Grammar Check for Different Writing Types

Students can check essays, research papers, and dissertations for grammar errors, run-on sentences, and passive voice before submission. The tool catches subject-verb agreement errors and misplaced modifiers that spell-checkers miss entirely.

Professional Emails

Polish business emails and cover letters before sending. The tool identifies informal language, unclear phrasing, and punctuation errors that can undermine your professional credibility in workplace communication.

Non-Native English Speakers

ESL writers benefit greatly from grammar checking — the tool explains each error and suggests the correct phrasing, making it an active learning tool that helps improve English proficiency over time.

Blog Posts & Content Writing

Content writers can check articles for clarity, style consistency, and grammar before publishing. Blue highlights flag style issues like unnecessarily complex sentences that reduce readability and SEO performance.

Frequently Asked Questions

What grammar rules does this tool check?

The tool uses LanguageTool which checks hundreds of grammar rules including subject-verb agreement, article usage (a/an/the), punctuation errors, commonly confused words (there/their/they're, your/you're), double words, comma splices, and more. Style issues like overly complex phrasing are shown in blue rather than red.

How many languages are supported?

Over 20 languages are supported including English (US/UK/AU/CA/NZ/ZA), Spanish, French, German, Italian, Portuguese, Russian, Polish, Dutch, Ukrainian, Greek, Japanese, Chinese, and more. Set the language manually for best results, or use "auto-detect" and LanguageTool will identify your writing language automatically.

Is this a free Grammarly alternative?

Yes — this is a completely free grammar checker powered by LanguageTool. Unlike Grammarly which requires an account and charges for advanced features, this tool is free with no sign-up, no word limit per session, and supports 20+ languages. The primary difference is that Grammarly focuses on English and has more AI-powered writing suggestions.

Can I upload a document instead of pasting text?

Yes — click "Select file" to upload a .doc, .docx, or .txt file. The content is extracted and loaded into the editor automatically, then you can run the grammar check as usual. This is ideal for checking essays, reports, or articles you've written in a word processor.

Is my text sent to a server?

Text is sent to the LanguageTool API for analysis — this is required for the grammar check to work. LanguageTool does not permanently store your text. For sensitive documents such as confidential contracts or unpublished manuscripts, avoid pasting the full content into any online grammar tool.

What is the difference between grammar and spell check?

Spell check only flags words not found in a dictionary. Grammar check goes further — it catches correctly spelled words used in the wrong context ("their" vs "there"), subject-verb agreement errors, missing articles, dangling modifiers, and structural sentence problems that a basic spell-checker would miss entirely.

How do I use this for essay writing?

Paste your essay into the editor and select the correct language (e.g., English US or UK). Click "Check Grammar" and review all highlighted text. Red underlines indicate errors that need fixing — click each one to see the suggested correction. Blue underlines are style suggestions. Fix all errors, clear the editor, re-paste the corrected text, and check again until no errors appear.

Does the tool check punctuation errors?

Yes — LanguageTool checks for comma misuse, missing apostrophes, incorrect semicolon usage, double punctuation, and missing end punctuation. It also catches common punctuation-related grammar errors like comma splices (joining two independent clauses with just a comma).

Can this tool help non-native English speakers?

Absolutely — LanguageTool is particularly useful for ESL (English as a Second Language) writers. It explains each error and provides the corrected form, making it a learning tool as well as a checker. Common ESL errors like missing articles ("a", "an", "the"), incorrect prepositions, and wrong verb tenses are all detected.

What are style suggestions (blue highlights)?

Blue highlights are style improvements rather than grammatical errors. They flag things like wordy phrases ("in order to" → "to"), redundant phrasing, overly complex sentences, or repeated words within a short distance. Accepting style suggestions makes your writing cleaner and easier to read — important for both SEO readability scores and reader engagement.
