常见问题
What does this tool create?
It generates social media images from a text prompt, automatically sized for the platform you choose so they display correctly in-feed or as a thumbnail.
Do I upload an image or describe one?
You write a prompt describing the visual you want. The tool generates a new image rather than editing an uploaded file.
Which platforms and sizes are supported?
It supports common formats for Instagram, Facebook, X (Twitter), LinkedIn, and YouTube, including square, portrait, and landscape ratios optimized per platform.
Can I add text or captions to the image?
AI-rendered text can be unreliable, so keep on-image words short or add captions yourself afterward. The tool focuses on the visual itself.
Can I use the images commercially?
Yes, generated images can be used for business social accounts, ads, and promotions.
How do I get the best fit for a feed?
Choose the target platform before generating so the aspect ratio matches, then preview how it looks at thumbnail size.
Are my prompts stored?
Prompts are processed only to generate the image and are not published. Download what you want to keep.
What does it cost?
Free gives 5 generations per day with no signup. Pro is $19/month.
