UndetectedGPT (formerly UndetectableGPT)
What is UndetectedGPT (formerly UndetectableGPT)?
UndetectedGPT humanizes AI-written text so it reads naturally and scores lower on detectors like GPTZero, Turnitin, and Originality.ai. You paste draft copy, pick a tone such as Academic, run Ghost Mode humanization, and check the result in the built-in AI Detector before you submit.
Generic paraphrasers swap words without targeting detector behavior. UndetectedGPT adds Ghost-1, a proprietary humanization model, plus Ghost Writer for longer edits in a document-style editor. Paid tiers raise daily credits, stealth boosts, and per-request word limits while the free plan stays capped at two credits and 150 words per run.
Students, marketers, and freelancers use UndetectedGPT when ChatGPT or Claude drafts need a more human rhythm without a full manual rewrite. The old undetectablegpt.com domain no longer resolves, so the product now lives at undetectedgpt.ai.
