DETAILED REVIEW:
I purchased the License Tier 2 plan (12,000 credits/month) in November 2024. The tool itself is quite powerful and offers great features for content creation and research. The ability to access multiple AI models from one interface is a genuine time-saver.
However, I've encountered a significant issue: the monthly credit renewal system isn't working as advertised. Since my initial purchase, the credits haven't reset monthly as promised. The renewal date keeps shifting without explanation (recently moved from January 23 to February 23), effectively leaving me with just the initial 12,000 credits for an extended period.
