About Story Builder
Free online Mad-Libs-style fill-in-the-blanks game. Shout out nouns, verbs, and names without seeing the story, then watch the hilarious result read back word by word. AI writes fresh story templates on any theme.
Story Builder is the classic Mad-Libs-style word game with no book to buy and no blanks to pencil in. The app keeps the story secret while it collects words from the group - nouns, verbs, names, silly sounds - then reveals the finished story word by word so the punchlines land one at a time. It ships with 13 built-in story templates, so it works instantly with no setup. The AI is what keeps it endless: type any topic - a camping trip, dinosaurs, your kid's birthday party - choose an age group and difficulty, and it writes a brand-new template with 6-9 blanks in seconds, funny precisely because your group's random words land in it. Brilliant for family game night, classrooms practising parts of speech, sleepovers, and long car rides - and for video calls: one person holds the page and collects words from everyone in the call, then performs the finished story for the family.
Frequently asked questions
How do you play Story Builder?＋
The app picks a story but keeps it hidden. It asks the group for one word at a time - an adjective, an animal, a place - and everyone shouts suggestions. Once all the blanks are filled, the story is revealed word by word with your answers inside, and someone reads it aloud.
Can the AI write a story about any topic?＋
Yes - type any theme into the topic box (space camp, a cooking disaster, your pet) and the AI writes a brand-new fill-in-the-blanks template about it. Pick an age group from young kids to adults so the vocabulary and humour fit your players.
Is it good for kids learning grammar?＋
Yes - it's a sneaky grammar lesson. Each blank asks for a part of speech (noun, verb ending in -ing, adjective), so kids practise the concepts while trying to make the story as silly as possible. Teachers use Mad-Libs-style games for exactly this.
How many people can play?＋
One player can fill the blanks solo, but it's funniest with a group of 2 or more shouting suggestions while one person types. Pass the phone around or plug into a TV for parties.
What if the AI is unavailable?＋
The game always works: 13 built-in story templates are included, and you can replay any of them with new words for a completely different result - no AI required.
Can we play with family on a video call?＋
Yes - it needs only voices. One person keeps the page open and asks the call for each word ('give me an animal!', 'a silly name!'), then reads the finished story aloud. Grandparents love this one, and the AI can write the template about your own family in your own language.
