Use case
Podcast thumbnails that make people press play on a long episode
A two-hour episode is a big ask. The thumbnail has to promise one irresistible idea from the conversation — and show who is in it.
What makes podcast thumbnails get clicked
- Recognisable faces of the host and guest.
- One bold idea from the episode, not the episode title.
- A consistent show frame — colours, layout and logo in the same place.
- Emotion: laughter, disagreement, surprise.

The quote
A short, provocative line from the guest, very large.

Frequently asked questions
Can I put my own face in podcast 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
