Are the cases ChatGPT gave you fake or not? Check whether the cases cited are real or not with a direct link to the case opinion. This tool is useful when getting information from ChatGPT or other AI tools used for legal research that can make up cases out of whole cloth. Enter the block of text that contains the cases, e.g. table of authorities. The case names do not need to be formatted in any particular way and can be mixed with other text. There is a limit of 64,000 characters per request. Thanks to our friends at the Free Law Project for this functionality.
