Describe your images#
Under each image there is a box for a description (alt text). It is read out to people who use screen readers. Social9 reminds you when an image has none.
Create an image with AI#
- Press Create image with AI.
- Describe what to show under What should the image show? For example: "A warm loaf of sourdough on a wooden counter, morning light".
- Pick a Shape: Square 1:1, Portrait 4:5, Story 9:16 or Wide 16:9. Social9 picks a sensible one for your networks.
- Pick a Style: Photo, Lifestyle, Flat lay, Illustration, Minimal or Bold colours.
- Choose 1 option or 2 options.
- Press Create image (or Create 2 images). It takes up to a minute.
- Press Use this image, or Edit this image and say what should change, for example "Make the background white".
The AI does not add text, prices or logos unless you ask for exact words.
| Image | Credits each |
|---|---|
| Standard | 10 |
| Sharper switch on | 20 |
If it takes too long and stops, you are not charged for unfinished images.
