GhostWriter AI vs Humanizer.pro
Humanizer.pro and GhostWriter AI both convert AI-written text into human-sounding content. Here is what sets GhostWriter AI apart for users who want a free start, better detection results, or more flexible pricing.
More modes, deeper rewriting
GhostWriter AI uses Claude, one of the most capable large language models, with prompts that explicitly target burstiness and perplexity — the two metrics AI detectors actually score. This produces outputs that differ structurally from the original, not just lexically.
