The email to your professor, in one try.
You have opened that draft four times. Protexter rewrites it in your keyboard, in Mail or Messages, so the ask is clear and you sound like a person who has their act together.
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.
The message you keep not sending.
Rewrite what you already typed. Pick the tone, read it back, change anything before it sends.
You don't text your boss like your best friend.
Voices for coursework and email alongside the ones you use with friends and family. Pin a formal voice to your professors and keep your normal one for the group chat.
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.
Is this cheating on my coursework?
Protexter is built for messages, not assignments. It rewrites texts and emails you are already writing. Check your institution's policy before using any AI tool on graded work.
Can it check my grammar before I send an email?
Yes. Fix corrects spelling, grammar and punctuation in one tap and keeps your wording, tone and language, so the email still sounds like you. Read it once and send it.
Do I need an account or an 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.
Does it work in Mail and in the group chat?
Yes. It is a custom keyboard, so it works anywhere iOS allows one, including Mail, Messages, WhatsApp, Instagram, and most text fields.
Can it see my conversations?
No. Protexter does not read or scrape your messages. It only ever receives the text you hand it, and third-party AI processing is off until you turn it on.
