Understanding AI Creativity
The Headcanon Generator is your co-writer, not a replacement for your unique voice.
Subjective Interpretations
AI might interpret a character differently than your personal 'fanon'. Use it as a prompt, not a rule.
Specific Trivia Limits
The AI is great at psychology but may occasionally miss obscure trivia from a 20-year-old light novel. Always double-check facts.
The Human Touch
AI provides the spark, but the emotional 'soul' of your fanfic comes from your unique writing style.
