Goodlookup is a smart function for spreadsheet users that utilizes a pre-trained model, Intuit GPT-3, to provide better text-to-text record linking. It helps solve problems related to data scattered across multiple places with no uniform name convention. Goodlookup matches similar text in a way that's similar to how humans would, taking into account semantic relationships, synonyms, and cultural similarities between text strings. It can replace traditional fuzzy matching and score matches based on the intensity of neighbor word vectors in the longer string.
