Description
Wordtune is a writing assistant built by AI21 Labs around rewriting rather than only correcting. Select a sentence and it proposes alternatives that keep the meaning, can make the wording more formal or casual, shorter or longer, and fixes grammar and spelling as you type. It also generates new copy from a prompt, "humanizes" stiff AI-written text, and summarises long articles, documents and YouTube videos.
It works in a web editor, as a browser extension across the sites you already write in, and as an AI writing keyboard for iPhone that brings rewrites and corrections into any app.
The free Basic plan includes grammar and spelling checks with 10 rewrites and AI suggestions a day. Advanced (.99 a month, or .89 billed annually) raises the daily limits, and Unlimited (.99 a month, or .99 billed annually) removes them; both paid plans start with a 3-day free trial, and business plans add SAML SSO and centralised billing.
