The best AI keyboard for iPhone in 2026

An AI keyboard replaces your iPhone's system keyboard and adds a row of one‑tap actions that transform whatever you're typing — rewrite it, fix the grammar, make it shorter or longer, change the tone, or translate it — without leaving the app you're in. No copy‑pasting into ChatGPT, no switching back and forth.

If you write a lot on your phone — messages, emails, captions, replies — a good AI keyboard saves real time and makes everything read better.

What to look for

Works in every app. The whole point is that it works in Messages, Mail, WhatsApp, Slack, Instagram — anywhere there's a text field.
One‑tap actions. Rephrase, fix grammar, expand, shorten and translate should be a single tap on the action bar, not a menu dive.
Tone control. The same sentence can be formal, friendly or confident — you should be able to steer it.
Privacy. A keyboard sees a lot. Look for one that only reads text when you tap an action, never logs keystrokes, and doesn't store your messages.
Feels native. It should type as smoothly as Apple's keyboard, with the layouts and languages you use.

How Rewordo does it

Rewordo is an AI keyboard built around exactly these points:

Rewrite, fix, expand, shorten, translate — all one tap on the action bar, in any app.
Set a tone so every rewrite sounds like you meant it.
Custom commands — add your own instructions with a name and icon.
Private by design — your text is never stored, there's no account, and if you bring your own AI key it stays encrypted on your device.

You can start free with Rewordo's managed AI, or bring your own key for unlimited use. See the plans and pricing.

Rewordo is coming soon to the App Store — join the waitlist and we'll let you know the moment it launches.
