Wordtune is an AI writing assistant by AI21 Labs that helps users rewrite sentences, adjust tone, and improve clarity. It also offers Wordtune Read, a summarization tool for long documents. Built by one of the leading AI research companies, Wordtune focuses on enhancing existing writing rather than generating content from scratch.
