Wordtune is an AI-powered writing and reading assistant developed by AI21 Labs. Its central function is rewriting: you select a sentence and receive several alternative versions, which can be made shorter, longer, more formal or more casual. A grammar checker flags spelling and grammatical mistakes and proposes corrections, while generative commands continue a paragraph, explain a point further, add a conclusion or offer an opposing view. The summariser condenses documents, articles, web pages and YouTube videos. Wordtune writes only in English, but it can translate into English from languages such as Spanish, French, German, Portuguese, Russian, Arabic, Hebrew, Hindi, Korean and Mandarin. It is available on the web, as Chrome and Microsoft Edge extensions and on iOS. Plans consist of a free Basic tier with daily limits and two paid tiers, Advanced and Unlimited, each with a three-day trial. ## Key features - **Rewrite Suggestions**: Returns a list of alternative wordings for a selected sentence that fit its context. - **Tone Switching**: Moves a sentence between casual and formal registers with one click. - **Grammar and Spelling**: Marks errors as you write and proposes other ways to phrase the sentence. - **Generative Commands**: Continues your text, expands an explanation, stresses a point or adds a closing paragraph. - **Summaries**: Shortens long documents, articles and YouTube videos into the main points. - **Translation into English**: Converts text written in a number of other languages into natural English. ## Use cases - **Polishing Emails**: Rephrase a message so it reads clearly before sending. - **Essay Editing**: Lengthen or shorten passages to fit a word count and restate sources in your own words. - **Writing in a Second Language**: Draft in your native language or rough English and get fluent English back. - **Research Triage**: Summarise articles to decide which deserve a full read. - **Social Captions**: Generate several versions of a caption and pick one. ## Things to know - **Output is English only**: Wordtune can read several languages for translation, but everything it writes is in English. - **No refunds**: The plans page says refunds are not offered; cancelling stops the next charge. - **Trial needs payment details**: The three-day trial asks for a payment method, and billing starts when the trial ends unless it is cancelled. - **Free tier is capped**: The Basic plan limits rewrites and AI suggestions per day and summaries per month. ## FAQs ### What is Wordtune?
