What is Wordtune?

Wordtune is an AI writing assistant developed by AI21 Labs that specializes in text improvement. Its core function is rewriting existing text into clearer, more compelling expressions, providing real-time suggestions for tone changes (casual/formal), sentence shortening/expansion, and paraphrasing. A long-text summarization feature can concisely summarize articles, PDFs, and YouTube video content. It integrates with major platforms including Google Docs, Gmail, Microsoft Word, Slack, and LinkedIn, allowing you to receive AI writing assistance without leaving your usual work environment. Rather than generating text from scratch, it is positioned as a tool for polishing text you've already written, making it particularly popular among writers and editors.
