Oh, and, wow. Underwhelming options. Our code is open source, free to use, no login, host on your own box & more.
Also, I fail to see a Terms of Service, only Privacy Policy, on your site. Odd. Makes me uncomfortable, honestly.
It's always a mystery to me how some stuff gets attention (like this) and other things get ignored; maybe because this, "Innovation," seems 100% aimed at making Twitter less accessible to visually impaired?
PS: we store the images we build as layers, so, we keep the text and can include it for later analysis, along with the background color used, font & more. In addition to tracking stats for you on the content you make, to see how well it performs on Facebook.
Sigh; would be cool if you'd add that to your roadmap. Or perhaps just relaunch with our code?
