Microsoft Designer is Microsoft’s AI-first design app, and it’s a fast way to get a first draft of a YouTube thumbnail. Instead of browsing templates, you describe your video — for example, “YouTube thumbnail for a beginner’s guide to sourdough bread” — and Designer generates several designs with images and bold text to choose from.
Key features include:
- Prompt-to-design generation for thumbnails and social graphics
- AI image generation from text descriptions
- A simple drag-and-drop editor for refining results
- Background removal and generative erase
- Resizing between thumbnail, banner and social formats
- Integration with Microsoft 365 apps and Copilot
It’s a handy option for creators who don’t want to design from scratch and just need a good-looking starting point quickly.
Microsoft Designer is free with a Microsoft account, including a monthly allowance of AI credits. Microsoft 365 Personal and Family subscribers, from about $9.99 per month in the U.S., get more AI credits shared across Microsoft apps.
Free credits are limited, template choice is smaller than Canva’s, and brand controls are basic. For quick, free AI thumbnail drafts, though, it’s a useful tool.
