How can this be true:

"The #1 tool to automatically generate..."

You are in early access.

I suggest you review your copy. There is a way to communicate a similar message without outright exgerating. In fact, you already have such copy:

"Instant cover photos for every. social. media.

Do not repeat yourself. Voice your brand consistently across all social media."

"Your #1 tool..."?

I think that might have the same connotation the dev wants people to feel about their product without being a full-on lie. I've never been in a position to push back against blatantly false copy from a marketing position, but I have too many times rolled my eyes at what was being pushed. This one just happens to be a single word change to make it much less egregious.

while the concept looks simple enough, i think it would covey the idea better to have actual screenshots from the various platforms.

also, if you want to get more people using i would suggest creating a wordpress plugin since that is the platform that most digital agencies (your target market) use for SEO.

No pricing, but I think it is like a $1.25 / mo, based on their 'cost savings' slide.

Also, so nifty templates for doing the work yourself for free.

Test the site a bit more. On the iPhone scrolling keeps jumping down as if images are loaded offscreen.
