Grammar, spelling, and punctuation checker with one-click fixes plus a plagiarism checker and humanizer.
Grammarcheck.ai checks text for grammar, spelling, and punctuation errors and offers one-click corrections, aimed at students, authors, bloggers, and non-native English speakers proofreading academic work, manuscripts, or blog posts. Beyond the core checker it also offers a paraphraser, a plagiarism checker, and an AI humanizer, each metered separately by a credit system, from 1 credit per word for grammar checking up to 5 credits per word for humanizing text. The free plan includes 5,000 credits a month; paid plans run $4/month for 40,000 credits or $7/month for unlimited credits when billed monthly, dropping to $2.50 and $4 a month respectively when billed yearly. The site does not name a company or location beyond its own brand.
Free plan includes 5,000 credits/month. Paid: LITE is $4/month ($2.50/month billed yearly) for 40,000 credits; PRO is $7/month ($4/month billed yearly) for unlimited core-tool credits.
Use tool ↗Grammarcheck.ai covers the basics, grammar, spelling, punctuation, plus a paraphraser, plagiarism checker, and humanizer bundled into the same credit pool. Pricing is clearly published and cheap relative to the bigger names in this space, though the credit system means heavier tools like the humanizer burn through an allowance much faster than plain grammar checking.
Watch out: Unlimited credits only apply to the PRO tier's core tools; heavier features stay credit-metered per the site's own cost table.
