Billing questions
What counts as a word?+
Words in the text you paste. A 400-word essay uses 400 words, whichever engine you choose. A rewrite that fails is not counted.
Can I cancel anytime?+
Yes. Cancel from Billing in your account. You keep your plan and words until the end of the period you paid for.
Do you offer refunds?+
Yes, within 7 days of your first payment if you have used 5,000 words or fewer. Write to support@ai-humanizer.dev from the email on your account.
Do unused words roll over?+
Monthly words last until your next renewal. Yearly plans give you the full year of words at once, valid until the end of the year you paid for.
How do I pay?+
By card through Stripe (Apple Pay and Google Pay work too). We never see or store your card number.
