Questions
AI detector FAQ
Which languages does the AI detector support?
The AI detector supports 24 languages: Arabic, Chinese (Mandarin), Czech, Dutch, English, French, German, Greek, Hindi, Hungarian, Italian, Japanese, Korean, Persian, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Turkish, Ukrainian, Urdu, Vietnamese.
Is the AI detector really free?
Yes. Guests can run 20 checks a day without creating an account. A free account raises that to 50 checks a day once you verify your email. Unverified accounts share the guest allowance for their IP address.
How many checks do I get each day?
Guests get 20, the Free plan gets 50, Basic gets 100, Standard gets 500, and Premium is unlimited. Paid plan limits apply while the subscription is active.
When do my checks reset?
Daily allowances reset at midnight UTC. Your remaining count is always visible above the text box.
Is there a word limit?
Yes. Each check accepts 61–1,990 words. Text shorter than that does not give the detector enough signal, and longer passages should be split into separate checks.
Do I need to install anything?
No. The detector runs in your browser on this page. You can also use the DecEptioner Chrome extension for rewriting and humanizing while you browse.
Is my text stored?
Your text is used to run the check and is not saved as detector history. Usage counters only record how many checks were made.
What if I hit my limit?
Guests can create a free account and verify their email to get 50 checks a day. Free and paid users can move to a higher plan from the pricing page at any time.
