Running the business
Grammarly proofreads whatever you are typing for free, spelling, grammar and tone, and adds full rewrites and a plagiarism check on Pro at $12 a month, $144 a year. Wordtune does one narrower job well: hand it a sentence and it returns alternatives, shorter, longer, more casual, more formal, for $6.99 a month billed annually, about $84 a year. Grammarly catches what is wrong. Wordtune fixes what is not wrong but reads badly.

The second pair of eyes on everything you write
Grammarly catches the mistakes that get noticed in a sponsor email or a video description, and it does it inside whatever box you are typing in rather than in a separate app. The free tier covers spelling, grammar and tone. Rewriting, plagiarism detection and the larger prompt allowance sit behind Pro.
Rewrites a sentence into ten other sentences
Wordtune is narrower than the tools that write from a brief: you give it a sentence you already wrote and it hands back alternatives, shorter, longer, more casual, more formal. That makes it useful to people who can write and get stuck, rather than to people who want a draft produced. The free plan allows a few rewrites a day and the trial on the paid ones runs three days.
Our note
The three-day trial is the shortest in this category, so decide what you want to check before starting it. What this does better than the general assistants is rewrite a sentence you already care about, which is a real and narrow use.
Pick Grammarly if you want one tool watching everything you type for actual mistakes, in a browser, a desktop app or a phone keyboard. The free plan covers spelling, grammar, tone and 100 AI prompts a month, and Pro at $12 a month, $144 a year, adds rewrites and plagiarism detection after a 7-day trial that takes no card up front.
Pick Wordtune if your sentences are already correct and just sound stiff or foreign. Advanced is $6.99 a month billed annually, about $84 a year, roughly $60 less than Grammarly Pro, and includes length and tone controls plus a browser extension. The trial is only three days, the shortest in this category, so decide what to test before starting it.

Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
