ChatGPT now refuses to write in the style of famous authors
ChatGPT has stopped imitating the distinctive voices of famous authors — living or dead — and the change is already affecting everyday users. Ask it to write a mystery in the style of Agatha Christie and it will decline, citing copyright protection. OpenAI hasn't announced the shift publicly, but independent tests by Ars Technica and Engadget have confirmed it's real.
The change
When Ars Technica asked ChatGPT to produce a detective story in Christie's voice, the chatbot said it couldn't closely imitate her distinctive style because her works are protected by copyright. It offered instead to write an original story with themes and atmosphere similar to classic crime fiction — without directly copying her approach.
Engadget ran the same test and got the same result. ChatGPT now draws a line between stylistic inspiration and direct imitation. It'll write something that feels like a classic whodunit; it won't write something that sounds like Christie wrote it.
This marks a clear shift. An earlier study by No Latency found ChatGPT could imitate deceased writers with little resistance. That's no longer the case — the refusal applies to both living and dead authors.
The legal play
The timing isn't accidental. OpenAI faces a string of US copyright lawsuits from outlets and authors — including claims from the New York Times, Sarah Silverman, and others — alleging the company trained its models on copyrighted material without permission. A $1.5 billion copyright ruling against rival Anthropic preceded this policy change, per Fast Company.
US copyright law doesn't protect style itself — only specific expression. But a chatbot that produces text indistinguishable from a named author's work risks crossing into what courts call "substantially similar" infringement. Mac Observer puts it plainly: a perfect copy on command looks very bad in front of a judge.
Blocking direct style requests lets OpenAI argue its tools inspire creativity rather than reproduce it — a meaningful distinction in litigation.
What you can still do
ChatGPT hasn't become less useful for creative writing. It will still generate fiction with similar themes, moods, sentence rhythms, or structural techniques — just without branding the output as a clone of a specific person's voice. For most users, that's probably enough. For power users who relied on precise author-voice simulation, the workaround is descriptive rather than name-based: ask for "terse, third-person sentences with understated emotion" instead of "write like Hemingway."
