When to choose AIDetectPlus vs Post.ai (and when to walk away)

Choose AIDetectPlus if

  • L2 Architecture & Defensibility: Defensibility relies on combined classification and stylistic humanization pipelines, though low capital barriers and reliance on public transformer heuristics restrict long-term technical defensibility.
  • Commercial Model Fit: Your procurement budget aligns with Custom / enterprise pricing.

Walk away from AIDetectPlus if

  • Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (AIDetectPlus requires sales-gated custom quoting).
  • Walk away if your workflow cannot tolerate false positive drift: Heuristic perplexity scoring produces high false-positive rates on technical documentation, structured legal briefs, and standardized corporate whitepapers.
  • Walk away if semantic degradation is a deal-breaker for your team: The automated humanization module frequently strips precise technical jargon, introducing factual distortion during aggressive synonym substitutions.
