Spend less time typing the same messages. Flash Keyboard brings saved phrases, phrase packs and personal keyboard styles together, so your everyday replies are easier to reuse. SAVE YOUR EVERYDAY WORDS Create and edit phrases for greetings, work messages, customer replies or casual chats. Organize them into packs and insert saved text from the keyboard in apps that support third-party keyboards. MIX PACKS AND PICK A RANDOM PHRASE Combine selected packs into a collection, then draw a random phrase from the saved entries. Add variety to greetings and conversations without writing everything again. INSERT TEXT IN SECTIONS Split a phrase into sections and set the delay between them. Insert longer messages into the text field in a sequence that you choose. MAKE YOUR KEYBOARD YOUR OWN Choose keyboard themes and text styles. Add emoji and kaomoji to give your messages a personal touch. GET STARTED Create a phrase or choose a pack in the app, then follow the in-app guide to add the keyboard. Switch to Flash Keyboard when you want to use your saved content. Some apps and text fields may not support third-party keyboards. Start with a reply you use every day and build your own phrase collection.
