I want to make sure I’m understanding the Gumlet tier structure correctly. The two main features that attract me—multilayered DRM video protection and the AI-generated chapters/review tools—are highlighted as the top benefits in the TLDR. But when I look at the tier breakdown, it seems that DRM only becomes available from Tier 5, and the full DRM + AI engagement tools are restricted to Tier 6. Since these are positioned as the strongest points of the offering, I just want to confirm whether they are truly limited to only those top tiers. I also need clarity on the monthly streaming bandwidth: how is it calculated, how many terabytes are included per month, and what counts toward the usage? I need to understand these limits clearly before making a decision.
