## What is Keylio?

Stop switching between apps just to translate a message or fix your grammar. Keylio is an AI-powered keyboard that translates, adjusts tone, fixes grammar, and generates  
  smart replies, right where you type. No copy-paste. No app switching.                                                                                                     
                                                                                                                                                                             
  TRANSLATE AS YOU TYPE
