GhostPen

GhostPen is a web-based tool that rewrites AI-generated text so it passes as human-written. It targets popular AI detectors like Turnitin, GPTZero, and Originality.ai. You paste text from ChatGPT, Claude, or Gemini, click a button, and get a version that reads naturally but avoids detection flags. The tool offers different modes for academic, media, and general writing.

The core of GhostPen is a hybrid engine that combines DeepSeek R1 and Claude 3.5. DeepSeek handles the logical structure and anti-detection layout, while Claude refines the language to sound natural. The company says it keeps no logs — all submitted text is deleted after processing. There is also a 7-day money-back guarantee and direct developer support. The interface is simple: paste text, choose a mode, and hit the humanize button.

GhostPen is built for students who need to submit AI-assisted essays without triggering Turnitin, freelance writers whose clients require passing Originality.ai checks, and SEO specialists who want to publish AI-generated content that ranks well. Pricing starts with a free trial (1,000 words), then one-time packs from $4.90 (10,000 words) to $23.99 (150,000 words), with no expiration on word credits.
