CoCounsel leverages the latest breakthroughs in A.I. technology to perform a wide range of sophisticated legal tasks. CoCounsel runs on a large language model, but it differs in a number of critical ways from ChatGPT and similar “chatbots” that use publicly-available large language models. These differences, summarized below, make CoCounsel a secure platform that attorneys can trust for accurate, reliable information.

  • Specific legal applications: CoCounsel offers a suite of applications that have been specifically developed for litigators and transactional attorneys. These applications have been trained on the primary law and other legal documents to serve the particular needs of litigators and transactional attorneys. By contrast, ChatGPT and similar chatbots that run on public large language models were not developed for attorneys and are not intended to be used in the practice of law.

  • Extensive testing: CoCounsel has been rigorously tested by Casetext’s internal team of litigators and transactional attorneys, who work closely with Casetext’s AI engineers to ensure that CoCounsel’s answers are accurate and can be used by attorneys in their daily practices. All of CoCounsel’s applications have been subjected to thousands of internal tests. After clearing the internal testing phase, CoCounsel’s applications are then released to our beta testing group, which is composed of hundreds of attorneys from elite boutique and large law firms, for additional testing before finally being released to the public.

  • Guardrails against “hallucinated” authorities: CoCounsel’s legal research application retrieves information from the primary law only. By contrast, ChatGPT and other public AI models do not have these guardrails in place and can therefore make up or “hallucinate” legal authorities that do not actually exist.

  • Daily updates: CoCounsel’s legal research application pulls from Casetext’s database of primary law, which is updated daily. No such regular updates exist for ChatGPT or other public large language models, which can generate language based on information that is more than a year old.

  • Know whether you are citing good law: All cases cited by CoCounsel are checked by Casetext’s “SmartCite” citator to determine whether those authorities are still good law. No such protections exist with ChatGPT or similar public AI models.

  • Robust security protocols: Casetext is deeply committed to security and privacy and has implemented rigorous security protocols to maintain the confidentiality of your data. All data you provide to Casetext when you use CoCounsel, including any and all information and documents you choose to upload to CoCounsel, are encrypted and protected in accordance with Casetext’s comprehensive security program. None of your information or documents are shared or used to train the CoCounsel platform or the underlying large language model. These security measures do not exist with chatGPT or other public large language models, where your data can be accessed and used by others.
