AI Keyboard Features: Everything SmartType Can Do

What exactly is an "AI keyboard"? Here is a plain-English tour of every AI feature SmartType adds on top of normal typing.

An AI keyboard looks like a normal keyboard, but it can understand and rewrite your text on demand. Instead of only suggesting the next word, it can correct a whole sentence, translate it, change its tone, or write a reply for you — all in the app you are already using. Here is everything SmartType adds on top of fast, reliable typing.

Grammar correction

One tap rewrites your sentence with correct spelling, grammar, and punctuation — the kind of full-sentence fixes ordinary autocorrect cannot make. Great for professional messages and for anyone writing in a second language.

Real-time translation (369 languages)

Type in your language and send in theirs. SmartType translates your message into 369 languages without leaving the chat, so multilingual conversations stay in one place.

Smart replies

Reading a message you are not sure how to answer? SmartType can generate a natural reply based on the conversation, which you can send as-is or tweak. It saves time on the messages you would otherwise stare at.

Tone transformation

Turn a blunt line into something professional, friendly, or apologetic without rewriting it yourself. Useful for work email, customer messages, and defusing tense chats.

GPT chat and custom prompts

• ›Ask the built-in GPT chat a question and paste the answer without switching apps.
• ›Humanise stiff text or add natural idioms so it does not read like a robot.
• ›Save your own custom prompts for tasks you do often — your personal one-tap AI shortcuts.

Smarter everyday typing

• ›Next-word predictions with a custom words dictionary so it learns your vocabulary.
• ›Swipe/glide typing for fast one-handed input.
• ›Voice typing when you would rather speak than type.
• ›A full emoji keyboard with skin-tone options.
• ›Clipboard history so you can paste something you copied earlier.

Make it yours

SmartType is highly customizable: themes and colors, key sizing and layout, one-handed positioning, keypress sound, and haptic feedback — so the keyboard fits your hand and your style.

Private by design

Standard typing stays on your device, and text is only sent for processing when you actively trigger an AI action. SmartType is transparent about how your data is handled and does not sell it.

Free to start
