About Undetectable AI
Undetectable AI is an online AI text detector and humanizer that rewrites text to read as human, with an image detector, Chrome extension, API and other writing tools on the same account.
The rule that matters most for price: plans are sold by words per month, and switching to yearly billing is shown as 50% off.
Christian Perry, the CEO and co-founder, created Undetectable AI, and chief communications officer Devan Leos is the other co-founder. The company says the idea came in January 2023, when Perry concluded that most AI-generated writing sounded robotic and was easy to flag; before that he founded Chatterquant, which was later acquired. Undetectable Inc. is based in Sheridan, Wyoming.
Beyond detection and humanizing, the toolset covers a paraphrasing tool, an essay writer, a plagiarism checker, an AI job applier and detectors for voice, video, deepfakes, fake PDFs, receipts and IDs. Users must be 18 or older, and businesses can arrange custom plans with white labeling.
When shoppers look for Undetectable AI coupons
Undetectable AI coupon searches peak in September, about 1.5× a typical month, and dip lowest in July.
Undetectable AI shipping, returns and perks
- Plans
- Yearly billing runs $60 a year for 10K words a month, $114 for 20K and $189 for 35K, with a 50K tier above.
- Yearly discount
- The plan toggle labels yearly billing as 50% off, while the menu marks pricing as a sale, so it may not be permanent.
- Free trial
- A 250-word free trial lets a short document run through the humanizer before any plan is bought.
- Guarantee
- When humanized text is flagged by an AI detector, sending the document and the flagging tool to support refunds that generation's cost.
- Business use
- Custom business plans carry non-expiring credits and white labeling, and bulk team or API pricing is arranged through sales.
- Eligibility
- Accounts are for users aged 18 or older; the operator is Undetectable Inc. of Sheridan, Wyoming.

How to use a Undetectable AI promo code
- Undetectable AI sells subscriptions rather than products, so any promo code belongs to the plan purchase, not a shopping cart; where the code field sits was not confirmed from the pages read.
- Pick monthly or yearly billing first, because the yearly toggle already shows 50% off and no published rule says whether a code stacks on top of it.
- Running a draft through the 250-word free trial before paying costs nothing and shows whether the humanizer suits the writing.
- Teams that need bulk words or API access get pricing from the sales team instead of through a public code.
More ways to save at Undetectable AI
- The one discount shown on the pricing page is yearly billing, labelled 50% off, which brings the 10K-word plan to $60 a year.
- Choosing the smallest word tier that covers real use matters more than any code, since the 20K and 35K plans run $114 and $189 a year.
- Heavy users and agencies can ask sales about custom business plans, whose credits never expire, and about bulk team or API pricing.
- The money-back guarantee also limits the cost of a generation that still gets flagged.
