Pick Grammarly if…
you want every email and document checked as you write, plus plagiarism and AI-text detection on Pro.
Grammarly is a proofreader first. It flags grammar, spelling and tone as you type, with AI rewrites added on top. Wordtune, from AI21 Labs, does the reverse: it rephrases and restructures sentences you've already written and treats grammar checks as a side feature. Neither drafts long content from scratch. Your choice depends on whether you mostly need corrections or other ways to phrase a sentence.
Pick Grammarly if you want errors and tone caught in real time; the free plan does that well. Pick Wordtune if you mostly rephrase your own sentences. Its Unlimited plan ($9.99/mo) removes the daily rewrite caps for a fraction of Grammarly Pro's $30/mo monthly price.

Wordtune. Even its Unlimited plan ($9.99/mo) costs far less than Grammarly Pro's monthly price ($30/mo), and both are cheaper when billed annually.
