Banner-GPT alternatives

I have spent a ridiculous amount of time generating cards for pages and posts that I share on social media, so having a tool to speed that process up would be great! I've tried Canva but gave up because I couldn't find any templates that were aligned with my brand. They were all very designed out. I like that your tool keeps it simple so it's flexible. I really like the landing page. I found that the demo was a great way to understand the product. One bit of feedback: Maybe this is available in the Pro version, but I would love to be able to start with templates that are the right sizes for different platforms. Better yet, if you could somehow magically generate correctly-sized versions for each platform from just one main version that I edit, that would be amazing!
