Undetectable.ai

Undetectable.ai is an AI text humanizer that rewrites AI-generated content to evade detection tools.

Our take: Undetectable.ai is primarily a humanizer/rewriter: you paste AI-generated text and it reworks phrasing, sentence structure, and vocabulary so the output reads as human-written and passes major detectors (GPTZero, Turnitin, Originality.ai).

What it really isUndetectable.ai — AI text humanizer that rewrites AI-generated content to evade detection tools.
Our takeUndetectable.ai is primarily a humanizer/rewriter: you paste AI-generated text and it reworks phrasing, sentence structure, and vocabulary so the output reads as human-written and passes major detectors (GPTZero, Turnitin, Originality.ai).
The entry price is $9.99/mo for 10K words, with annual plans cutting that to $5/mo. The product also bundles unlimited AI detection scans, making it a useful two-in-one for anyone managing AI-assisted content at scale.
Why we rate itUndetectable.ai keeps pricing honest and simple — word-bucket tiers with deep annual discounts, a real refund guarantee, and API access on every plan.
The unlimited scan bundling means you are not paying twice to detect and then humanize.
The catchWord quotas reset monthly, so bursty workflows can hit limits fast; the free trial (250 words) is too small for meaningful evaluation, and the tool cannot guarantee brand voice consistency without manual editing.

Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: paste text, click humanize, get output in seconds — no setup or onboarding required.
  2. Scale breakpoint
    Monthly word caps create friction at scale; 35K words/mo is the highest self-serve tier before needing a custom enterprise plan.
  3. Walled garden
    Low: no proprietary file formats; output is plain text you can copy anywhere. API access is included on all paid plans.
Still a fit?
If none of these block you, try it on the official site.
