Character Scenario Generator
"How would they react if…?" Name your characters and a situation — or let the generator invent one — and get three scenario headcanons with each character's in-character reaction.
Name at least one character, then press Generate. Leave the situation blank to get three invented ones.
Making scenarios feel in character
A scenario is a stress test. Put a calm character in a crisis and you learn what calm costs them; put a loud one in a quiet moment and you learn what they're covering. When you read the results, check that each reaction couldn't be swapped to another character without changing it. If it could, add a canon detail to the situation box and run it again.
Once a scenario sticks, turn it into a full scene with the fanfic generator or a back-and-forth with the dialogue generator.

Questions writers ask
What is a scenario headcanon?
A scenario headcanon imagines how characters would react to one specific situation — "how they'd react to you falling asleep on them", "what they'd do on a rainy day off". It is one of the most-requested formats on Tumblr ask blogs and in x reader fandoms.
Can I use it for x reader / Y/N scenarios?
Yes. Put "Reader" or "Y/N" next to the character names and describe the situation from the reader's side. Each character's reaction is written in character, with a line of dialogue.
How many characters can I include?
Up to about five works well. Each named character gets their own reaction paragraph, so the contrast between them does the work.
Is there a random scenario option?
Tap one of the example situations, or leave the situation blank and pick a scenario type — the AI invents three situations of that kind for you.
