Say it the way you would if English came easy.
You know exactly what you mean. Turning it into polished English on a phone keyboard is the slow part. Protexter rewrites your draft in place, inside the app you are already typing in, and keeps your meaning intact.
iPhone and iPad. No account. No API key to set up.

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.
Informal in. Professional out.
Rewrite in place works on text you have already typed. Choose professional, shorter, warmer, or firmer, then edit anything before it sends.
You don't text your boss like your best friend.
Voices built for work, from plain and direct to diplomatic, alongside everyday and family ones. Pin the professional voice to your work contacts and the casual one to everyone else.
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.
Can it rewrite informal text into something more formal?
Yes. Rewrite in place takes text you have already typed and returns it in the tone you pick, including professional. You review the result and edit it before anything is sent.
Does it work if English is not my first language?
It is built for exactly that. You type the meaning however it comes out, and Protexter returns clear professional English that says the same thing.
Can it fix my grammar without rewriting the message?
Yes. Fix corrects spelling, grammar and punctuation in one tap and leaves your wording, tone and language as they are. Use Rewrite when you want it to sound more professional.
Can it translate a message I wrote in Portuguese?
Yes. Translate switches a message between Brazilian Portuguese and English in one tap and keeps your tone. For other languages, ask AI from the keyboard.
Does it work in email and Slack, not just Messages?
Yes. Protexter is a custom keyboard, so it works anywhere iOS allows one, including email, Slack, LinkedIn, and most text fields.
Will my employer's messages be uploaded somewhere?
Only the text you hand it. Protexter does not read or scrape your conversations. Third-party AI processing and conversation context are separate switches, both off by default, and by default links, emails, phone numbers, and one-time codes are redacted from conversation context before it is sent.
