Wordtune
AI writing assistant that rewrites, shortens, expands, and adds context to sentences - used by 10M+ writers.
Wordtune is an AI writing companion from AI21 Labs built around one core insight: good writing comes from rewriting. Rather than generating content from scratch, Wordtune takes your existing sentences and suggests better phrasing, shorter alternatives, expanded versions, or tone adjustments. The Spices feature adds value by inserting relevant examples, statistics, and explanations into your draft. Wordtune Read summarizes long documents and articles. The Chrome extension works inside Gmail, Google Docs, LinkedIn, and any web text field - making AI writing assistance available everywhere without leaving the current tool.
