Pricing FAQs
Everything you need to know before you choose a plan.
Is there a free plan?
Yes. The Free plan includes 5,000 words per month, basic humanization and AI detection, with no credit card required. Document upload and formatting preservation start on Lite at $6 a month.
What happens if I hit my monthly word limit?
Humanization pauses for the rest of the billing cycle once you reach your plan’s word budget. You can upgrade at any time to instantly unlock a higher limit, and your allowance resets at the start of each billing period.
Will UnMarkedAI help my text get past AI detectors like Turnitin and GPTZero?
UnMarkedAI restructures sentences and varies rhythm to reduce the patterns detectors flag, and shows you exactly which sentences look AI-generated so you can refine them. No tool can guarantee a result on every detector, so we give you a built-in detection view to verify before you submit.
Can I switch plans or cancel anytime?
Yes. You can upgrade, downgrade, or cancel from your billing portal at any time. There are no long-term contracts and no hidden fees — changes take effect from your next billing cycle.
What is the difference between monthly and annual billing?
Annual billing gives you two months free — you pay for ten months and get twelve. The plan limits are identical; annual simply lowers your effective monthly cost.
Is a higher plan actually better value, or just a bigger allowance?
Both, depending on the step. Lite to Pro lowers your cost per word — Pro stretches roughly twice as far per unit of spend as Lite — while Business is priced for what it unlocks: API access, a team workspace and usage analytics, alongside a much larger allowance. Every card shows its exact words-per-unit rate, so you can compare before you upgrade.
Do you offer plans for teams or high volume?
Yes. The Business plan is built for agencies, institutions and high-volume users — it adds API access, a team workspace and usage analytics on top of everything in Pro. If you need more than Business covers, contact us for a tailored quote.
