Great idea and nice execution. The demo works great and there's definitely a wow-moment.
It's a bit unfortunate that uploading a keynote-presentation threw an error ( didn't say what the problem was, just that the presentation couldn't be converted ) and uploading a ppt messed up the charts. So, maybe it would be wiser to simply just accept pdf-documents and rely on users to do the conversion – it's a complicated task, versions change all the time and mastering pdf alone is maybe enough work for a mvp. just my two cents.
