GrammarCheck.ai

GrammarCheck.ai is a writing tool that checks and corrects grammar, spelling, and punctuation. It highlights issues, suggests replacements, and offers a one-click action to fix all detected errors. The service also provides style suggestions, punctuation checking, paraphrasing, plagiarism checking, AI detection, AI humanizing, and summarizing. Its grammar tools support English in US, UK, Australian, and Canadian forms, along with Spanish, German, French, Portuguese, Italian, and Dutch. GrammarCheck.ai is available on the web and through Android, iOS, Linux, an API, and browser extensions; desktop and mobile apps are also listed. A free plan allows up to 650 words per submission. Lite is $4 a month with a 2,000-word limit, and Pro is $7 a month with a 6,000-word limit. The pricing note separately lists paid plans from $2.50/mo (annual). Guest users can submit three times per minute. The service does not offer a free trial. Its Chrome and Chromium extension sends selected text to its servers for checking and does not access other page content.

GrammarCheck.ai combines grammar correction with a range of writing and text-analysis tools. The free plan has a 650-word submission limit, while paid plans list higher limits; note that the pricing note and individual plan details present different billing information.

GrammarCheck.ai may suit students, book authors, bloggers, and non-native English speakers who want help reviewing written text. Its additional tools may also suit people looking to paraphrase, summarize, or check text for plagiarism or AI-generated content.

GrammarCheck.ai combines grammar correction with a range of writing and text-analysis tools. It best suits students, authors, bloggers, and non-native English speakers who want proofreading and related utilities in one service. The free tier is a useful starting point, but its short submission cap and the service’s text-retention practices matter for regular or sensitive work.

Overview

The core checker flags grammar, spelling, and punctuation mistakes, suggests replacements, and can apply corrections with one click. That makes it practical for cleaning up a draft, while style suggestions and separate text tools extend it beyond basic proofreading. Its strongest case is convenience across several writing tasks; writers who need to process long documents in one pass should compare the per-submission limits before settling on a plan.

Guest users can make three submissions per minute. The free plan allows up to 650 words per submission, so it works better for short passages than full-length essays or chapters. Free and guest submissions may be stored to help improve the service. Registered and premium users’ text is stored in checking history until they delete it or request deletion, and submitted text is processed by third-party AI providers, including Google Cloud AI services.

Key features

GrammarCheck.ai supports English in US, UK, Australian, and Canadian variants, along with Spanish, German, French, Portuguese, Italian, and Dutch. That range is useful for writers working across several languages, though the stated regional distinctions apply specifically to English.

Beyond grammar correction, the site offers punctuation checking, paraphrasing, plagiarism checking, AI detection, AI humanizing, and summarizing. Having these tools alongside proofreading may suit students and bloggers who regularly move between editing and text analysis. The word caps still shape the workflow: a large document may need to be divided into multiple submissions or handled under a plan with a higher limit.

The browser extension is available for Chrome and Chromium. It sends selected text to GrammarCheck.ai’s servers for checking and does not access other page content. That selection-based approach suits people who want to check text while browsing, but the text still leaves the browser for processing.

Pricing

The Free Plan costs nothing, billed monthly, and includes 5,000 credits with a 650-word submission limit. It is the sensible way to try the checker without a trial period, but short submissions make it a poor fit for routinely proofreading long drafts. The service offers no free trial; users can use its tools for free before upgrading.

Lite costs $4 a month, billed monthly, with 40,000 credits and a 2,000-word cap per submission. Lite Yearly is priced at $2.50 a year with annual billing of $30, 480,000 credits, the same 2,000-word cap, and history. The annual option lowers the stated monthly equivalent and adds history, while retaining a cap that may require splitting longer work.

Pro costs $7 a month, billed monthly, with 80,000 credits and a 6,000-word cap. Pro Yearly is $4 a year with annual billing of $48, 960,000 credits, unlimited grammar checks, and the same 6,000-word cap. Pro Monthly has the same stated monthly price, credit allowance, unlimited checks, and submission cap as the monthly Pro plan. These tiers suit frequent users who need more room per submission; the higher cap still does not mean unlimited document length.

API plans are aimed at developers integrating grammar checking into a workflow. API Tester costs $7 a month for 20,000 credits, 250 words per submission, and five requests per minute. API Basic costs $10 a month for 40,000 credits, the same 250-word cap, and 15 requests per minute. API Business costs $50 a month for 100,000 credits, 750 words per submission, and 40 requests per minute. The higher tiers buy request capacity and, for Business, a larger submission allowance; even Business remains capped at 750 words per submission.

Paid plans list 24/7 customer support. Users can also contact support through the Contact Us page or the website’s Live Chat button.

Platforms

GrammarCheck.ai is available on Android, iOS, Linux, and the web, with an API and browser extension also listed. A desktop app is offered as well. That broad spread makes it a flexible option for people who write across devices, though the extension’s documented checking flow sends selected text to the service’s servers.

Who it's for

Students, bloggers, and non-native English speakers can use the free tier for short checks, then move to Lite or Pro when the word cap or credit allowance becomes restrictive. Authors working on longer passages are better matched to Pro’s 6,000-word cap than to Free or Lite, though they may still need to break up longer chapters. Developers who need grammar checking inside another product should consider the API plans in light of their per-submission and per-minute limits.

Verdict

GrammarCheck.ai is a good fit for writers who want grammar correction plus paraphrasing, summarizing, and other text tools, especially when their work can fit within its submission caps.
