Punctuation Problems
Missing commas, wrong apostrophes, extra full stops – our punctuation checker finds them all.
Style & Clarity
Some sentences are technically correct but still hard to read. This cleans those up so your writing flows better. Works well for emails, essays, and reports.

How to Check Your Grammar – 3 Simple Steps
It is pretty straightforward. Paste your text, pick a writing style, and hit the button. That is really all there is to it.
Paste or Type Your Text
Copy your text and paste it into the box, or just type directly. You can also upload a .txt or .docx file up to 5MB if you do not want to copy-paste a long document.
Choose Your Writing Style
Pick the mode that matches what you are writing. General works for most things. Academic is for essays. Business is for work emails. Casual and Creative are for everything else. The right mode means better, more useful suggestions.
Click Check and Fix
Once you click check, the results appear right away. You can see every error, read the corrected version, copy it, or download it as a .txt file.

Tips to Write Better
Using a grammar checker to fix errors online is a good start – but picking up the habit of writing carefully saves you time in the long run. A few things that actually help:
If you stumble over it, your reader will too. Your ears catch what your eyes miss.
One idea per sentence is enough. Short sentences are easier to read and harder to get wrong.
Never send an email or submit an essay without reading it first. Running it through a free grammar checker takes less than a minute.
When the tool flags an error, take a second to understand why. That is how you stop making the same mistake twice.
Checking an essay? Use Academic mode. Writing a work email? Use Business mode. The right mode gives you feedback that actually fits what you are writing.
