Question 1

What is hi-key?

Accepted Answer

hi-key is an iOS keyboard that generates AI images from text prompts. You type a description of what you want to see, and hi-key creates 4 images in seconds — right inside any app you're already using.

Question 2

How does hi-key work?

Accepted Answer

Enable hi-key as a keyboard on your iPhone, switch to it in any app with a text field, type a description (e.g., "a cat wearing sunglasses on a beach"), and get 4 AI-generated images instantly. Tap any image to copy it to your clipboard.

Question 3

Which apps does hi-key work in?

Accepted Answer

hi-key works in any app that has a text input — iMessage, WhatsApp, Instagram DMs, Telegram, Slack, Notes, email, and more. It's a system keyboard, so it's available everywhere you type.

Question 4

Is hi-key free?

Accepted Answer

Yes, hi-key is free to download and comes with 5 credits to start. Each credit generates 4 images. Subscription plans start at $4.99/month for more credits, and one-time credit packs are available from $2.99.

Question 5

Is hi-key safe? Can it read my messages?

Accepted Answer

hi-key only processes the prompts you type in the hi-key prompt bar. It never reads, stores, or sends your messages, passwords, or any other content. Prompts are processed securely and not stored after image generation.

Question 6

What does the hi-key watermark mean?

Accepted Answer

Images generated on the free and lower-tier plans include a small "hi-key" watermark. If you received an image with this watermark, someone used hi-key to create it. The Super plan ($12.99/month) removes watermarks.

Question 7

How do I get more credits?

Accepted Answer

You can subscribe to a monthly plan (Starter, Plus, or Super) for recurring credits, buy one-time credit packs, or invite friends with your referral code — you both get 5 bonus credits.
