About Grammar Checker

This basic grammar checker uses rule-based pattern matching to detect common writing errors. It runs entirely in your browser and does not send your text to any external server.

What It Checks

Frequently Asked Questions

Is this better than my browser's spell checker?
This tool complements your browser's spell checker by also detecting grammar and style issues like passive voice, double spaces, and capitalization errors that browsers typically do not flag.
Why does it flag passive voice?
Passive voice is not grammatically incorrect, but active voice is generally clearer and more direct. The tool flags passive voice as a style suggestion, not an error. You can choose to keep passive voice when it suits your writing style.
Can it fix errors automatically?
This tool highlights and describes errors but does not auto-correct them. Review each suggestion and make changes manually in your original text to ensure accuracy.
