and enter it in the app where you started signing in. Do not forward the code to anyone. You can skip an offer for a paid plan.

Step 3. Type your first question

1. Open ChatGPT or Gemini. At the bottom of the screen, find the message box. Tap it. The keyboard will appear.
2. Type: “I have potatoes, eggs and an onion. What can I make quickly? Explain one step at a time.”
3. Tap the send arrow beside your message. Wait for the reply. If it is confusing, type in the same chat: “Explain it even more simply.”

You can continue the conversation: “What if I have no eggs?” The assistant can refer to earlier messages in that chat, so you do not need to repeat everything.

Step 4. Ask aloud

In ChatGPT, find the voice conversation icon beside the message box and tap it. If asked, allow microphone access. Say: “Explain how to grow dill on a balcony. Speak slowly.” Wait for a reply. Tap the end button when you are done.

In Gemini, tap the microphone near the message box. Allow microphone access, say your question and, if the words appear in the box, tap the send arrow. Buttons may look slightly different on different versions.

If the microphone does not work, type instead. If the reply is too long, say or type: “Shorter. What should I do first?”

Step 5. Show a photo

1. Open a chat. Beside the message box, tap +, the paperclip or the camera icon. In ChatGPT it is usually +.
2. Choose Camera to take a new picture or Photos to select one on your phone. If asked, allow camera or photo access.
3. When the photo appears in your message, type: “Translate the writing on this seed packet into English.” Tap the send arrow.

If the writing is hard to see, place the item near a window, take a closer photo and try again. Google Translate is another app for live camera translation.

10 everyday ways to use an assistant

For each example, open ChatGPT or Gemini, say or type the sample question and tap send. Replace the words in brackets with your own details.

1. Cook with what you have

“I have buckwheat, an egg and an onion. Suggest a simple dinner. Give me one step at a time.”

2. Read a label or package

Attach a clear photo and ask: “What does this say? Translate it into simple English.”

3. Understand a phone button

“My phone is a [model]. How do I make the text bigger? Give me one tap at a time.”

4. Write a greeting to family

“Help me wish my grandchild a happy birthday. They are [age]. Write three warm sentences without a poem.”

5. Care for a plant or garden

Attach a photo of the leaves and ask: “What might be wrong with this plant? What should I check first?”

6. Make a shopping list

“Make a short shopping list for three simple dinners for two people. I already have [ingredients].”

7. Plan a trip

“What should I pack for a day trip to [city] in [month]? Make a simple list.” Check schedules and prices with the transport operator.

8. Make up a story for a grandchild

“Make up a short, cheerful bedtime story for a child aged [age] about a cat and a train.”

9. Understand a small problem at home

“The kitchen tap is dripping. What simple things can I safely check before calling a plumber?”

10. Check a suspicious message

“I received a message saying I must follow a link urgently or my account will be blocked. What are the warning signs of a scam and whom should I contact?” Do not open the link or share codes.

If something does not work

• No reply? Check your internet connection and try again.
• Cannot find the microphone or camera? Type your question instead. App updates can move buttons around.
• Confusing answer? Type: “Explain simply, without jargon, one step at a time.”

What not to share

Do not enter passwords, SMS codes, bank card numbers or photos of documents. An assistant can sound certain and still be wrong. Confirm medication and health questions with a doctor or pharmacist, and check schedules, addresses and prices with official sources.

The easiest start: install one app, ask about dinner and request one step at a time. Next time, try voice or a photo.
