Midjourney is a powerful text-to-image software. Everything you can imagine, you can create in seconds, just by describing what the image should look like.

Midjourney runs through Discord and therefore you need a discord account to use Midjourney.

The Midjourney team describes their service this way:
Midjourney is an independent research lab exploring new mediums of thought and expanding the imaginative powers of the human species.
We are a small self-funded team focused on design, human infrastructure, and AI. We have 11 full-time staff and an incredible set of advisors.
