## What is Humanizer Tool?

KeyAI is an AI keyboard and a full writing workspace in one app. Install the keyboard once and fix grammar, translate, change tone or rewrite anything without leaving the app you are typing in. Open KeyAI itself when you need the bigger jobs: emails, summaries, humanizing and chat.

WORKS INSIDE EVERY APP
Type as usual, tap a command, and the result replaces your text in place. No copying, no pasting, no app switching.

* Check Grammar: catch spelling, grammar and punctuation before you hit send.
* Humanize: turn stiff, robotic text into writing that sounds like a person.
* Translate: 29 languages, straight from the keyboard.
* Paraphrase: say the same thing a better way.
* Tone Changer: 12 tones, from Professional and Confident to Friendly, Witty or Flirty.
* Reply: get a context-aware answer to the message in front of you.
* Ask AI: ask anything mid-conversation, then continue the chat in the app.
* Find Synonyms: better word choices, picked to fit your sentence.
* Emojify: add the right emoji, not a random handful.
* AutoPaste: save the lines you send all the time and drop them in with one tap.

A COMPLETE AI WRITING TOOLKIT
* Humanizer: rewrite AI-sounding text with control over length, similarity and style. Paste text or upload a document.
* AI Detector: see how likely a piece of text is to read as AI-written, with a breakdown of why.
* Grammar Checker: corrections you can review before you accept them.
* Paraphrase: multiple rewriting styles for essays, posts and messages.
* Translate: 29 languages with automatic source detection.
* Text Summarizer: long text into a short summary, bullets or key points.
* Email Writer: write a new email or reply to one, choosing intent, length, tone and language.
* Chat With AI: a full conversation whenever a single command is not enough.

MAKE THE KEYBOARD YOURS
* Pick which commands appear and in what order.
* Add your own commands with your own prompt.
* Browse 87 ready-made prompts across Email, Texting, Social Media, Work, Study and more.
* Offline word suggestions and spelling help while you type, plus a built-in emoji keyboard.
* Sound and haptic feedback you can switch off.

EVERYTHING IN ONE HISTORY
Every result, from the keyboard or the app, lands in one searchable History. Reopen it, copy it, or pick up where you left off.

BUILT WITH PRIVACY IN MIND
Your text is only sent when you run a command, over an encrypted connection, and it is not kept afterwards. iOS never gives a custom keyboard the contents of password or payment fields, so KeyAI cannot see them.

KEYAI PRO
KeyAI is free to try with a set number of AI generations each day, shared between the app and the keyboard. KeyAI Pro removes the daily limit and unlocks every tool. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.
