It is an AI, not a person: nobody looks at your individual case, and we do not know who signs up or for what reason. That is why we give pointers, but no legal advice on the individual case. Guidelines and playbooks in the platform are only guardrails: the AI relies on the available sources and your information. AI can make mistakes — check important results, and if in doubt, ask a lawyer.
