Thumbnail ideas for YouTube creators
Notes kept on git.cygnusa.in about using Raphael AI, 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
- Test two variants with your audience.
- Avoid misleading imagery; match the video content.
- Focus on one subject and one emotion per thumbnail.
- Generate exaggerated, high-contrast compositions that read at small size.
- 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.
