Generating images

Image generation has been around for a while with OpenAI's Dall-E being the first really hyped AI application. Google recently added image creation to Bard in collaboration with Adobe.

DALL-E

Solidify's OpenAI instance has a DALL-E playground for experimenting with image generation using prompts.

Microsoft Designer

Microsoft Designer has prompt based image generation as part of its design a marketing campaign portfolio. It allows you to import your own picture and use that in the campaign designs instead.

Chat-GPT

Chat-gpt doesn't generate pure images directly, but can generate mermaid code to represent flow diagrams and such. A slightly limited range of mermaid code can be inserted directly into markdown files; it may need some tweaking. You can also put the mermaid code in mermaid live and then screen shot the preview for other use cases.
