This looks a lot like ChartDB[0]. Is that correct? If so, how would you compare the two tools, or better yet, distinguish yours from theirs?
It seems like your project is more grassroots than theirs, so hopefully you can use it to make some money... Not sure how your platform works, but do you provide (paid) storage, syncing, multi-user collaboration, etc.? That seems like the predictable monetization strategy.
