UberCreate alternatives

As a global digital marketer at work and also a VPPR at a Toastmasters club, I always need to prepare for online/offline activity promoting materials like posters. It's time-consuming to design or choose the most suitable background images from a large pile of pictures every single time, also, although I can see a variety of images online, I want something unique that totally belongs to me and nobody else has used before. Accidentally, I found this app called PicSo, which was recommended by my friend who is a game illustrator. She was invited to use PicSo about 2 weeks ago. I just got so astonished that I can generate my own exquisite image through inputting texts! According to my friend's feedback, I also got to know that there are other similar products like Midjourney. But as you all know, Midjourney relies entirely on Discord's bot server, which can limit people's creativity a lot. Both my friend and I desperately needed a mobile app that would solve our problems. When I learned that PicSo is a mobile app and did not rely on SD's open-source code, but was developed entirely by the team behind the product, I was very interested in it. I started getting involved with the enthusiastic user community and giving some suggestions. Fortunately, the team took some of my advice. I have seen the technical pursuits and efforts of this team, and I have also witnessed how they overthrow themselves and strive to establish their own influence in this field. I appreciate such professionalism. Currently, I've started using PicSo for my poster creating, and my friend has also started using the app for her illustration manuscripts. I can really see how the team stands out in some aspects. I hope they can maintain this enthusiasm for research and development so that the entire industry will have more excellent products for users to select.
