Grammar checker FAQ
What does a grammar checker do?
A grammar checker looks for possible mistakes in your writing and suggests corrections. It’s AI highlights issues and offers suggested replacements where available. You can accept or dismiss them.
Is this a free grammar checker?
Yes. The free plan includes 3 grammar checks, subject to your account’s word and text limits. Your account shows your remaining allowance. Additional usage depends on your plan.
What is the difference between a grammar check and a spell check?
A spell check focuses on misspelled words. A grammar check also considers how words work together, such as verb agreement and sentence structure. It’s AI can flag spelling, grammar, punctuation, and some style issues; coverage varies by language.
Will it rewrite my text automatically?
You decide which suggestions to apply. Review corrections individually, accept a group of suggestions, or dismiss the changes you do not want. You can undo edits and copy the corrected text.
Is this an AI grammar checker?
No. Grammar correction is based on language rules and does not use AI to generate corrections or rewrite your text. You choose which suggested edits to apply. AI detection is available as a separate check.
Can I check writing in different languages?
Yes. Grammar checking detects the language of your text and supports multiple languages, including English, Arabic, German, Spanish, and French. The types and detail of suggestions vary by language.
Can I check an essay or upload a document?
Yes. Paste your essay, email, article, or other draft into the checker, or upload a PDF, DOCX, or TXT document. File and text limits depend on your account.
Does grammar checking also detect AI or plagiarism?
