GhostWriter AI vs StealthWriter
StealthWriter and GhostWriter AI both aim to make AI-generated content pass detection. Here is how they compare — and why GhostWriter AI may be the better fit for your needs.
Same goal, different approach to getting started
Both tools rewrite AI content to lower detection scores. GhostWriter AI emphasises two specific metrics that real detectors score: burstiness (sentence-length variation) and perplexity (word unpredictability). The Advanced mode adds a second pass — the model critiques its own output and removes the remaining AI tells.
