Sentence Rewriter: Rephrase Your Content with AI Editor

April 26, 2024

Leveraging AI for copy editing, grammar checking, and sentence rewriting has become increasingly popular to navigate the fast-paced and competitive world of content creation. 

While AI cannot fully replace human expertise, its integration into the writing process has proved to be invaluable as it has helped bloggers save 30% of their total time spent in writing.

This is because, as part of the content creation process, AI swiftly detects and rectifies errors while providing instant suggestions, which helps consistently create high-quality content that keeps readers engaged. This blog explores the pivotal role of AI in copy editing and grammar checking. 

Understanding AI-Powered Copy Editing and Grammar Checking

One of the most important branches of AI is natural language processing (NLP). NLP helps machines understand and process human language so that repetitive tasks can be automated. It facilitates data interrogation using text or voice in everyday language.

For example, NLP is the core technology behind virtual assistants like Siri and Alexa. When you ask questions to these assistants, NLP helps them understand the user's query and give answers in natural language. 

NLP combines computational linguistics, i.e., the rule-based modeling of human language, with statistical and machine learning techniques. This enables computers and digital devices to comprehend, interpret, and produce text and speech. 

For example, in sentiment analysis training, a machine learning algorithm reads a dataset and produces a model in which the sentences are inputs, and their sentiments are returned. Based on such training, machine learning makes predictions by generalizing over the dataset examples. This helps in accurately understanding the ambiguous human language.

Thus, machine learning is the driving force behind natural language processing as it teaches computer systems to recognize patterns from a dataset. In the case of grammar checking, this is the process that takes place:

  1. The text is broken down into small parts known as tokens. 
  2. Individual words are identified and assigned their respective parts of speech, like nouns, adjectives, and pronouns.
  3. Complete sentences are checked to ensure they make sense and are grammatically accurate. 
  4. If any grammar inconsistencies are found, they are pointed out, and corrective suggestions are given. The grammatical rules are already a part of the NLP library.

This process also helps AI tools become sentence rewriters. Advanced writing tools like Grammarly, Hemingway Editor, Markov Copy Editor, and Quillbot use this technology. 

Key Features of AI-Based Grammar Checkers

The key features of AI-based grammar checkers that will enable you to effortlessly enhance your writing are:

1. Contextual Grammar Analysis

In contextual grammar analysis, AI-based grammar checkers go beyond spell-checking by using contextual analysis of the text to ensure that your content is not just grammatically accurate but also makes sense in the context in which it is used.

Thus, errors related to subject-verb agreement, tense, punctuation errors, word usage, and sentence structure are identified. Suggestions are then provided to correct these errors. 

For instance, "Walking the dog tired me out" is grammatically correct, but the context suggests it wasn't the act of simply being "walking" that caused tiredness, but rather the action of "walking the dog" (the entire activity).

2. Style and Tone Recommendations

Grammar checkers are involved not only with correcting your errors but also in improving your writing style. These tools provide actionable suggestions to enhance the overall tone of your content by providing feedback on sentence structure, word choice, and style and tone inconsistencies. They help ensure that your content correctly resonates with your audience. 

For instance, "We need that report by tomorrow" sounds direct and might not be the most appropriate if you need to come across as polite. An AI tool will recommend a change in tone and phrase the same sentence like—"Would it be possible to have the report completed by tomorrow, please?"

3. Plagiarism Detection and Citation Assistance

AI-based grammar checkers also have features of real-time plagiarism detection and citation assistance. They help identify duplicate content, where it is duplicated from, and the percentage of duplication.

This helps you remove plagiarism, increase your percentage of unique content, and properly attribute authorship to already published content on the books, the web, research papers, news sources, and more.

Additionally, they also help in creating accurate citations for duplicated content and ideas. 

Popular AI Copy Editing Tools

The top four popular AI-powered copy editing tools that you can leverage to enhance your writing are:

1. Grammarly

Grammarly is an AI-assisted writing enhancement tool that offers detailed feedback on grammar, punctuation, clarity, sentence structure, engagement, and delivery.

Implementing AI in Your Writing Process

Writers cannot always produce grammatically correct and error-free content. Editing and proofreading are thus vital steps in the content writing workflow.

While human editing requires more time and leaves you open to errors being missed, AI-powered tools are a boon that quickly catches and corrects errors, boosting your overall writing quality. 

The benefits of integrating AI tools in your writing workflows are:

  • Helps in proper keyword placement throughout the content
  • Saves resources by automating content editing and sentence rewriting
  • Maintains consistency in style, tone, and formatting
  • Enhances your writing with alternative suggestions
  • Identifies plagiarism
  • Personalizes content as needed
  • Optimizes content for search engines
  • Offers real-time collaboration opportunities 

With AI-powered tools, you will receive real-time suggestions, corrections, and feedback. This facilitates immediate adjustments and improvements, retaining the content quality and ensuring effective communication with readers.

However, AI-powered tools cannot completely replace human editors as they are known to display errors and irregular inconsistencies. Each AI-powered tool also comes with its own set of limitations that are covered by human editors.

Lastly, the quality of the content depends not on AI's copy editing, grammar checking, and sentence rewriting skills but rather on the inherent quality of the original content.

Thus, AI's primary role is to free editors from repetitive, mundane tasks so that they can focus on creative and innovative tasks. 

Challenges and Considerations

Leveraging AI for copy editing and grammar checking involves some key challenges and considerations. Let's examine them.

Limitations of AI Copy Editing

While using AI for copy editing has several benefits, it also has its own set of limitations. These are:

  • AI algorithms find it challenging to engage in innovative and creative thinking, which is a must for copy editing.
  • To ensure that the content resonates with readers, it must have a human touch that makes it relatable and personal. AI copy editing lacks this. 
  • AI copy editing often leads to a lack of understanding of context, leading to inappropriate and irrelevant content. 
  • AI copy editing often results in inaccuracies, errors, and confusing phrasing, which human writers can catch during thorough proofreading.
  • AI fails to use metaphors and analogies while writing copy, which makes the content less engaging for readers.

Balancing Human Input with AI Recommendations

It is crucial to understand that AI is a supporting tool and not a replacement for writers and editors. To balance human input with AI recommendations:

  • Ensure that humans check AI-generated content and recommendations to maintain the desired tone, quality, and brand alignment. 
  • Make sure AI is used only for repetitive tasks like grammar checks and sentence rewriting, leaving creative, brand-specific tasks for humans. For instance, only humans can add metaphors to the copy. 
  • Use AI recommendations only to enhance your writing. Do not let them replace human insights, storytelling, and creativity. This ensures that your content is accurate, authentic, and engaging for readers. 
  • To align the AI tools with your company's brand voice and content standards,  continuously give it feedback and new data for training.
  • Ensure that AI recommendations do not overpower human empathy, experiences, and emotional intelligence. This will ensure powerful content that resonates with readers.  

Ethical Use of AI in Writing

AI should be a tool to enhance your writing, not replace your own critical thinking and creativity. Stay vigilant about potential biases in AI suggestions and fact-check any information generated. To ensure the ethical use of AI in writing:

  • Use AI tools only for enhancing your writing. Do not replace your writing completely with AI. 
  • Make sure you are using tools that are reliable and accurate.
  • Ensure that you understand the AI-generated content so that you can check its accuracy. Also, ensure the accuracy of AI-powered sentence rewriters, grammar checkers, and copy editors to maintain your content quality. 
  • Do not practice the usage of AI to plagiarize. 
  • To ensure that your AI tools are still accurate, regularly re-evaluate them. 
  • Check AI suggestions and feedback to ensure there are no biases. This is an important part of responsible AI usage. 
  • Stay true to your style and voice as a writer, even when using AI tools. 
  • Be honest about the usage of AI tools in your work.
