Wordtune vs HyperWrite

Wordtune, from AI21 Labs, is a sentence-level rewrite companion: highlight text, get alternative phrasings and tone shifts. Its free Basic plan allows 10 rewrites a day; Advanced is $6.99/month ($4.89 annual) and Unlimited is $9.99/month ($6.99 annual). HyperWrite is a broader writing assistant plus browser agent, with real-time research and citations; its Premium plan is $19.99/month ($16 annual) for 250 AI messages a month. If your draft already exists and you only need better phrasing, Wordtune is cheaper and simpler. If you need research, autocomplete and browser workflows alongside writing, HyperWrite is the wider tool. There is no measured quality winner in this review.

Decision pointWordtuneHyperWrite
Best suited toWriters who need to refine existing sentences or paragraphs, summarize a webpage or PDF, or ask follow-up questions about a draft.People who want help drafting or revising text in the browser, responding to routine emails, or using a cited research prompt as a starting point.
Plans and costBasic is a free plan with 10 rewrites or AI suggestions per day and 3 AI summaries per month. Paid plans offer a 3-day trial that requires payment information; the pricing page uses $ signs and says prices may vary by region or promotion, without explicitly identifying USD.The free account is limited to monthly credits on basic AI. The official page separates monthly billing from annual billing and shows lower annual-billed monthly equivalents, but uses $ without explicitly labeling the ISO currency as USD, confirm the billing currency and current price before purchase.
LimitationsThe free plan has daily rewrite and monthly summary limits. Wordtune's help page says most rewrite and generative outputs are currently only promised in English, even when the input is in another language.Free accounts have limited monthly credits, but the reviewed page does not give the free allowance amount. Source links and citations still need checking; Premium lists 250 AI messages per month and Ultra lists unlimited messages.

Use the same input

Take a rough 300-word blog paragraph and polish it for clarity and tone, then use the same tool to check one factual claim that needs a web source.

What a successful result must preserve

The tool must offer multiple rewrite options for a selected sentence, and support looking up real-time information or citations for a factual claim.
