GrammarCheck.ai

Overview

GrammarCheck.ai combines grammar correction and style suggestions with a collection of other writing tools. It suits students, book authors, bloggers, and non-native English speakers who want proofreading plus utilities such as paraphrasing or summarizing. Its main appeal is breadth at a low entry price; its limits on submission size and the handling of submitted text deserve attention.

Key features

The checker flags grammar, spelling, and punctuation mistakes, proposes replacements, and offers a one-click “Fix All Errors” action. That makes it useful for a quick cleanup of a draft, while style suggestions can prompt a broader edit. Writers should still judge whether proposed changes preserve their intended meaning and voice.

GrammarCheck.ai supports English in US, UK, Australian, and Canadian variants, as well as Spanish, German, French, Portuguese, Italian, and Dutch. The additional tools include punctuation checking, paraphrasing, plagiarism checking, AI detection, AI humanizing, and summarizing. This range can cover several common writing tasks in one service, though the per-submission caps may be restrictive for longer documents.

Guest users can make three submissions per minute. The Chrome and Chromium extension sends selected text to GrammarCheck.ai’s servers for checking and does not access other page content. Checked text may be stored for free and guest users to help improve the service; registered and premium users’ text is stored in checking history until they delete it or request deletion. Submitted text is processed by third-party AI providers, including Google Cloud AI services, so writers handling sensitive material should consider those terms before submitting it.

Pricing

The free plan costs nothing and includes 5,000 credits with a 650-word submission limit. It is a practical way to try the tools or proofread short pieces, but not a fit for longer drafts. There is no free trial; tools can be used for free before upgrading.

Lite Monthly costs $4 a month and includes 40,000 credits, a 2,000-word submission limit, and history. Pro Monthly costs $7 a month and includes 80,000 credits, unlimited grammar checks, and a 6,000-word limit. Lite is the lower-cost step up for regular shorter work; Pro better fits frequent checking or longer submissions.

Lite Yearly costs $2.50 a year, billed yearly at 30 USD, with 480,000 credits, a 2,000-word limit, and history. Pro Yearly costs $4 a year, billed yearly at 48 USD, with 960,000 credits, unlimited grammar checks, and a 6,000-word limit. The annual plans lower the stated monthly rate while retaining the same submission limits as their monthly counterparts.

API access is priced separately: 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, 250 words per submission, and 15 requests per minute; API Business costs $50 a month for 100,000 credits, 750 words per submission, and 40 requests per minute. These plans are aimed at API use, with request and word caps that matter for integration workloads.

Paid plans list 24/7 customer support. The pricing FAQ also directs users to the Contact Us page or Live Chat for support. No seat counts are stated, so the plans are best assessed as individual usage tiers.

Platforms

GrammarCheck.ai is offered on the web and has Android and iOS apps, a browser extension, a desktop app, and API access. The platform list also includes Linux. The extension’s selected-text behavior makes it a convenient option for checking passages in the browser, subject to its server processing and text-retention practices.

Who it's for

Students, authors, bloggers, and non-native English speakers are the clearest audience for the core checker. The free tier works for brief submissions, while paid plans suit writers whose work regularly exceeds 650 words. The broader set of writing utilities may also appeal to people who want proofreading and text editing tools under one service. Those working with confidential drafts should weigh the text-storage and third-party processing terms.

Pros and cons

• Pros: Corrections cover grammar, spelling, and punctuation, with replacement suggestions and a one-click fix option.
• Pros: Multiple supported languages and additional tools extend its use beyond basic proofreading.
• Pros: Paid tiers raise the per-submission limit to 2,000 or 6,000 words, and annual plans include substantial credit allowances.
• Cons: The 650-word free submission cap is limiting for full-length drafts.
• Cons: Even Pro caps a submission at 6,000 words; users with longer documents may need to split their text.
• Cons: Free and guest text may be retained to improve the service, and submitted text is processed by third-party AI providers.

Verdict

Choose GrammarCheck.ai if you want multilingual grammar and punctuation correction, style suggestions, and several extra writing tools, with paid plans for larger submissions. The free plan gives you a way to start, but its 650-word cap makes it a poor fit for long drafts; choose another service if local text processing or a French-focused checker better matches your priorities.
