Is this headcanon generator free?

Yes. It’s free to use and doesn’t require an account.

What should I write as my character concept?

One sentence is enough: who they are, what they want, and what complicates it. Example: “A charming con artist who can’t lie to children.”

Can I keep results consistent with my canon?

Yes. Use Advanced options → Canon to paste any facts you don’t want contradicted.

What’s the difference between headcanons and a backstory?

Backstory explains the character’s history and motivations; headcanons add small, repeatable details (habits, preferences, dynamics) that show up in scenes.

How to Use the OC Headcanon Generator

Headcanons are the tiny, specific details that make a character memorable — the stuff that shows up naturally in scenes. This character headcanon generator helps you produce consistent, story-useful ideas without bloating your lore.

What you get

Headcanons: Category-tagged ideas you can paste into a character sheet
Notes: A quick vibe line, a contradiction, and a recurring motif

Tips for better headcanons

Write a concept with a clear role + vibe + friction.
Add canon constraints so the generator won’t contradict your world.
Specify categories if you want balance (habits/quirks/relationships/etc).
Keep the length short for punchy, usable ideas.
After generating, pick 3–5 favorites and make them recurring.
