Headcanon Generator
Generate fandom-neutral character ideas by genre and tone, with an optional name for more specific prompts.
Turn a prompt into character history
A useful headcanon creates a behavior and leaves room for a reason. Pick one result, ask when the habit began, decide who else knows, and connect it to a choice the character must make.
The generator avoids named franchises, so every prompt can be adapted to an existing favorite or an original world.
