Wordtune
AI Rewriter That Preserves Your Voice
What is Wordtune?
Wordtune is an AI rewriting and writing companion developed by AI21 Labs, focused on helping you express ideas more clearly without losing your voice. Unlike paraphrasers that swap synonyms mechanically, Wordtune actually understands meaning and suggests rewrites that improve flow, shorten verbose sentences, or shift tone between casual and formal. The Wordtune editor offers Spices, which are prompts like Continue Writing, Explain, Counterargument, and Statistical Fact to extend your draft with relevant additions. Wordtune Read, a separate product, summarizes long PDFs and articles for fast comprehension. Used by 10+ million writers, Wordtune is particularly popular with non-native English speakers and academics who want sharper prose.
