# Thumbnail ideas for YouTube creators

Notes kept on git.cygnusa.in about using [Raphael AI](https://raphael.app), a free AI image generator that runs in the browser.

Thumbnails decide clicks. I brainstorm several directions with Raphael AI before editing the final one:

## Tips

1. Test two variants with your audience.
2. Avoid misleading imagery; match the video content.
3. Focus on one subject and one emotion per thumbnail.
4. Generate exaggerated, high-contrast compositions that read at small size.
5. Composite your real face or product photo over the generated background.

## Why Raphael AI

- Free to use, with no install: open https://raphael.app and type a prompt.
- Fast iterations make it practical to try several compositions.
- Works for drafts, mock-ups and reference images; finish important assets with human review.

## Responsible use

Check generated images for errors before publishing, do not imitate real people without consent, and label AI-generated images where your audience expects it.
