I haven't yet exhausted my monthly AI credits in Logos Max yet in any month.
However, with AI features becoming more mainstream in Logos, I could see where users could exhaust their monthly credits.
A nice workaround would be a way to purchase bundles of AI credits in the event a user continually exhausts their AI credits.
Once purchased, the unused credits would stay "banked" off to the side, then be used during months a user exhausts their monthly credits.
Almost like "overdraft protection" where a "savings account" kicks in and covers the balance for an overdraft checking account.
That would allow AI heavy users to continue using AI on those months while still providing a revenue source to cover the AI use.
