Because Sebastian is built for romantic companion chat, you will usually get more from the chat by giving one honest detail than by writing a long prompt. If the reply lands, keep going with specifics: what happened today, what you want the tone to be, or what you want Sebastian to remember next time.

That matters for searchers comparing AI characters because the best companion pages should tell you what the chat will feel like before you sign up: the rhythm, the likely use cases, and whether the character is built for comfort, chemistry, roleplay, support, or everyday conversation.
The fastest test is one real message. Start with a mood, a question, or a tiny scene, then let Sebastian carry the next beat.
