Undetectable AI technology in IA Checker
Undetectable AI is a humanization API that IA Checker includes in the suite on eligible plans. You use it from an IA Checker account, next to detection and the other writing tools on iachecker.com.
What Undetectable AI is
Undetectable AI rewrites AI-sounding drafts so they read more naturally. It is a third-party humanization technology. IA Checker is not Undetectable AI; we call its API from inside our product when your plan includes that option.
This page describes the technology in plain terms and where it sits in the suite. It does not claim that any rewrite beats every detector, and it does not sell Undetectable as a separate brand you manage outside IA Checker.
Plans that include it
- Max includes Undetectable AI on monthly and yearly billing.
- Plus and Pro include Undetectable AI on yearly billing.
- Starter does not include Undetectable AI. Confirm on the live pricing page before you subscribe.
What the technology does
The Undetectable AI API takes source text and returns a rewritten version aimed at sounding less mechanical. In practice that means changing rhythm, wording and structure while trying to keep meaning intact.
Inside IA Checker that call is one humanizer path among others. You stay in the same account that already runs detection, paraphrasing and related tools.
If you only need a free detection check, open the AI Detector. If you want this humanizer option in the suite, create an account and choose a plan that lists it.
Humanization is not a guarantee
No humanizer can honestly promise that rewritten text will pass every checker forever. Models change, detectors change, and short or heavily edited samples behave differently.
IA Checker treats detection scores as indicators. The same caution applies after a rewrite: read the result, keep the facts, and do not treat a lower score as proof of authorship.
Use the Undetectable AI option when you want that rewrite path inside the suite. Use judgment when the writing has to stand on its own.
How to use it on iachecker.com
Create an account, open pricing, and choose a plan that includes Undetectable AI for the billing period you want.
From there, the humanizer surfaces in the toolkit expose the option when your entitlements allow it.
