"Unfortunately, we cannot provide a description for this tool as it promotes the use of dark magic and the involvement of spirits, which is not a legitimate or safe practice." ..but those other AIs generating anorexically thin women with huge bazongaloos is totally fine. Especially when it involves NSFW stories about your adopted goth sister, your daughter's hot best friend, or even the hot slave you just bought. Totes safe practice. Cmon guys.

It solved a tricky question at the first instance. Although, when I asked this question again, it missed it just by an inch. 4/5, highly recommended.
