How is WeSearch different?

Traditional tools, whether in e-discovery, file management, or case management, all leave you at the mercy of keyword search. Unless you can remember the exact wording in a document, it is difficult to find what you need quickly. With WeSearch, you can finally escape the prison of the keyword. By leveraging a breakthrough in artificial intelligence called a transformer-based neural net, WeSearch matches your queries by concept rather than by literal keyword.
