The initial deal was based on several AI courses allowed for each tier, but later on, that was changed to a credit system, and I'm not sure how that translated into reality. Also, none of the tiers are mapped to their website pricing plans, so there's always uncertainty about which features will be available to Lifetime deal users. For example, user access was not included in the last deal, and now my Tier 2 deal has no access to it because they started it with Tier 3 plans. So, I'm forced to upgrade to Tier 3 (even though I don't need the extra credits) or subscribe to their regular plans. The tool has potential, which is why I bought the deal in the first place, even though it wasn't intuitive or usable. Now, I don't use it at all. Additionally, in the AI-generated quizzes, most of the time there are no images present, or wrong images are being inserted in the questions. It's not convenient to put images one by one in each question after the questions are generated, and this is just from a small test I ran.
