Your tool looks like a lifesaver at first. I don't use Notion, but I'm in the market to replace my blog provider and I'm somewhat enamored with these tools that use trusted and common services as a backend.

But why only 100 posts? I see this isn't an artificial limitation just for AppSumo as your starter tier has the same limitation. This seems amazingly restrictive. I'm not asking you to change this, but I wouldn't feel comfortable buying unless I know the business logic behind this restrictively low number. That's less than one year of blogging if you post twice per week!
