Wordtune
AI paraphrasing tool that rewrites, summarizes, and refines English writing.
Wordtune is the best dedicated paraphrasing and summarization tool under $10/mo. Its Unlimited plan at $6.99/mo annual offers outstanding value. However, it's not a full Grammarly replacement for deep grammar checks and plagiarism detection. For rewriting and summarizing, it's arguably the best dedicated tool.

About Wordtune
Wordtune is an AI-powered writing assistant from AI21 Labs that helps users paraphrase, rewrite, summarize, and polish English text. It offers contextual rewrite suggestions, tone switching between formal and casual, grammar and spelling correction, and AI-powered text generation. The tool also includes a summarizer for articles, documents, and YouTube videos, a humanize AI feature to make AI-generated content sound natural, and translation from 10 languages to English. Wordtune’s fact-checking verifies claims against at least five sources. With over 10 million users and a 4.7/5 Chrome extension rating, it integrates with browsers and popular apps. Plans range from a free tier (10 daily rewrites) to an Unlimited plan at $6.99/mo billed annually, making it a cost-effective choice for light and heavy users alike. While it excels at rewriting and summarizing, it lacks deep grammar style checks and plagiarism detection compared to full-featured tools like Grammarly, but for dedicated paraphrasing and summarization, it offers exceptional value.
Behind the Verdict
Wordtune fills a specific niche: polishing English text through rewriting, summarizing, and tone adjustment. We'd reach for it when we need to rephrase a paragraph quickly, shorten a verbose email, or get a summary of a long article or YouTube video. It's particularly helpful for non-native speakers who want to sound more natural. The free tier is generous enough for light use. Where it bites: it's English-only for output, and its grammar checking is more basic than Grammarly's. Also, there's no built-in plagiarism checker. Compared to Grammarly, Wordtune is better at rewriting and summarizing but weaker at comprehensive grammar/style checking. If you mainly need to rephrase and trim text, Wordtune wins on price and focus. If you need a full grammar workout, Grammarly is still the choice. In practice, we've found the Unlimited plan at $6.99/mo (billed annually) to be a steal — it removes all rewrite and summarization limits, plus includes vocabulary and clarity improvements. Just be aware you're getting a specialized tool, not a Swiss Army knife for writing.
