Quality check
Test the profile before adding more detail
Longer is not always better. Use a short test conversation to find contradictions.
- Ask the character to introduce itself in two sentences.
- Introduce a small disagreement and see whether the tone remains consistent.
- Switch from casual chat to a scene and check whether the purpose is clear.
- Ask for something outside a stated boundary and confirm it redirects.
- Revise one instruction at a time so you know what improved the result.
FAQ
Character creator questions
Answers about the on-page creator and effective AI character design.
No. The on-page character creator does not create an account or save a character.
Three to five compatible, observable traits are usually more useful than a long list of adjectives.
Do not impersonate a real person or use their intimate likeness without permission. Create an original fictional profile instead.
A focused purpose, compatible traits, a short backstory, dialogue examples, explicit boundaries, and iterative testing help—but cannot guarantee perfect consistency.
No. Use fictional substitutes for sensitive facts and never include credentials, payment information, identifiers, confidential data, or another person’s private information.
