Fanfiction Community at War with AI – and Itself
A new fanworks movement has emerged to root out authors using generative AI, but detection methods are questionable and could trap innocent writers.
Readers are scrambling to detect AI-written fanworks, but their methods have yielded questionable results.
Disgust towards the use of tools like Claude, ChatGPT has long been prevalent in creative communities, including fanfiction. Tips for spotting AI-generated works have been shared, but a recent anonymous tool claims to identify code artifacts left behind by Anthropic’s Claude bot.
The tool highlights the code ‘font-claude-response-body’ in works suspected of using Claude, turning the background red on AO3 pages with the code.
The creator emphasizes the tool’s purpose is not to accuse users but to highlight the potential impact of AI on fanfiction communities.
