I know I called myself lazy but there is a lot of people who are lazy or just not paying attention in this thread. The number of people who go and use the wrong bot for the wrong thing and then blame the bot is exasperating. From basic research I've determined:
Dall-E is for generally anything but is extremely limited access and highly censored.
Midjourney is for fantasy, horror, and psychedelic things, mostly in traditional and digital painting style. It is also limited access.
Craiyon is Dall-E but worse in everything but cartoons and vidya, where it strangely excels but has an absolute inability to draw faces. It is less censored than Dall-E and free.
Stable Diffusion is for photorealism and paintings and it is very bad at drawn mediums like anime unless you put in specific modifiers like artist names and styles. It is currently uncensored and free.
Novelai is for weebs and was built off of Danbooru, so functions off of their tags with a specific skew toward being women-focused, but is worse at mimicking copyrighted works than the others. It seems to also be uncensored, but is not free unless you get the leak and run it on your own hardware.
Perhaps with this guide people will start using the correct bot for the right thing and not fighting over 'it's only good for animu' 'oh yeah but its bad at animu'. Also: it doesn't hurt to go take some time to read up on tutorials and figure out the bot's language before you judge the quality of the bot. It's not the bot's fault if you can't speak its language and it gives you an image of gibberish because you spoke gibberish to it.
