Wordtune

What is Wordtune?

Wordtune is an AI writing assistant built by AI21 Labs that specializes in sentence-level rewriting. Unlike tools that focus on grammar correction or long-form content generation, Wordtune's core strength is helping you express existing ideas more clearly, concisely, or with a different tone. You select a sentence, and Wordtune generates multiple alternative versions that convey the same meaning with improved clarity, different formality levels, or adjusted length. This makes it particularly valuable for non-native English speakers, professionals refining business communications, and anyone who knows what they want to say but struggles to find the right words.

The rewriting engine offers several distinct modes. The standard rewrite generates alternative phrasings that improve clarity and flow. Casual and formal tone adjustments let you quickly shift the register of your writing to match the context — making an email less stiff or a report more professional. The expand feature adds detail and context to terse sentences, while the shorten feature condenses verbose passages into more concise alternatives. Each mode generates multiple suggestions, allowing you to pick the version that best captures your intended meaning and voice.

Wordtune Read, the platform's summarization feature, extends the tool beyond writing into reading efficiency. It can summarize articles, PDFs, and YouTube videos, extracting key points and enabling you to quickly digest long-form content. This is particularly useful for researchers, students, and professionals who need to process large volumes of written and video content. The YouTube summarization feature is especially notable — paste a YouTube URL and get a structured summary of the video's key points, saving you the time of watching the entire video.

The tool integrates into your workflow primarily through a browser extension that works across Gmail, Google Docs, LinkedIn, Twitter, Slack, and most web-based text editors. The extension provides inline suggestions as you type, making it feel like a natural part of your writing process rather than a separate tool you need to switch to. While Wordtune's free tier limits you to 10 rewrites per day, it provides enough usage to evaluate whether the AI-powered suggestions genuinely improve your writing before committing to a paid plan.
