The Lighthouse Key

A 60-second story with 4 endings

Midnight. The lighthouse across the bay has been dark for twenty years, until tonight. Its beam sweeps the water and stops on your window. On your desk, an old brass key you have never seen before begins to hum.

Questions, answered

Questions about the app, feedback on a story, press or partnership ideas: we read every message.

What is uStory?

uStory is an interactive story app. Instead of reading a story from start to finish, you make choices at key moments and the story continues down the path you picked. Many stories hide several different endings. You can also write and publish your own.

Is uStory free?

Downloading uStory and reading free stories costs nothing. Some stories are paid and unlock with uMoney, the in-app currency. Premium, which you can start with a free trial, removes ads and unlocks extras such as hidden branches and paid stories.

Do I need an account to read?

Yes, you need a free account to read. You can create one in seconds with your email, Apple or Google account, and your progress, library and purchases stay with you on every device.

How does AI story creation work?

You write the essentials: a title, an overview, the backstory, the first page and the first choices. When readers pick a path, AI continues the story inside the world and characters you built, so every choice can open a new branch.

What is Time Travel?

Picked the wrong door? Time Travel takes you back to an earlier choice so you can follow a different branch without starting over. It uses uMoney.

Can I use uStory in my language?

uStory is multilingual: you can set both the app's language and the language of the stories you read. Pick your preferred story language in the app settings.
