AU means "alternate universe." It’s a version of a story where the characters stay the same but the setting changes, like a coffee shop AU or a royalty AU.

How do I use the AU generator?

Add your characters, pick an AU setting, optionally choose a tone, and hit generate. You’ll get a short premise that recasts your characters in that world, ready to write or roleplay.

What AU settings can I choose?

Coffee shop, soulmate, royalty, modern, high school, college, mafia, magic academy, superhero, apocalyptic, fantasy, pirate, hospital, and rockstar, plus a "Surprise Me" option that picks one for you.

Can I make an AU for just one character?

Yes. One character is enough, though AUs are often most fun with a pairing or a group so there’s a dynamic to play with.

Examples

Example AUs

The same two characters reimagined in two different worlds.

Coffee Shop AU

Characters: Ren & Della · Setting: Coffee Shop

Ren runs the quiet café on the corner that nobody important has discovered yet, which is exactly how he likes it. Della is the new regular who orders something impossible every morning and tips like she’s apologising for it. He’s started making her drink before she reaches the counter. She’s started arriving earlier than she needs to. Neither of them has said a word about it, and the café is very small.

Royalty AU

Characters: Ren & Della · Setting: Royalty

Ren is the second prince, the spare, free to be charming because nothing rests on him. Della is the envoy sent to negotiate a treaty her country can’t afford to lose. She was warned about the older brother. Nobody warned her about this one, the one who notices everything and pretends to notice nothing. The treaty has a deadline. So, it turns out, does pretending.

Working With AUs

What is an AU?

AU stands for "alternate universe": you take characters from a story and move them into a different setting while keeping who they are. The fun is in the contrast: a brooding warrior as a barista, sworn enemies as soulmates, a quiet character forced onto a stage. Same people, new world, new ways for them to collide.

Popular AU types

Some AU settings have become fandom staples because they reliably create chemistry:

Coffee shop: low-stakes, slow-building, full of small daily moments.
Soulmate: a built-in mark or tie that forces the question of fate.
Royalty: power, duty, and forbidden closeness.
Mafia: loyalty, danger, and trust that costs something.
High school / college: first feelings and second chances.

AU vs. a random scenario

An AU changes the world your characters live in; a scenario just drops them into a situation inside the world they already have. If you want a single tense or funny moment for your existing cast, the Random Scenario Generator is the tool. If you want to rebuild their whole setting, you’re in the right place.
