Counsel Stack earned 77% on authoritativeness compared to 68% for attorneys and 70% for OpenAI.

This gap represents real professional liability protection. Every Counsel Stack response includes exportable citation verification logs. You can prove your team did their due diligence.

Counsel Stack is not a law firm or your lawyer. Our software is designed for attorneys and legal professionals. Nothing on this site constitutes legal advice. Nothing can substitute a real attorney when it comes to providing legitimate legal representation. If you need an attorney, find one, or email ai@counselstack.com, and we will connect you with our network of licensed attorneys in the relevant jurisdiction.

Similarly, Counsel Stack recommends that all attorneys using our platform follow the rules of professional conduct, standing orders, and other laws or regulations that govern the profession in their respective jurisdiction and practice area. Some jurisdictions require disclosure of AI use, others don’t. As a software company, we aren’t in a position to prescribe legal advice or a specific course of action.

Any actions taken by a nonlawyer user of Counsel Stack services must understand it is a software company, not a law firm, and therefore does not carry with it the protections normally afforded as part of the client-lawyer relationship. The recipient of any law-related services should not expect, for example, that the protection of client confidences, prohibitions against representation of persons with conflicting interests, and obligations of a lawyer to maintain professional independence apply to the provision of law-related services when that may not be the case.
