Wordtune
Wordtune is AI21 Labs' AI writing assistant. The vendor describes it as "an AI-powered paraphrasing tool and reading and writing assistant that can correct spelling and grammar, switch between formal and casual tones, lengthen or shorten sentences, and generate text based on your writing style", adding that it can also summarize documents, articles, webpages and YouTube videos. It runs as a web app, a Chrome extension, a Microsoft Edge extension and an iOS app. The free Basic plan allows 10 rewrites and AI suggestions per day and 3 AI summarizations per month, with unlimited spelling and grammar checks; paid Advanced and Unlimited plans raise or remove those caps.
