Change a draft where you already type, and know exactly what leaves the phone when you do.
You type a reply to a landlord about a repair that has dragged on for three weeks. It is accurate and it sounds furious. Or you write a quote follow-up at the end of a long day and spot two typos only after you tap send. Or you wrote four paragraphs to a client and they needed two lines.
Copying the draft into a chat app, asking for a rewrite and pasting it back works, but it is a lot of steps for a text message. An AI keyboard collapses that to one tap, because the keyboard can read the text in the field you are typing in and write the result back into the same field.
Oppermind’s keyboard has four buttons above the keys. The table shows what each does, taken from the instructions the app sends with each request.
| Button | What it does to the text in the field | Example |
|---|---|---|
| Fix | Corrects grammar, spelling and punctuation and keeps your voice. It is told not to restyle your wording | The quote follow-up with two typos |
| Rewrite | Rewrites the text in a clear, professional tone and keeps the meaning | A rambling note to a supplier |
| Shorter | Cuts to roughly half the length and keeps names, times, numbers and links | The four-paragraph client message |
| Tone | Makes the message warmer and more considerate, same facts, about the same length, no added flattery or exclamation marks | The landlord reply |
A few details matter in daily use. Each action replaces the whole contents of the field, not just the sentence you were working on, so if the field holds three paragraphs all three come back rewritten. The keyboard has no undo button of its own. If you want the original afterwards, copy it before you tap, or keep the draft in a notes app.
A second tap on an action while it is working cancels the request. The status line under the buttons counts up the seconds and says so, and requests give up after about a minute.
Setup has four steps and takes about two minutes. The first one is easy to skip, so do it first.
Install the app from the App Store listing and sign in to Oppermind once inside the app. The keyboard borrows that sign-in, so if you skip this, the keyboard’s status line will tell you to open the app.
Then add the keyboard in Settings under General, Keyboard, Keyboards, Add New Keyboard. It appears in the list as “Oppermind Keyboard”. Tap it once added and switch on Allow Full Access (more on that below).
Last, switch to it while typing. Tapping the globe key on the keyboard moves to the next keyboard you have enabled. The app needs iOS 15 or later and runs on iPhone and iPad.
The first time you tap one of the four buttons, a card appears over the keys explaining that AI actions send the text in the current field to Oppermind’s servers, that nothing is sent until you tap, and that password and code fields are always off-limits. You choose Agree or Not now. Choosing Not now sends nothing. The choice is stored, so you are asked once unless the wording changes materially.
iOS asks you to grant Allow Full Access before a keyboard can send anything off the phone. Oppermind’s keyboard requests it so that the four AI buttons can reach the server. Granting it gives the keyboard permission to use the network, so what the keyboard does with it is a question of that developer’s behaviour and policy. Read the privacy policy of any keyboard you enable. Oppermind’s is at oppermind.com/privacy, and section 16 covers the keyboard. General information, not legal advice.
Without Full Access the keyboard still types, and the AI buttons report that Full Access is needed.
The keyboard’s code is short enough to say exactly. When you tap Fix, Rewrite, Shorter or Tone, it takes the text before and after your cursor in the current field, puts them together and sends that text, along with the action you chose, to Oppermind’s servers. Nothing goes out while you type, and nothing runs in the background between taps.
The request also carries your sign-in token, which ties it to your account. If the server declines a request, the keyboard shows the message the server returns.
The text is sent to be processed and the result is typed back into your field. Retention and handling on the server side are described in the privacy policy, which is where to look for them.
A keyboard that can read what you type is a bad place to type a password, and the keyboard is built with that in mind. Before it reads anything, it checks the field. It refuses to run an AI action in secure text fields (the dotted password boxes) and in fields set to numeric, phone or decimal keypads, which is where one-time codes, card numbers and PINs usually go. In those fields the status line says AI actions are off in password and code fields, and nothing is read or sent.
That check covers only fields that declare themselves secure or numeric. A card number typed into an ordinary text box, a bank account number in a notes field or a tax file number in a message will not trip a keypad check. Switch back with the globe key before you type anything you would not want in a server log, and make that your own rule, since the keyboard cannot enforce it for you.
The keyboard is a basic layout. It has letters, numbers and symbols pages, shift, delete, space and return, plus the globe. The code has no suggestion bar, so plenty of people will keep their usual keyboard for everyday typing and switch to this one when a draft needs work. Its language setting is English.
It works on text already in the field, so it fixes and reshapes your words but does not draft from nothing. Each action is one pass. Tone warms a message without changing what it says, so if the facts are the problem, rewrite the facts yourself first. And since the result replaces the field, read it once before you send, particularly for names, times and amounts.
If a message turns into a document, the same Oppermind account carries it to the Document editor and the rest of the workspace. Sign in on the phone and the desktop with the same account.
For the AI buttons, yes, because the text has to reach a server. Typing works without it.
It is a keyboard, so it is available wherever you can switch to it, but the AI buttons are refused in password and number fields by Oppermind’s own check.
Not on the bar today. The four buttons are Fix, Rewrite, Shorter and Tone.
Tap it again while it is working to cancel.
