Attorney, who began using Counsel Stack at his practice, said the platform became “an invaluable tool” for research.
All of the AI products outperformed the Lawyer Baseline across the three scoring criteria. Counsel Stack received the highest score across all criteria.
If a legally trained mind diligently develops their backend algorithm and works on properly encoding the “method” behind the madness, then there exists a serious potential to unlock or build an AI that is entirely competent and capable of not only pulling relevant citations from relevant case law on point to the issue at hand, but also capable of verifying the authenticity of those citations that are sourced using the LLM‘s brain.
It’s no longer a “ok, sure, it could be built” scenario. It’s here. Counsel Stack is incredibly easy to use and affordably available today.
