I've been seeing more "AI-assisted" tags on AO3 lately.
Clicked into a few out of curiosity. Some felt off. Not badly written, just... the characters didn't feel right. Zhongli sounding too modern, Wanderer suddenly going soft, Harry and Draco talking like polite strangers.
I get why people use AI. It's quick, it's helpful. But something felt missing.
An Idea
I write fanfic too. I've used ChatGPT to brainstorm before. But every time it generates something, I end up rewriting most of it. Because AI doesn't really know these characters—it's just arranging words.
So I wondered: could I build an AI tool that actually understands characters?
Not the kind that spits out 800 words from a single prompt, but one that genuinely gets how Zhongli speaks, when Wanderer's walls come down, that specific tension between Harry and Draco where they clearly care but won't admit it.
How It Works
I spent a while organizing character data.
Each character has:
- Personality keywords: like Zhongli's "contracts," "erosion," "tea"
- Speech patterns: Zhongli references ancient wisdom, speaks slowly; Wanderer is sharp-tongued and sarcastic
- Relationship dynamics: the history and subtle emotions between characters
Then I built all of this into the prompts. The goal is to generate content that at least feels like "yeah, that's them."
What I Hope It Is
Not a "one-click generator," but a creative partner.
You have an idea but don't know how to develop it? It can help you think. You want to write a trope but worried about going OOC? It can give you a reference. You're stuck and need inspiration? It can brainstorm with you.
But the final product is still yours to shape. Because only you know what you're really trying to say.
About Character Consistency
I think the beauty of fanfic is "wild creativity within the bounds of who these characters are."
You can write Zhongli and Wanderer living together, fighting and making up, any AU you want. But if Zhongli suddenly becomes chatty or Wanderer turns into pure sunshine, they're not themselves anymore.
That's what I kept in mind building this. I'd rather generate less content than have the characters feel wrong.
Final Note
This site probably won't go viral, because it's not "convenient enough"—it still requires you to think and adjust.
But if you're the type who cares whether your characters feel in-character, I hope this helps.
If you use it and think it's useful, let me know what could be better. If you think "what is this even," that's fine too. Not every tool is for everyone.
That's all.
