iPhone
Find better words without leaving the app you're typing in. Tap a word, open the keyboard, pick a sharper synonym.
Never get stuck on the right word again. This keyboard puts synonyms, antonyms, and clear definitions one tap away — inside any app, and fully offline.
WHY YOU'LL LOVE IT
• A real system keyboard — tap a word while you type to see synonyms and swap it inline, with no copy-paste and no app switching
• Synonyms, antonyms, part of speech, and a short definition for every word
• 100% offline and on-device — your typing never leaves your iPhone
• Smart word matching handles plurals and verb endings, so "running" still finds "run"
• Save favorite words and explore curated word collections to grow your vocabulary
• No account, no ads, no tracking
PERFECT FOR
Writers polishing a draft, students working on essays, and anyone building stronger English for IELTS, TOEFL, or everyday emails.
HOW IT WORKS
1. Enable the keyboard in iOS Settings > General > Keyboard > Keyboards
2. Tap the globe key to switch to it while writing in any app
3. Tap a word to reveal synonyms and pick a stronger one
The keyboard works without Full Access and never sends your keystrokes anywhere.
