Frequently Asked Questions
What types of errors does the grammar checker detect?
The tool detects spelling mistakes, grammatical errors (subject-verb agreement, tense consistency), punctuation issues (missing commas, apostrophe misuse), and style suggestions (passive voice, wordiness).
Is this grammar checker as good as Grammarly?
It covers the most common errors effectively and is completely free with no word limits. Grammarly Premium adds tone detection and plagiarism checking. For basic grammar and spelling, this tool handles the majority of use cases.
Does the tool check American English or British English?
You can select your preferred dialect. The main difference is spelling: "colour" vs "color," "realise" vs "realize." Grammar rules are largely the same between dialects.
Is my text sent to a server for processing?
Grammar analysis may use browser-side processing or an API depending on text length. No text is stored permanently. Check the privacy notice for the exact processing method.
Can the grammar checker detect AI-generated text?
No. Grammar checking and AI detection are separate tools. Use the AI Content Detector tool for checking whether text was AI-generated.
