GPTZero and Originality.ai check whether word sequences are statistically likely to come from an AI model. They don't check whether the writing is any good. They can't tell you that "like blood from an open wound" is a cliché, or that dumping a character's age, hair, and outfit in paragraph two is something only AI does, or that narrating "How fitting" breaks the fourth wall.
Those are the patterns that make a reader, an agent, or an editor put your manuscript down. Those are the patterns Ghostproof catches. Here's what that looks like.
15 of the 23 fixes shown below. Each one targets a specific pattern that trained readers recognise as AI-written.
We tested the raw AI text and the Ghostproof-cleaned version against four independent AI detectors. Here's what happened:
Modest improvement. We're being honest about that. But here's why it doesn't matter:
AI detectors analyse statistical token probability. They measure whether word sequences are mathematically likely to have been generated by an AI model. They don't measure whether the writing is good, whether the similes are cliché, whether the narrator breaks the fourth wall, or whether the protagonist gets a full physical description in paragraph two like every AI character ever written.
Your readers aren't running your manuscript through GPTZero. They're reading it. And when they read "rain still dripping from her coat like blood from an open wound," they don't think "that's statistically improbable." They think "that's trying too hard." They think "this feels like AI."
Ghostproof doesn't try to fool detectors. It fixes the 265 patterns that fool readers. That's what the Seal certifies: not that a machine can't detect it, but that a human won't care how it was made.
