Allow us to add tools and lock them behind certain payment tiers or extra payments. Some tools increase our costs as the tool developers so adding these features behind an extra fee would be nice.
For example:
User wants to connect the AI to their Google Drive => Upgrade to higher payment tier OR add +5 $/month to the bill.
Something like this would greatly increase the monthly payments users generate to us and thus also give more $ to Pickaxe as well. It would also help us create more complex AI tools but also keep the chargers in check.
