* The demo is too slow. Add a simpler version with images so I can see at a glance what it does. I'm not interested in how many buttons I must press. (Don't delete the video. If I decide to use the product, it may be helpful.)
Do you have an option for fancy colors and backgrounds of the slides? People really like colorful presentations. (Not me, but most people like colors and sparking transitions.) Can I add the logo of the business/conference/whatever automatically?
The blog is empty! It is easier to get traction here if you identify an interesting problem that you have to solve in this project and write a nice interesting blog post about this. Just imagine that an old friend visit you after a few years and you want to tell an interesting/funny story about the project. Which one would you choose?
(Do you handle other languages? What about different spellings of English? Do you detect list in Word/Pdf when they have the official format or also markdown-like list? If a list is too long, do you split it? Do you copy images from the doc/pdf to the slides?)
