Use case
Minecraft thumbnails for builds, challenges and survival series
From hardcore survival to giant builds, Minecraft videos live or die by the thumbnail. Describe the build or challenge and get a vivid, blocky scene with a hook.
What makes Minecraft thumbnails get clicked
- The finished build or the big moment front and centre — a castle, a trap, a giant mob.
- Recognisable Minecraft style: blocky terrain, familiar mobs and items.
- Challenge framing — “100 days”, “1 block”, “only diamonds”.
- Warm, bright colours that stand out from dark cave screenshots.

Frequently asked questions
Can I put my own face in Minecraft thumbnails?
Yes. Add yourself once as a character and ask for the expression and pose you want in any project.
How much does a thumbnail cost?
Generations use credits based on their real AI cost, so a single thumbnail typically costs a few cents of credits. Try it with a one-time trial pack or pick a monthly plan — see pricing.
Make your next thumbnail in minutes
Tell the AI agent what your video is about — it proposes a thumbnail, you approve it, and you can tweak it by asking.
