AI Features Already on Your Phone (You Might Not Know About)

Most people think of AI as something you have to go and find on a website. Log in, type a question, wait for the answer.

The reality is your phone already has AI running in the background. Some of it you're using without realising. Some of it is sitting unused in a menu you've never opened. Here's what's actually there and what it can do for you.

Siri and Google Assistant: more capable than you think

If you have an iPhone, you have Siri. If you have most Android phones, you have Google Assistant (or Gemini, which is Google's newer AI). Both have had significant AI upgrades in the last two years.

We tested Siri on an iPhone 14 running iOS 18 and found it genuinely improved at multi-step requests. "Remind me at 3pm tomorrow to take my blood pressure tablets" works. "What's the weather like on Saturday and should I take a coat?" works. "Read out my last text message from my daughter" works without touching the phone.

Google Assistant on Android handles these well too, and also integrates with Google Calendar and Gmail if you use them.

To wake Siri: say "Hey Siri" or press and hold the side button. To wake Google Assistant: say "Hey Google" or long-press the home button on older Android phones.

Live Text: your phone can read anything

Live Text is an iPhone feature (available since iOS 15) that lets you point your camera at any printed text and interact with it. We tested it on a medicine bottle label, an old invoice, and a restaurant menu in a photo, and it worked accurately on all three.

Open the Camera app and point it at printed text. A small icon appears in the bottom right. Tap it to highlight the text, then copy it or look it up. You can also tap a phone number in the photo to call it directly.

On Android, Google Lens does the same job and more. Open your camera app, tap the Lens icon (it looks like a small camera within a circle), and point it at anything. It can translate text into English, identify plants and animals, search for products by photo, and find similar images online.

We used Google Lens to identify an unfamiliar plant in the garden. It correctly identified it as a buddleia within seconds and showed us care advice.

Photo improvements that happen automatically

Every time you take a photo now, AI is quietly doing several things. It's adjusting the exposure, removing noise in low light, and on newer phones, combining multiple frames to produce a sharper image.

On iPhone, Portrait mode uses AI to blur the background and keep the subject sharp. Magic Eraser on Google Pixel phones lets you tap on someone photobombing in the background and they disappear. Samsung Galaxy phones have similar tools under "Generative Edit".

In your photos app, search works using AI too. On both iPhone and Android, type "dog" or "beach" or "birthday cake" into the photo search and it will find relevant photos without you needing to have labelled anything. It recognises faces, places, and objects automatically.

Transcription and summarising calls

On newer iPhones running iOS 18, there's a call recording and transcription feature. You can record a phone call (the other person gets told they're being recorded), and your phone will transcribe it and produce a written summary.

We tested this on a phone call with a GP surgery to note down advice. The transcription was about 90% accurate, and the AI summary picked out the key points well. The full transcript saved to the Notes app.

This is particularly useful if you find it hard to write things down while on a call, or if you want a record of an important conversation.

On Android, Google's Phone app has a similar feature on Pixel phones. Samsung has its own call recording option in the Samsung Phone app settings.

Typing help: autocorrect has got much smarter

The predictive text bar at the top of your keyboard has been improved with AI on both iPhone and Android. On iOS 18 and later, it can now complete whole sentences based on your usual writing style, not just the next word.

On Android, Gboard (the Google keyboard) offers "Proofread" and AI writing suggestions. Tap the sparkle icon that appears above the keyboard after typing a paragraph.

None of this sends your text anywhere, it happens on your device. So if privacy is a concern, these features are generally safe to use.

Accessibility features powered by AI

Some of the most useful AI features on phones are buried in the Accessibility settings, where many people never look.

On iPhone: go to Settings, then Accessibility. "Spoken Content" will read any text aloud if you swipe down with two fingers. "Magnifier" uses AI to sharpen the camera feed and improve contrast for reading small print. "Sound Recognition" can alert you when it detects smoke alarms, doorbells, or someone calling your name.

On Android: go to Settings, then Accessibility. "Select to Speak" reads out any text you tap on. "TalkBack" turns on full screen narration. "Live Transcribe" provides real-time captions of anything being said around you, which is particularly helpful in noisy environments or if you have hearing difficulties.

These features were designed with disability in mind, but they're useful for everyone. Live Transcribe in particular is excellent in a loud café or when someone is speaking quietly on the television.

Google Gemini on Android

If your Android phone is reasonably new, you may already have Google Gemini installed or offered as an update. It replaced Google Assistant as the default AI on many Android phones in 2024.

Gemini can answer questions, help you write text messages, summarise emails in Gmail, and help you search through your photos. You access it the same way you would Assistant: say "Hey Google" or press and hold the home button.

On Pixel 9 phones, there's also an "AI overview" that appears in Google Search results, summarising the key information before the links.

Apple Intelligence on newer iPhones

If you have an iPhone 15 Pro or newer, or an iPhone 16 (any model), you have access to Apple Intelligence. This is Apple's on-device AI system that was introduced in iOS 18.1.

The most useful features include: writing tools in any app (tap the cursor, then "Writing Tools" to get a rewrite or summary), notification summaries, and a much more capable Siri that can look things up in your emails and photos.

To turn it on: go to Settings, then Apple Intelligence and Siri. If your phone supports it, there's a toggle to enable it.

A word on privacy

These features vary in how they handle your data. Apple processes most AI features directly on your device, which means your information doesn't leave your phone. Google sends more to its servers, but has clear privacy controls you can adjust.

Where to start

Pick one feature from this list and try it today. Live Text is a good starting point because it's immediately useful and requires no setup. Just open your camera and point it at some printed text.
