    If you text 8145594701, it will send back an image with the prompt you specified. Currently only US numbers can send/receive texts because Twilio. Sorry to the rest of the planet! I think this will likely fall over but I figured this would be a cool little thing to demo. I removed the NSFW filter so be mindful of your prompts! I don't persist numbers and there is no linkages being saved between the original text message and the generated images.
