Person Best Practices

Learn how to create the perfect person for AI thumbnail generation

A person is used inside your thumbnail to generate your face instead of a random one. Here are the best practices for creating effective persons.

Image Recommendations

Use Two Different Images

I recommend using exactly two images that look different:

  • One from the left side, one from the right side
  • Or one facing forward, one from above

The key is to implement different positioning so the AI can be more accurate with your face.

Capture Only Your Face

Make sure to capture only your face. Avoid having any outfit visible in the image.

Even just a visible outfit will make the AI always generate that same outfit by default (e.g., a black outfit if that's what you're wearing).

You must ensure that each image you use has no unnecessary details at all - only what you want to appear.

If you want a specific element like a cape or gold chain, keep those - but be intentional about what you include.

Setting Up Person Details

The Name Field

The name you give is not sent to the AI, so it's just for your organization.

The Description Field (Critical)

This is really important. You should include:

  • Your age and physical characteristics
  • Details about your face (beard, glasses, etc.)
  • What you don't want (e.g., "no beard" if you don't have one)

This will help the AI place you correctly in the thumbnail.

Example description:

30-year-old male, brown hair, no beard, wearing glasses

What to Avoid

Hands in Images

This is a really bad practice. If your reference image includes hands, you'll get many thumbnails generated with hands appearing incorrectly.

Hands are difficult for AI to generate correctly, and including them in reference photos often results in errors.

Inconsistent Styles

If your images have inconsistent styles (e.g., one cropped differently than another, different lighting, different backgrounds), you'll get the worst results.

It's really important to maintain consistency across your reference images.

Backgrounds and Extra Elements

Avoid images where there's a visible background, chair, earbuds, or other accessories.

Try to remove:

  • Backgrounds
  • Furniture
  • Accessories (earbuds, headphones, etc.)
  • Props

All of these will confuse the AI and potentially generate fewer good images.

Summary

  1. Use 2 images with different angles
  2. Capture only your face, no outfits
  3. Fill in detailed descriptions
  4. Specify what you don't want
  5. Avoid hands in images
  6. Keep styles consistent
  7. Remove backgrounds and accessories
