Questions

Is our legal research tool high-risk?

Not for a law firm or an in-house team. Point 8(a) of Annex III turns on who uses it and how: by or on behalf of a judicial authority, to assist in researching and interpreting facts and the law and applying it to a concrete set of facts, or in a similar way in alternative dispute resolution.

Does professional secrecy change the AI Act duties?

Not the duties themselves: the AI Act classifies by intended purpose, not by profession. Confidentiality and data protection rules apply alongside it, and Article 4 still has the firm take measures to support the development of AI literacy of the people using the tools.
