## What is AI Humanizer?

Paraphrase tool, AI email writer and grammar checker, built right into your keyboard. Reword any sentence, fix every typo and write emails in seconds.

GrammarFix is an AI keyboard that works inside every app: Messages, WhatsApp, Mail, Gmail, Instagram, Slack, Notes and more. Type as usual, tap a tool, and your text is fixed in place. No copying and pasting.

WRITING TOOLS ON YOUR KEYBOARD
• Proofread: fix grammar, spelling, punctuation and typos in one tap
• Rewrite: reword and paraphrase any sentence so it reads clearer
• Change Tone: make a message Friendly or Professional
• Concise & Expand: shorten long text or add helpful detail
• Summary & Key Points: summarize long messages and emails
• List & Table: turn messy notes into a clean list or table
• Translate: type and translate into English, Spanish, Portuguese, German, French, Italian, Dutch, Polish, Swedish, Turkish, Russian, Korean and Indonesian
• Describe your change: tell the AI how the text should sound and it rewrites it for you

IN YOUR LANGUAGE
The app and the keyboard come in 13 languages: English, Spanish, Portuguese, German, French, Italian, Dutch, Polish, Swedish, Turkish, Russian, Korean and Indonesian. Type on native layouts like AZERTY, QWERTZ, Korean and Russian, with regional versions for French, German, Spanish, Portuguese and Dutch.

WRITE BETTER EMAILS AND MESSAGES
Draft emails, replies, essays and posts faster. The AI writer keeps your meaning and your language, so it works for students, professionals and non-native English speakers alike.

PRIVATE BY DESIGN
Full Access is only used to power the writing tools. We never record or store your keystrokes.
