Is Fluent Forever free?

Could you please clarify for me, is the resource "Fluent Forever" available without any cost? I'm interested in exploring its content but I'm also mindful of budget constraints. Is there a free version of Fluent Forever that I can access, or do I need to purchase it to enjoy its full benefits? I'd appreciate it if you could provide me with more information about this matter. Thank you for your assistance in this regard.
