Frequently Asked Questions
Are the tools really free?
The AI Detector is free with no daily limit and no signup. The AI Humanizer, AI Rewriter and Grammar Checker each give you 3 free runs a day before you need a plan. Nothing is watermarked, and nothing asks for a card to start.
How does the free tier work?
There is no trial to start or expire: the Humanizer, Rewriter and Grammar Checker give you 3 uses a day, every day, and the counter resets at midnight UTC. If you need more, paid plans start at $9.99/month. The AI Detector is not metered at all.
How do I cancel or change my subscription?
You can manage your subscription anytime from your Dashboard. Changes take effect at the end of your current billing cycle. You can also contact us and we'll handle it for you.
What is your refund policy?
We offer a full refund within 7 days of purchase if you have used less than 20% of that month's word allowance, and it has to be your first refund. Past 20% we refund the unused share instead. We will not argue you out of it, but those are the conditions — see the refund policy, or email us at miles@codaone.ai.
