How to Create a Genmoji on iPhone: What You Need to Know
Genmoji is one of the more genuinely fun features Apple introduced with Apple Intelligence — the company's on-device AI system. It lets you generate a custom emoji from a text description, right inside the emoji keyboard. Want a capybara wearing sunglasses riding a skateboard? Type it. Genmoji will attempt to render it.
Here's how the feature works, what it requires, and the variables that determine how useful it ends up being for you.
What Is Genmoji?
Genmoji are AI-generated emoji images created from natural language prompts. Unlike standard emoji, which are fixed Unicode characters, Genmoji are unique image files produced on demand by a generative AI model running on your device.
They can be used in Messages, shared as stickers, or added to Tapbacks — the quick reactions you send to individual messages. You can also create a Genmoji based on someone's likeness using a photo from your library, making it possible to turn a friend's face into a custom emoji character. 🎨
What You Need Before You Start
Genmoji is not available on every iPhone. It requires:
- iPhone 16, 16 Plus, 16 Pro, or 16 Pro Max — or an iPhone 15 Pro / 15 Pro Max
- iOS 18.2 or later (Genmoji wasn't available at the iOS 18.0 launch; it arrived with the 18.2 update)
- Apple Intelligence enabled on your device
- Your device language and Siri language set to English (United States) — though Apple has been expanding language support over time
If you're on an older iPhone or haven't updated past iOS 18.1, Genmoji simply won't appear as an option. Apple Intelligence itself requires the A17 Pro chip (iPhone 15 Pro) or the A18 / A18 Pro chip (iPhone 16 series) to run the on-device AI models.
How to Create a Genmoji: Step by Step
Step 1 — Open a Messages Conversation
Genmoji creation currently lives inside the Messages app. Open any conversation and tap the text input field to bring up the keyboard.
Step 2 — Open the Emoji Keyboard
Tap the emoji icon (the smiley face) in the bottom-left corner of the keyboard to switch to the emoji picker.
Step 3 — Find the Genmoji Option
Look for a sparkle icon or a dedicated Genmoji button within the emoji keyboard. In iOS 18.2+, this appears as a distinct option — usually at the far right of the emoji category bar or as a prominent button near the search field.
Step 4 — Describe Your Emoji
A text prompt field will appear. Type a description of what you want — be specific. Something like "a sleepy sloth holding a coffee cup" will produce more focused results than just "sloth." The model responds better to adjectives, context, and mood descriptors.
Step 5 — Generate and Select
Tap Generate. The system will produce several variations. Swipe through the options, preview them, and tap the one you want to use or save. You can regenerate if none of the results land right.
Step 6 — Send or Save
Tap a Genmoji to send it immediately in your conversation, or press and hold to save it as a sticker to your sticker library, where it becomes accessible across apps that support stickers.
Creating a Genmoji from a Photo
To base a Genmoji on a person's face:
- Tap the person icon or look for the option to add a photo reference inside the Genmoji interface
- Select a photo from your Photos library
- Add a description to modify or style the result (e.g., "as an astronaut" or "in watercolor style")
The AI uses facial features from the image as a reference point, then renders a stylized version in emoji form — not a photorealistic image.
Factors That Shape Your Results
Not every Genmoji experience looks the same. Several variables affect what you get: 🔍
| Variable | Effect on Output |
|---|---|
| Prompt specificity | Vague prompts produce generic results; detailed prompts produce more targeted ones |
| Device model | iPhone 16 Pro processes faster; all compatible devices use the same model tier |
| iOS version | Later updates have refined the image quality and expanded generation options |
| Photo quality | Low-resolution or cluttered reference photos produce less accurate face-based Genmoji |
| Content filters | Apple's on-device filters will decline prompts that conflict with content policies |
What Genmoji Can and Can't Do
Genmoji are image files, not Unicode characters. That means they don't render as standard emoji for recipients outside Apple's ecosystem — if you send a Genmoji to an Android user via SMS, it typically arrives as a static image attachment or may not display at all. Inside iMessage between Apple devices, they work cleanly.
They're also not infinitely scalable in the way vector emoji are — they're AI-generated raster images, so quality at very large sizes may vary.
The Part That Depends on You
How useful Genmoji turns out to be comes down to specifics no one else can determine for you: whether your device and iOS version actually support it, how central Messages is to how you communicate, and whether the people you're sending to are also on Apple devices. Someone deep in the Apple ecosystem who lives in iMessage will find very different value here than someone who splits time between platforms or uses third-party messaging apps as their primary tool.
The feature works as described — but whether it fits naturally into the way you actually communicate is something only your own setup and habits can answer.
