They&#8217;re characterization. A character who changes the subject when someone mentions their hometown is more interesting than one who will talk about anything.

That means the greeting, the definition, and, most importantly, real lines from your chats. Our <a href=\"https:\/\/www.redbean.ai\/blog\/export-character-ai-chats\">Character.AI backup guide<\/a> walks you through it.<\/p>\n<p>Then run your notes through this template. You&#8217;ll often find the character has drifted over hundreds of chats. Rebuilding is a chance to decide who they <em>really<\/em> are.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Putting_them_in_a_world_not_just_a_chat\"><\/span>Putting them in a world, not just a chat<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A great character sheet works in any app. But characters shine brightest when they have a place to live and other characters to bump into. Mira is fine on her own.
