A thumbnail needs one idea, a face and three to five words you can read on a phone. Nano Banana Pro is the default because it renders text cleanly. Add your photo and it becomes the face of the thumbnail.
How it works
- Enter the title and the words to show
- Describe the scene and add your photo
- Generate a few options and A/B test them
Tips for better results
- Keep the text short. Five words is a lot at mobile size.
- Big faces with clear emotion beat busy scenes.
- Make two or three versions to use YouTube's thumbnail test.
What people make with it
- YouTube videos and shorts covers
- Podcast episode art
- Course and webinar covers
