Wordtune (wordtune.com) is an AI-powered writing assistant developed by AI21 Labs that focuses on helping writers rephrase, refine, and improve existing text rather than generating content from scratch. It analyzes the context of your writing and suggests multiple alternative versions of sentences — adjusting tone, length, formality, and clarity — while maintaining your original meaning. Wordtune integrates directly with Google Docs, Microsoft Word, and any website via Chrome extension.
How Wordtune Works
You highlight a sentence or paragraph in your document or browser. Wordtune instantly generates multiple rewritten alternatives, each varying in tone, structure, or length. You select the version that fits best, or keep refining. The Expand feature adds depth to short ideas; the Shorten feature removes unnecessary words. Ask AI provides a built-in assistant for brainstorming and quick prompts. The Summarizer condenses long articles, YouTube videos, and PDFs into key points.
