Wordtune
The rewriting companion from AI21 Labs: pick from several phrasings per sentence, never generates from scratch.
Wordtune is built by AI21 Labs as a rewriting companion rather than a content generator, and that framing is the whole point. You write the sentence, highlight the clunky part, and it hands you five or ten ways to say the same thing in different registers, shorten, expand, formal, casual, rather than producing a paragraph you did not author. That makes it closer to a clarity engine than to a humanizer, which is exactly why it earns a place here: a large share of people searching for a humanizer actually have a readability problem, and Wordtune is one of the few tools that fixes prose without chasing a detector score. The free tier covers 10 rewrites and Spices per day with no cost, and Premium sits around 9.99 to 13.99 dollars a month depending on billing, with Unlimited at 19.99 removing the daily cap. It runs as a browser extension across Gmail, Google Docs and LinkedIn, plus web and mobile apps. The honest limitation is scope: it works best sentence by sentence, it is English-only for rewriting, and it will not restructure a whole argument for you, so treat it as precision editing, not a draft launcher. Used that way, it is one of the most genuinely useful tools on this page.
