Wordtune

What is Wordtune?

Wordtune is an AI writing tool that rewrites, improves and adjusts sentences and paragraphs while the original meaning stays intact. Instead of generating text from scratch, Wordtune helps you find the right phrasing faster for an idea that is already on paper. The tool was developed by AI21 Labs and builds on their own large language models, which specialize in fluent and natural English.

How does Wordtune work?

You select a sentence and Wordtune immediately generates multiple alternative phrasings, so you can choose which variant fits best. In doing so, the system analyzes not only the selected sentence, but also the surrounding context in the document, so the suggestions stay coherent with the rest of the text. Wordtune works as a browser extension and integrates directly into Google Docs, Gmail and LinkedIn, among others, so you don't have to leave your own work environment.

Key features

• Rewriting — multiple alternative phrasings for every selected sentence.
• Tone and length — make text more formal or informal, shorten or expand it and adjust the language level.
• AI summarizer — concisely summarize long documents.
• Co-writing feature — automatically finish sentences based on what you have already written.
• Spices — suggestions to add an example, counterpoint or statistic and make the text stronger in substance.

Wordtune versus alternatives

Where Grammarly mainly corrects grammatical errors and QuillBot paraphrases for variation, Wordtune focuses on writing quality and finding the precise nuance you mean. The spices feature has no direct counterpart in other tools and helps you write more strongly not only stylistically, but also in substance. The deep integration into Google Docs and Gmail also makes the tool less disruptive in your daily workflow.

Who is it for?

Wordtune is especially popular with professionals who write in English without it being their native language, with academics who want to polish their papers and with content creators who want to refine texts without fully rewriting them.
