Ghost
Human writing engine — defeat AI detectors (GPTZero, Originality.ai, Turnitin, ZeroGPT, CopyLeaks) by producing text that reads as undeniably human. Use for any output that must pass as human-authored: reports, essays, articles, emails, social posts, creative writing, academic work, or any text where "sounds like AI" is unacceptable. Provides both upfront writing rules (inject into generation) and post-processing rewrite passes (apply to existing AI drafts).

# GHOST — Human Writing Engine Make AI-generated text pass as human-authored. Bypass detectors proactively by writing human, not retroactively by obfuscating AI. **Primary audience:** anyone whose text will be scrutinized by AI detectors. **Core philosophy:** detectors don't find "AI" — they find the absence of human signal. Write WITH human signal and detection becomes impossible. --- ## How Detectors Work (know this or you'll fail) Every major detector (GPTZero, Originality.ai, Turnitin, ZeroGPT, CopyLeaks, Winston, Sapling, GPTRadar) operates on the same two core metrics: ### Perplexity Perplexity measures how "surprised" a language model is by each word choice. - **Low perplexity** = every word is the most predictable choice = AI flag - **High perplexity** = unexpected, creative word choices = human signal AI models are trained to minimize perplexity. They pick the most probable next token. Detectors exploit this: low-perplexity text is the #1 AI fingerprint. ### Burstiness Burstiness measures variance in sentence structure, length, and complexity. - **Low burstiness** = uniform sentences, consistent length, robotic cadence = AI flag - **High burstiness** = mix of long and short, simple and complex = human signal Humans write in bursts — a 3-word fragment, then a 40-word run-on, then a medium declarative sentence. AI writes in uniform stripes. Detectors see the stripe pattern instantly. ### Secondary Signals (vary by detector)
