Wordtune

Wordtune doesn't try to write your essay or email for you. You write the sentence, highlight it and Wordtune offers several other ways to say the same thing: more formal, more casual, shorter or longer. You pick the one that sounds like you. It comes from AI21 Labs, an Israeli AI company, and says it has more than 10 million users.

Around the rewrite feature sit grammar and spelling checks, a tool that continues your text when you get stuck, a synonym finder and a summarizer for long articles. Wordtune writes only in English, but it can translate into English from 10 languages, which makes it especially useful for people who think in another language.

The free plan counts rewrites

The free Basic plan is enough to judge whether the suggestions suit your writing. It allows 10 rewrites and AI suggestions a day and 3 article summaries a month. Spelling and grammar corrections are unlimited.

Ten rewrites go quickly if you polish every paragraph of a report. For a few important emails a day, they last. The daily allowance resets, so a light user may never need to pay.

Advanced or Unlimited

Wordtune's plans on October 5, 2026, with the switch set to annual billing at half the monthly price.

Both paid plans start with a 3-day free trial. On yearly billing, Advanced comes to about $84 a year and Unlimited to about $120.

The gap between the two plans is small on yearly billing, $3 a month, and Unlimited removes the daily counting entirely. Advanced makes sense only if you're sure 30 rewrites a day covers you. Monthly billing doubles the price, so it's worth it only for a short project, such as finishing a thesis.

Students pay less

Wordtune offers students 30% off. You apply through a form with your university's name and a copy of a current student ID or proof of enrollment, and the discount lasts 12 months.

Wordtune's own FAQ pitches it for essays and says it adds sources to the facts it generates. Its homepage says it checks at least five sources before treating a fact as credible. That's useful for drafting, but every source still needs checking against the original before it goes into academic work.

Will rewrites trip an AI detector?

They might. Wordtune's suggestions come from a language model, so a passage rewritten sentence by sentence can read as AI-assisted to detection tools. Many universities also count AI paraphrasing as AI use, whatever a detector says. Wordtune presents paraphrasing as a way to avoid plagiarism, but rewording a source without citing it is still plagiarism. It also sells a Humanize AI tool for making AI-generated text read more naturally, and using that to pass off AI writing as your own breaks most academic integrity rules.

The safest pattern is to use Wordtune on your own sentences, accept changes selectively and keep your drafts. If you need to check a text yourself, detectors such as GPTZero or Originality.ai show how it scores.

Grammarly and QuillBot do it differently

Grammarly is the broader tool. It checks grammar, clarity and tone everywhere you type, has a strong free tier, and Pro costs $12 a month billed yearly or $30 monthly. Wordtune is narrower and cheaper, and its strength is choice: several full rephrasings of a sentence instead of a single correction.

QuillBot is the closest match as a paraphraser, with Premium at $8.33 a month billed yearly. Its Premium plan has nine paraphrasing modes plus custom ones, works in 23 languages and adds a citation generator. Wordtune's case is simplicity: highlight a sentence in your browser through its Chrome extension and pick from a handful of rewrites.

For a writer whose English is good but not native, Wordtune's translate-then-rephrase approach is the reason to choose it. Write the thought in your own language if you need to, bring it into English and adjust the tone until it sounds natural.
