This service likely violates rules against the unauthorized practice of law in many (most?) jurisdictions in the United States.
It uses the common for new and short-lived services (but, IIRC, not generally effective -- but don't trust me, see an actual lawyer) technique of using marketing language selling it in terms which describe legal advice, but then including a small print disclaimer at the bottom of the extremely long page saying that the analysis provided should not be treated as legal advice.
