What is Wordtune?

What it is

Wordtune is an AI writing assistant from AI21 Labs that rewrites sentences and paragraphs, suggests clearer or more formal wording, summarises documents and checks spelling and grammar. It works in its own editor and through browser integrations, and is aimed at people polishing text rather than generating it from scratch.

Key features

Rewrite suggestions for any sentence or paragraph (casual, formal, shorten, expand)
AI suggestions for vocabulary, clarity and fluency
Summarizer for articles, PDFs and documents
Unlimited spelling and grammar checks on every plan
Paraphrasing for articles, essays and emails
Premium support on Unlimited

Models inside

Wordtune does not publish which models power it (AI21 Labs builds its own Jamba models, but Wordtune's pages do not say what it runs), so none are listed.

Pricing and rights

As of September 2026: Basic (free) gives 10 rewrites and AI suggestions a day, 3 summaries a month and unlimited spelling and grammar checks. Advanced costs $6.99/month ($4.89/month billed annually) with 30 rewrites a day and 15 summaries a month. Unlimited costs $9.99/month ($6.99/month billed annually) with unlimited rewrites, suggestions and summaries. The pricing page does not describe output rights; check Wordtune's terms if you rewrite client material.

Who it is for

Non-native English speakers, students and professionals who want quick alternatives to awkward sentences and short summaries of long reading. It is also a light add-on for writers who already draft with another tool and only want a quick way to vary phrasing or cut wordy sentences. Because limits are counted per day, occasional users can stay on the free plan for a long time, while daily users will want Unlimited.

Verdict

Wordtune is inexpensive and good at sentence-level rewording. Free limits are tight, it has little for teams or brands, and it does not replace a full AI writer for drafting whole pieces.
