I purchased Tier 4. I have been testing a number of AI visibility tools, and so far I have found this one the easiest to use. At first I thought that the article generations were per month, but they are lifetime...but no big whoop...they have a BYOK! I wanted to share the results with a client...so I got on chat and asked how I could add a user to a workspace, and you can't, but you can create a custom report link (white-labeled, by the way) so bingo! The insight into chats is amazing...the best I have seen. Everything I find just keeps making it better and better. I will be setting up an onboarding call (after playing with it for a few weeks) to get a deeper dive. I also think I may upgrade to tier 5.
