Unlike knowledge hubs, which primarily store entire documents, clause banks allow for the storage, organization, curation and management of clauses or provisions. This is particularly helpful for specialist practices, such as tax and employment, which work by reviewing existing documents and inserting relevant clauses. In a clause bank, these practices create libraries of clauses with folder structures and taxonomy tags that enable lawyers to rapidly identify the right content to add to a document. Some clause banks, such as Litera Content Companion, provide capabilities such as auto-redaction and the ability to automatically break down a document into its composite clauses. It is also common for sophisticated clause banks, including Content Companion and Syntheia, to offer contemporaneous clause recommendations during drafting. A recent competitor is Lexis Create, though this is currently a UK-focused product.
