Have you ever liked a pairing in a fandom so much, you decided to write about them? Or read about other people writing about them? Well, that's essentially what fan fiction is, and it's always been about creativity, passion, and giving those beloved characters new stories beyond their original worlds. But now with AI on the rise, some authors are taking shortcuts—after all, why spend hours typing out your idea when you could just get an LLM to generate entire stories in seconds?
Yep, for some, AI is no longer just a helpful tool for brainstorming, editing, and overcoming writer's block. In fact, it's now taking over the originality and creativity that have defined the community for years. And as AI becomes more and more accessible and "intelligent," the disagreement raises larger questions about authorship and what readers actually want from fan-created works.
Why Fan Fiction Writers Are Divided Over AI
As we mentioned, fan fiction has traditionally been a space where people brainstorm and punch out their own stories because they love a particular fandom, character, or pairing too much. For decades—at least before the rise of AI—writers would spend hours developing plots, exploring relationships, and imagining scenarios that official creators never considered. There was enjoyment in the arduous process. There was love. With AI-generated works, though, is that love and enjoyment even reflected at all?
These concerns aren't limited to a handful of outspoken writers, either. Case in point: in a 2025 study that surveyed 157 fan fiction readers and writers about generative AI's growing presence, a whopping 92% agreed that fan fiction is a space reserved for human creativity. Another 84.7% doubted AI could ever reproduce the emotional depth of human-authored stories. Though the sample size was relatively small, the findings illustrate some of the emotions brewing in the community.
There's also something particularly personal about writing fan fiction that makes AI involvement controversial. Many authors use their favorite characters to explore complex relationships and experiences that matter to them, sometimes spending months or years perfecting a single story. When an entire story can be generated from just a short prompt, can that same creative connection even exist?
Can AI Actually Help Fan Fiction Writers?
And yet. Despite all the objections, not everyone believes AI should be excluded from fan fiction. At least, not entirely. After all, a case can be made for someone struggling to organize a complicated plot or string together different ideas for a scene, and an AI chatbot may be able to offer viable suggestions worth considering. Writers might also use it to identify inconsistencies, develop outlines, or even simply to proofread their work before it gets posted. Doesn't the author still make the important creative decisions?
Interestingly, attitudes toward AI often depend on how extensively it's used in a single piece. In the same 2025 research, it was found that 82.7% of surveyed participants were willing to read fan fiction that used AI—but only if it was solely used for spelling and grammar corrections. Writers, on the other hand, were considerably less supportive: they'd rather not have AI be involved in any part of the process, be it during initial drafts or during major rewrites. To some, just having AI touch any part of their work is enough to make it feel inauthentic.
For aspiring writers, of course, these tools might offer a more approachable start. Someone writing in a second language, for example, might appreciate the extra help in correcting awkward sentences or incorrect word choices. Others may simply benefit from getting feedback on what they've written, regardless of whether that advice comes from an LLM or not. As it turns out, the line is blurrier than you think.
Should AI-Generated Fan Fiction Be Allowed?
So, should AI-generated works be allowed? Well, take, for example, Archive of Our Own (AO3), one of the best-known fan fiction archives: they've maintained that AI-generated works aren't automatically prohibited, though users are encouraged to tag any AI-created works. Readers of the platform, of course, haven't taken this in good stride—most believe that not only should AI-generated works be tagged, but they shouldn't be posted at all. How would it feel to like a story, only to realize later that it wasn't written by a human?
Plus, there are also concerns about consent and originality. LLMs are fed tons and tons of data, and the only reason they "sound" human is that they were trained on human-written works. That fan fiction story you love that was written before the boom? Well, it could've been scraped by AI, which then helps produce the hundreds of thousands of "fan"-written pieces you see in the same community today.
Unfortunately, regardless of whether AI has a place in fan fiction, it certainly doesn't seem like readers or writers have a choice. And since no one can agree on where the line should be drawn, perhaps the best course of action is to just adapt—and, of course, preserve meaningful human creativity as much as we can.
