Long fics, series, and multi-chapter projects need consistency. A character bible—a doc of traits, habits, and dynamics—keeps your cast from drifting. The AI Headcanon Generator can help you build one without spending hours brainstorming from scratch.
Gather character details
Run each main character through the Character Headcanon Generator. Ask for habits, pet peeves, internal thoughts, or "reactions to small inconveniences." Save 5–10 per character that feel them. Put them in a doc with headings: Habits, Voice, Under Stress, Alone. You can access the generator from the homepage.
Add relationship notes
For key pairs—protagonist and love interest, protagonist and rival, found family—use the Relationship Headcanon Generator. Save micro-rituals, tensions, and "how they act around each other." When you write a scene between them, you'll have a reference instead of guessing. All four tools are one click away on the AI Headcanon Generator main page.
Fill gaps with random and quotes
Missing a detail? The Random Headcanon Generator can suggest "suspiciously specific" ideas. The Incorrect Quotes Generator helps you check if dialogue sounds like the character—paste a few into your bible as "voice samples." Both are linked from the homepage.
Your character bible doesn't need to be huge. Start with a handful of headcanons per character and a few per relationship. Visit the AI Headcanon Generator homepage, run the generators, and build your reference doc as you go.
