How Thumby credits work

Thumby uses a pay-as-you-go credit system. You buy credits once and use them whenever you need to generate thumbnails — credits never expire. There are no monthly subscriptions, no recurring charges, no cancellation hassle.

Each thumbnail generation uses one credit. A credit gets you three to five thumbnail variations from one video idea — pick the best, or A/B test multiple. Style cloning, 4K output, and Shorts format are all included at no extra credit cost.

This pay-as-you-go model is rare in the AI thumbnail generator category. Most competitors lock you into monthly subscriptions with usage limits that reset every 30 days regardless of whether you used them. With Thumby, the credits you buy stay yours.
