Send the message you meant.
You have rewritten that text four times. Protexter lives in your keyboard and turns the rough version into something you can actually send, in Messages, WhatsApp, email and most apps you type in.
iPhone and iPad. No account. No API key to set up.
Free for 7 days or 100 AI actions, whichever comes first. No card needed. Then Pro, monthly or yearly. Cancel any time in Settings.
Most writing apps make you leave the conversation. Protexter is the keyboard. It is already there when the hard message arrives.
Fix
One tap cleans up spelling, grammar and punctuation and keeps your wording, tone and language.
Rewrite
Already typed something? Make it warmer, shorter, firmer, or more professional without losing your voice.
Ask AI
Say what you need, like running ten minutes late, and get a draft without leaving the chat.
The same draft, after one tap.
Three real shapes of message people get stuck on. Fix the typos or pick a tone, then edit anything before it sends.
You don't text your boss like your best friend.
Voices across work, family, dating, and everyday, plus custom ones you write yourself. Pin one to a specific contact and Protexter keeps them separate, so one conversation never bleeds into another.
It is a keyboard, so it goes with you.
Protexter is a custom keyboard rather than another app to open. It works anywhere iOS allows one, so the same rewrite is a tap away in whichever app the awkward message landed in.
It never reads your chats.
You choose what it sees
Protexter does not scrape your messages or monitor conversations. It only ever receives the text you hand it.
Cloud AI is off until you allow it
Third-party AI processing and conversation context are separate switches, both off by default. The keyboard sends none of your text to the cloud until you allow it, and conversation context never leaves your phone unless you turn it on.
Screenshots are read on your device
Paste a screenshot of a thread and the text is recognised locally. The image is never uploaded.
Sensitive details are redacted
By default, phone numbers, emails, links, and one-time codes are stripped from conversation context before it is sent.
Send me the 20 second setup guide
One short email with the two iOS steps most people miss when they add a keyboard, then a couple of follow-ups showing what Protexter can do. That is the whole series. Unsubscribe from any of them in one tap.

Before you download.
Does it work inside other apps?
Yes. Protexter is a custom keyboard, so it works anywhere iOS allows one: Messages, WhatsApp, Instagram, email, dating apps, and most text fields.
Can it fix my grammar and spelling?
Yes. Fix corrects spelling, grammar and punctuation in one tap and keeps your wording, tone and language.
Does it translate?
Yes. One tap switches a message between English and Brazilian Portuguese, keeping your tone. For other languages, ask AI from the keyboard.
Why does it need Full Access?
Full Access is the iOS switch that lets a keyboard use the network, and Protexter's cloud AI needs it. Third-party AI processing is a second switch in the app, off by default, and the keyboard sends none of your text to the cloud until you allow it. After that it sends the text you ask it to work on, and conversation context only if you turn that on.
Do I need an OpenAI or API key?
No. There is no account to create and no key to configure. Add the keyboard in Settings, open the app once, and allow the AI features when you want them.
Will it sound like me?
That is the point. You pick the voice, keep the facts you pin, and edit anything before it sends. Protexter never sends a message on your behalf.
