Understanding the value of automated proofreading for any writer
Real‑Time Error Detection
Your text is scanned automatically 1 second after you stop typing. Grammar, spelling, and punctuation issues are highlighted instantly, so you never lose your writing flow.
Four English Dialects
Switch between US, UK, Canadian, and Australian English. The tool adapts its spelling and style suggestions to match your chosen variant — ideal for international submissions.
One‑Click Fixes
Apply individual corrections with a single click, or use the “Fix All Errors” button to instantly clean your entire document. No manual retyping needed.
Learn While You Write
Each suggestion includes a clear explanation of the mistake. Over time, you'll internalize correct grammar patterns and become a stronger writer.

Your text is never stored, logged, or added to any database. The analysis happens in memory and results are discarded immediately — safe for confidential documents.
Save Hours of Proofreading
What used to take 20 minutes of manual proofreading now happens in seconds. Spend your time on ideas, not on hunting for typos.

Frequently Asked Questions & Troubleshooting
Quick answers to common questions and issues
Several reasons could cause zero detections:
- You have fewer than 3 words — the auto‑scan only activates with sufficient text.
- Your writing is genuinely error‑free — congratulations!
- You might be using a dialect different from the selected variant — try switching to another English variant.
- The tool works best with complete sentences; fragmented notes may not trigger grammar checks.
Yes! Select “UK English” from the variant dropdown. The tool will then expect British spellings (e.g., “colour,” “realise,” “centre”) and flag American spellings as potential errors if they conflict with your chosen variant.
Absolutely not. Your text is transmitted securely to our grammar engine, processed in memory, and the results are returned without any logging or storage. We never retain, share, or sell your content. This makes the tool safe for sensitive academic, business, or personal writing.
“Fix All Errors” applies every suggestion at once. If you disagree with a particular correction, use the individual “Apply Correction” buttons instead, and skip the ones you want to keep. You can also manually edit the text after fixes — the auto‑scan will re‑analyze any changes.
This usually means the grammar engine couldn't be reached. Check your internet connection, refresh the page, and try again. If the problem persists, the server may be temporarily overloaded — wait a minute and then continue typing; the auto‑scan will retry.
Currently, the tool is optimized for English only (with the four major dialects). Support for other languages is not yet available, but we're exploring future multilingual capabilities.
There's no hard limit, but for optimal speed, we recommend sections of up to 2000 words. Very large texts may take a few extra seconds to scan. You can always split long documents into chapters and check them sequentially.
Yes, 100% free. No sign‑up, no subscription, no usage limits. You can scan as many texts as you need, whenever you need. If you find it helpful, sharing the tool with friends or colleagues is the best way to support us.
