Grammar Checker – Free Online Grammar & Spelling Checker
About the Grammar Checker
The Grammar Checker scans your text for grammar, spelling, and style issues and highlights every problem directly in your writing. Click any highlighted word or use the “Apply” button next to each issue to instantly accept a suggested correction, then compare your original and fixed text side by side.
It supports eight English and European language variants, including English (US, UK, Australia, Canada, New Zealand), French, German, and Dutch, so you can check text in the dialect that matches your audience. Before running a check, the Word Counter helps you confirm your text fits within the tool’s word limit, and afterward the AI Detector can screen your writing for AI-generated patterns, while the Case Converter helps clean up letter casing before final publishing.
The BigToolSite Team tested this checker across all eight supported languages, short and long-form text samples, and multiple simultaneous corrections to confirm suggestions apply accurately without breaking sentence structure.
How to Use the Grammar Checker
- Select your Check Language from the dropdown (English variants, French, German, or Dutch).
- Paste or type your text into the input box.
- Watch the live word counter to stay within the per-check word limit.
- Click Check Grammar to scan your text for issues.
- Review each highlighted issue, click Apply to accept a suggestion, or click directly on a highlighted word.
- Use Copy or Download to save either your original or fully corrected text.
Example Usage
Input: “She dont like to check her grammar before she publish her work.”
Output: The tool flags “dont” and suggests “doesn’t,” and flags “publish” and suggests “publishes,” letting you apply each fix individually or review them all before copying the corrected text.
This side-by-side view makes it easy to see exactly what changed, which is especially helpful when proofreading longer articles or emails before sending.
