Subscription website with access control?

I made a generator tool for students and teachers and I want to sell it for a monthly fee.

I plan to have a:

• Free model (let's say 3x access per month)
• Limited model (10x access per month)
• Unlimited model

I created a WordPress website for it and tried different plugins like Memberpress and Paid Memberships Pro.

They can all "restrict" the page where the generator tool is found. But I can't find any option to control the access/month.

Is there a way to do it?

Note: I'm not a developer, though I can code a little, but not too much.
