"The first 10 cards will be generated. Upgrade to Pro for up to 30 cards".

I'm a BRAND NEW USER making a first impression. This is the primary use case for your product: I imported a 60 minute presentation that I intend to edit and improve for re-delivery in a few weeks in order to try out your product and see if it adds value.

I want to try out your product, but this line appears at the bottom of the first screen I encounter after I upload. I've not yet received any value from your product, and it appears that I have to pay you to learn whether there is any.

I do not yet know what a card is; my context is 'slide'... as is all the other BRAND NEW USER traffic. I assume you want me to buy a subscription to produce anything greater than 10 slides.

I strongly recommend that you change both the business policy and the words you are expressing it with. The whole point of freemium is to allow a user to experience value and convert to a paying model based on a threshold of use above basic. This threshold of use is poorly explained, and appears to be far below basic.
