Grammar Corrector: Your Friendly Writing Helper

Grammar Corrector

Write with confidence anywhere on the web! Grammar Corrector is a simple, right-click tool that instantly fixes grammar, improves how your sentences flow, and summarizes long text. It is 100% free, with no logins, no subscriptions, and no hidden catches.

If English is your second language, or if you just worry about making spelling and grammar mistakes, this tool was built exactly for you. It takes the stress out of typing by turning your drafts into clear, polished English. Powered by Chrome’s Built-in AI (Gemini Nano), it runs completely on your own computer. This means it is lightning-fast and 100% private—your writing never gets sent to the cloud!

Key Features
100% Private & Local: Your keystrokes stay on your device. No cloud processing, no data tracking, and no subscriptions.

Three Easy Editing Modes:

Strict Grammar Check: Fixes typos and grammar mistakes while keeping your exact meaning.

Improve Flow: Makes your writing sound smooth, natural, and conversational.

Summarize: Turns long, heavy text into short, easy-to-read summaries.

Pick Your English: Choose from US, UK, Australian, Canadian, Indian, South African, New Zealand, or Irish English so your spelling perfectly matches who you are talking to.

Works Everywhere: Use it smoothly in text boxes, social media, and emails. If you use it on text you can't edit (like a news article), a clean little pop-up box will appear so you can easily read or copy the fixed text.

How to Use
If you ever feel unsure about what you just typed in a comment box or email:

Highlight the text you want to check.

Right-click on the highlighted words.

Click "Correct Grammar" from the menu.

Watch it work! The AI will instantly replace your text with a perfectly corrected version.

You can also use this to understand other people's writing better! Just highlight their sentence, right-click, and select "Correct Grammar." A small box will pop up showing you the corrected sentence or a quick summary.

Quick One-Time Setup
Because this extension uses the powerful Local AI built directly into your browser, you just need to make sure Chrome's AI is turned on. It only takes a second:

Type chrome://flags/#prompt-api-for-gemini-nano into your address bar and hit Enter.

Change the setting in the drop-down menu to Enabled.

Restart your browser. (Note: The very first time you use it, Chrome might take a few minutes to download the AI in the background. Just give it a moment!)

That's it! You are ready to write with absolute privacy and confidence today.
