How does CoCounsel address hallucinations?

Through retrieval augmented generation (RAG), CoCounsel bases its answers on legal authorities, documents, and other verified datasets to minimise ‘hallucinations’ and similar errors. CoCounsel is intended to assist legal professionals, but it should not replace human expertise or due diligence in legal decision-making. Users are encouraged to verify any critical information and exercise professional judgement when utilising outputs.
