What Is Undetectable AI?
Undetectable AI is an AI humanizer rewriting AI-generated text to read more naturally and evade AI detectors, achieving a reported 87% bypass rate against AI detectors at $9.99/month based on 2026 testing. Pricing uses a volume-based ladder: entry tier at $9.99/month (10,000 words, or $5/month equivalent with annual billing at $60 upfront), mid-tier at $19/month (50,000 words), and an agency-scale tier climbing past $80/month — the free trial is limited to just 250 words, and credits typically don't roll over month-to-month. Feature sets remain surprisingly consistent across paid tiers: humanization, writing-level matching, API compatibility, unlimited AI detection, and the Human Auto Typer.
A genuinely important honest caveat worth understanding: even at an 87% bypass rate, this means roughly 13% of humanized content is still flagged by AI detectors — this is a real, non-trivial residual detection risk rather than a guarantee, and anyone relying on this for high-stakes situations (academic submissions, professional contexts with real consequences for AI-content detection) should understand this genuine risk rather than assuming complete undetectability.
It's aimed at users wanting to reduce AI-detection flagging on generated content, with the important honest understanding that the reported 87% bypass rate leaves a genuine 13% residual detection risk — the very limited 250-word free trial provides minimal testing capability, so anyone evaluating the tool should budget for at least the $9.99/month entry tier to properly assess whether the humanization quality and bypass rate meet their specific needs.
