Spent hefty on the highest tier hoping I could start becoming productive with my knowledge base. But it turns out hardly making something useful. Sometimes the search doesn't return anything, and other times it fetches irrelevant data. And even if it does find something, the answer is incorrect. For example, asking for the latest updates of a specific project name on JIRA returns JIRA product updates from Gmail. It's supposed to save me time, and not taking my time to guess or experiment. So I stopped there to avoid wasting more time after 30 min getting nothing. Tried again weeks later, and no difference. Now with the last try a few days before my refund is due, I have no choice but to return it.

Note that my results are not related to the outage happened on 8/21.
