What it really is

Wordtune — AI writing assistant for rephrasing, tone adjustment, and summarization.

Our take

Wordtune (by AI21 Labs) is a mature AI writing companion that goes well beyond simple grammar checks: it offers contextual rephrasing, formal/casual tone switching, AI summarization of texts and YouTube videos, and translation from 10 languages into English. The DB entry price of $9.99 reflects the Unlimited plan; the actual paid entry point is the Advanced plan at $6.99/mo. The DB category 'Chrome Extensions & Browser Tools' undersells it — Wordtune is a full-suite writing assistant with iOS, desktop, and deep integrations into Gmail, Slack, and Word.

Why we rate it

Wordtune's rephrasing engine stands out for preserving the writer's original meaning and voice — it doesn't just swap synonyms. The seamless browser extension experience and cross-platform reach (Gmail, Slack, Word, iOS) make it genuinely embedded in daily workflows rather than a tab-switching afterthought.

The catch

Free tier is very limited (10 rewrites/day), the 3-day trial requires payment details upfront, and deep grammar/punctuation correction still lags behind dedicated proofreaders like Grammarly.

Best for
Professionals rephrasing emails and reports for clarity and tone
Students who need to paraphrase academic material without losing meaning
Content marketers adapting copy across formal and casual registers
Not good for
Users needing deep grammar and punctuation correction (Grammarly is stronger here)
Teams requiring robust plagiarism detection as a core feature
Writers who work exclusively outside the supported browser and app ecosystem
Friction report
Time to value
Fast: install the Chrome extension, sign up free, and get AI rewrites inline in under 2 minutes.
Scale breakpoint
Per-seat Teams plan costs accumulate beyond 10 users; Unlimited plan suits solo power users better than growing teams.
Walled garden
Moderate: suggestions and summaries stay in-app; text exports easily but learned preferences and history are not portable.
