The AI service is a scam as it is poor-generating AI. It hallucinates references; it doesn't generate the number of pages it promises to generate. It is limited to only 400 words, no matter what you select from the menu. It is such a scam and a hook to make students hire their fake specialists that pretend to help write your essay, while their AI service is a poor replica of GPT3.5. I demonstrated to them in chat that this is a fake AI essay writing tool, and they refused to refund the money I just paid on their fake website. I strongly recommend to AVOID their services!!!!
