What should my caption be? Said every freaking person before posting their picture to Instagram. There's nothing worse than pondering that question for hours when you have a straight fire selfie that is destined for at least 100+ likes, yet your caption is still tbd.

CapGenius is the first and greatest way to search for all types of content directly in your keyboard.

Food puns, the driest sarcasm, movie quotes, music lyrics, motivational thoughts, and pick-up lines plus so much more are now all at your fingertips. Here's the best part- you don't have to leave whatever app you are using in order to look this crap up. Instagram, iMessage, Snapchat, emails, dating apps or wherever else you use a keyboard- CONGRATS! You are now funny, witty, creative and ready to take the world by storm.

Use the CapGenius search engine directly in your keyboard. It's like so easy that you're dumb if you don't use it.

Let's face it, captions matter. So do pick up lines, especially when you're on Bumble and Tinder trying to rebound from an ex that always said, "I'm not like the others." The infamous words of every wolf dressed in sheep's clothes.

Whether your texting your crush, emailing a client with something funny so they'll finally respond to you, roasting a friend in your group chat, or trying to make your shameless scandalous selfie break the internet- use CapGenius to make sure you actually look cool and hilarious.

After downloading CapGenius from the App Store prepare to have your life changed forever. Follow theses easy steps to start using the keyboard:

Launch the “settings” application
Choose “General”
Scroll down to “Keyboard”
Select “Keyboards”
Choose “Add New Keyboard”
Add “CapGenius”

Start using the keyboard and never have to ask yourself “What Should My Caption Be?” ever again!

So much fun!

I am a grandmother and not too tech savvy but I followed directions and had the app downloaded to my keyboard and use it all the time! I don’t post things very often but I use it all the time when texting back and forth with family and friends! It’s been a blast and as easy as using an emoji only funnier!! You can add your own too, how fun would that be for them to add one of your quips to their hysterical arsenal? Love capgenius!

Great app

The other poorly rated reviews just don't know how to follow instructions. After you actually follow the instructions, you then should have it on your keyboard and no longer need to open the actual app. Click on the globe button on the bottom of your keyboard and then slide to cap genius and it gives you so many different categories to choose from for captions! Great app!

I absolutely love CapGenius. Not only is its content humorous and witty but the text keyboard is sleek and incredibly easy to use. I highly recommend downloading this app if you want to take your captioning abilities to the next level! I have friends of all ages who love using CapGenius because it is so easy to install and use on the go.
