DupDub price and terms

Terms

Free to start
PartlyPartly
The terms in full

A 3-day free trial, not a standing free plan: the Free card reads "3-day free trial" with "No credit card required" and "Personal use only", so the audio may not be used commercially. The page disagrees with itself on the size of the grant: with the Monthly tab selected the card reads "3-day free trial of 10 credits", with the Annually tab selected it reads "3-day free trial of 5 credits", and the FAQ "Is it possible to try DupDub for free?" says "a complimentary 3-day free trial with 5 gifted credits". The comparison table's Credits row gives the Free column as "5 credits/3-day free trial".

Promotion and regular price

yearly shown monthly. The pricing page opens with the "Annually 25% OFF" tab already active, so the first figure a visitor sees for the entry plan is $11 a month, which is the annual rate quoted per month alongside "$132 billed annually". Clicking the adjacent Monthly tab shows the regular month-to-month price of $15 a month, and the same switch moves Professional from $30 to $40, Ultimate from $110 to $150 and Scale from $250 to $300. The 25 percent is the vendor's own printed figure, not a calculated one; no limited-time new-customer promotion is advertised on the page, and the discount FAQ points only to occasional Discord promo codes.

Past your allowance

Extra credits are sold outright on the page's third billing tab, Pay as you go, as lifetime credit packs: 500 credits for $68, 1,000 for $128 and 6,000 for $698, each carrying the same unlimited commercial license and API access as a subscription. The page states no automatic per-credit overage rate and does not say what happens the moment a month's allowance is exhausted; unused credits are not lost, since the FAQ says they roll over to the next subscription month.

Commercial use

Publishing rights begin on the cheapest paid plan: Personal, Professional, Ultimate and Scale each carry an "Unlimited commercial license" line, and the pay-as-you-go credit packs do as well. The Free option is excluded, since its card is marked "Personal use only" and the pricing FAQ confines commercial use to a paid subscription, so nothing you make during the 3-day trial may be published commercially.

API

Every paid creator plan card lists API access as an included feature, starting with Personal at $15 a month, and the three pay-as-you-go credit packs list it too; the Free trial card does not. The same page contradicts this in its comparison table, where the APIs section's only row, "All AI tools", carries a grey cross rather than a green check in all six columns including Business, so the plan cards and the table disagree about whether any tier gets it.
