About Knack
Say it better — before you send.
Knack is your AI writing assistant for email, chat, and anywhere you type. Fix grammar, rephrase awkward sentences, adjust your tone, and reply faster — without leaving the app you're in.
Write with confidence
• Grammar & professional tone — polish emails and messages before you hit send
• Rephrase anywhere — custom keyboard, Share menu, or text selection in any app
• Smart replies & occasions — respond to emails, birthday wishes, and everyday messages in one tap
• Playful tones — flirty, teasing, and other fun modes when the moment fits
• US slang & rich vocabulary — sound natural or elevate your word choice
• History & review — revisit past rephrases and edit longer results before replacing text
Three ways to use Knack
1. Knack Keyboard — tap Improve, Grammar, or Pro and text is replaced in place
2. Rephrase with Knack — select text and choose Rephrase from the menu
