Grammar Checker FAQ
Is this grammar checker free?
Yes. Check as much text as you like with no account, no word limit per day and no paid upgrade.
Is my text uploaded?
No. The checker runs in your browser and your text never leaves your device. The first visit downloads the grammar engine (about 8 MB) once; after that it starts from your browser's storage.
Which languages does it check?
English only: American, British, Australian, Canadian and Indian spelling. Text in other languages will show many false spelling suggestions.
What kinds of mistakes does it find?
Misspellings and typos, subject–verb agreement, “a” versus “an”, repeated words, commonly confused words such as their/they're and its/it's, capitalization, spacing and punctuation, plus some wordy or redundant phrases. It checks rules, so it can miss mistakes that need an understanding of the whole sentence.
Can it rewrite my text or change its tone?
Not at the moment. It suggests corrections for specific words and phrases; you stay in control of every change.
How is readability measured?
With the Flesch reading ease score (0–100, higher is easier) and the Flesch–Kincaid grade level, from sentence length and syllables per word. Most web writing aims for 60 or more.
Can I check a Word document?
Yes. Open a .docx file to check its text, then download the corrected text as .docx or .txt. Formatting such as fonts, images and tables is not kept.
Is my work saved?
Your text, the words you add to your dictionary and the suggestions you ignore are saved in this browser, so they are still there when you come back.
