Can you include an AI unit/lesson plan generator? You could market it as another level of common curriculum. I just sat through part of a webinar for connected PE and it's $99 per year. I didn't purchase it because I need more than just PE lessons, but you should consider adding one. I'd pay extra to have the features your planbook currently has and the ability to get it all generated by writing a prompt. Also, new teachers on alternatie paths can benefit from this service. It might just be the incentive districts like mine to purchase your program for its entire staff..
