What StealthGPT does
StealthGPT is a humanizer tool. Positioned and marketed specifically around Turnitin's originality algorithm rather than general-purpose detectors.
Pricing: Plans from $14.99/mo; per-word bundles available for one-off use.
Bundled AI detector: No — pair with a standalone detector like GPTZero or Originality.ai
Strengths and weaknesses
What works
- Generates and rewrites in one pass, so you can skip a separate AI writer
- Aggressive sentence-level restructuring rather than word substitution
- No word cap on paid plans — good for full-length papers
What to watch for
- No free tier — you can't test quality before paying
- No bundled detector, so you need a second tool to verify results
- Output occasionally reads as overly formal for casual content
Our verdict
StealthGPT is best for: Long-form academic or research writing where sentence-level restructuring matters more than speed.
