Pros & Cons

Undetectable AI

  • Reported 87% bypass rate against AI detectors, a real, tested performance figure
  • Consistent feature set (humanization, detection, API) across paid tiers avoids feature-gating confusion
  • Affordable annual pricing ($5/month equivalent) provides real value for sustained use
  • Genuine 13% residual detection risk even at the reported 87% bypass rate — not a guarantee
  • Free trial is limited to just 250 words, providing minimal testing capability
  • Credits typically don’t roll over month-to-month, requiring careful usage planning
