Wordtune is an AI rewriting tool from AI21 Labs that suggests alternate phrasings for any sentence — shorter, longer, casual, formal — directly inside Google Docs, Microsoft Word, Gmail, and almost any browser textarea via its Chrome extension. It's a sentence-level co-pilot, not a story generator.

## What You Get

- **Rewrite suggestions:** Highlight a sentence and get 5-10 alternative phrasings; choose tone (casual, formal) and length (shorter, longer).
- **Browser extension:** Works in Google Docs, Microsoft Word online, Gmail, Slack, LinkedIn, and most rich-text fields.
- **Wordtune Spices:** Generate explanations, examples, counter-arguments, or definitions to expand thin passages.
- **Read mode:** Summarize PDFs and long articles for research use.
- **Mobile apps:** iOS and Android keyboards bring rewriting to phone writing.

## Pricing

- **Free:** 10 rewrites per day, basic features
- **Plus / Premium:** $6.99–$9.99/mo (annual billing) — unlimited rewrites, advanced tones
- **Premium for Teams:** Higher per-seat pricing
- Annual billing required for the lowest rates; monthly billing is materially more expensive.

## Strengths

- **Tight integration everywhere:** Works in Google Docs and Word without copy-paste — a major workflow advantage.
- **Free tier is actually useful:** 10 rewrites/day covers casual use without forcing an upgrade.
- **Faster than ChatGPT for sentence work:** Inline suggestions appear in 1-2 seconds vs. switching tabs to a chat UI.

## Limitations

- **Sentence-level only:** Wordtune does not generate scenes, plan plots, or maintain story context — it's the wrong tool for novel drafting.
- **No fiction tuning:** Suggestions skew toward business and academic prose; literary voice is often flattened.
- **Not a grammar checker:** Doesn't catch typos or grammar errors — pair with Grammarly or ProWritingAid for proofreading.
- **Daily caps on free:** 10 rewrites/day is fine for occasional polish, restrictive for full-manuscript revision.
