What is grammar correction software?

A grammar correction software scans your text for all types of writing mistakes: grammar, punctuation, typos, misspellings, and any other issues related to sentence structure. In addition to ensuring grammatical correctness, some software is also sophisticated enough to evaluate tone, style, and syntax. Others, like Grammarly, also have a built-in checker to ensure that your writing is 100% unique!

How does it work exactly?

Most sophisticated grammar correction software like Grammarly and ProWritingAid uses a combination of rules, patterns, artificial intelligence techniques like machine learning, deep learning, and natural language processing to help improve your writing. NLP involves training a machine to perform specific tasks, just like how you teach a child new things by showing examples. Over time, these machines will understand and process human language and perform functions like scanning our text for grammatical errors, spelling mistakes, providing contextual guidance, and more. Unfortunately, most of these grammar correction tools are not open-sourced, so we can't examine how the algorithm works. Not that it matters. The good news is, we don't have to know any AI mumbo-jumbo to make good use of these grammar-checking tools!

Okay, but how does it help check my grammar mistakes?

Grammar correction software can check your work for any writing gaffes in a Word document, email, MS Word, using a browser plugin, or online forms. You can also write directly on the app itself, and the software will identify grammar issues and mistakes on the fly. Depending on which tool you use, you know something needs correction when you see some text highlighted or underlined. The grammar correction software will then display suggestions or fixes that you can accept or reject. It's that easy!

What features should I look for in grammar correction software?

Choosing the best grammar correction program can be a daunting task, especially if you're unsure where to start. Since it will be a major addition to your writing arsenal, it should be able to catch almost all of the grammar errors. In addition, your chosen software must also have the following features:

• Spelling and punctuation checker
• Plagiarism checker
• Tone and style detector
• Overused words and passive voice detection
• Word order and type correction
• Writing analysis reports
• Contextual guidance
• Built-in integrations and extensions
• Multi-platform support
