Generative AI supports issue coding and document insights, including descriptions, summaries, rationales, and supporting excerpts. Using purpose fit AI workflows for different tasks gives legal teams and Lighthouse experts greater control over process and validation and improves accuracy and outcomes.
IQ Review uses an LLM-powered, exemplar-based workflow to predict whether documents are responsive. Subject matter experts train the model using matter-specific responsiveness criteria, review validation samples, and determine the appropriate cutoff. Lighthouse experts support model configuration, monitoring, validation, and reporting. This structured process helps legal teams reduce the number of documents requiring manual review while preserving counsel’s control over responsiveness decisions.
IQ Review uses generative AI to apply issue codes to responsive documents based on counsel’s matter-specific issue framework. It can also generate document descriptions, fact-based summaries, rationales explaining why particular issue codes apply, and excerpts grounding the analysis in the document. Counsel validates sample outputs before applying the workflow broadly. The resulting fields help teams organize responsive documents, accelerate quality control, and explore important issues during case preparation.
