Neural networks that have been taught how to do a paraphrase are digital editors that utilize sophisticated models (e.g., BERT and GPT-5.5). In simple terms, this means that the algorithm no longer merely rearranges the words in a piece of writing as was done with the old synonymization programs. Instead, it analyzes the surrounding text for its context (“understanding” how sentences relate) and then provides a new version while retaining the original's intent.

Generative AI creates a new structure (and possibly style) for each piece of text it analyzes. For example, it may be able to replace a more formal, technical writing style (that could be considered “dry”) with one that conveys more emotion and thus is more engaging for the reader. In many cases, a good neural network can produce a rewritten version of a thought that is difficult to tell apart from what a person would write, due to its emphasis on meaning rather than just looking to substitute dictionary definitions for equivalent words.

“After conducting 43 different tests over 8 years, we have concluded that if your content automation does not include AI, then it will no longer be feasible to compete against the large players in this industry. Although the speed of creation has improved by 6 times, the machine will also make an error every 3rd attempt unless it undergoes human editing.”

How Paraphrasing Algorithms Utilizing AI Work

Using the old approach to synonymizing, synonym generators worked by taking a set of words and matching each one to a similar word found on a predefined list. There was no analysis. This is how the phrase “the client signed the contract” could become “the buyer scrawled on the contract,” even though this may refer to a legal entity signing with an electronic signature. Neural networks that are built with transformer architecture (i.e. BERT and GPT-4/5) translate words into sets of numerical codes. They understand the relationship between those codes. The details about the system's understanding of signed contracts as a common legal term causes it to offer the user an alternate term or phrase such as "executing an agreement". AI determines the tone for each respective use by viewing the context of numerous sentences around the specific use of that word.

“The accuracy of maintaining meaning when rewriting is 40-60% better with a transformer model over using a dictionary.”

Neural Networks Help with Intelligent Word Replacement in Text

Using a neural network to replace individual words within a block of text while keeping the meaning intact while changing the style is a much smarter approach than what the AI tool does now. A generative model does not search for individual words or synonyms in a static way; it develops the new sentence based on the patterns learned while controlling for the appropriateness of the individual words being replaced. For example, rather than sending an informal message such as "the marketing guys put up an ad", the word system would rephrase it into "the specialists in that department initiated a campaign". The system selects the vocabulary used based on the same tone.

Example:

  • Original text: We asked customers to provide feedback about our product so we would know what is attractive to our customers.
  • Transformed text after AI processing: We conducted a user survey of our customers, to collect data on their functional preferences for the technology solution.

The original text sounds informal and friendly. The second is written as a formal business document and the AI is programmed to recognize the difference in the tone and thus rewrite accordingly.

How does AI rewrite entire paragraphs?

With regard to rewriting larger chunks of content, the paragraph rewriting neural network operates from a macro perspective. The system identifies a chain of all the main concepts within the whole text, to be reorganised into a new conceptual chain, whilst maintaining the flow of the original story. Deep rewriting is not the same as simple synonymisation for three reasons.

  1. Logic and Coherence - AI does not reduce the connection between cause and effect, it preserves the logical relationship between disparate thoughts and creates arguments in new ways to the full extent as appropriate.
  2. Syntax - The machine has the ability to rearrange words within any given sentence and convert from complex syntactical arrangements down to simple syntax based on the required level of complexity.
  3. No Changes Yet Unique - The output produced after the processing of the content, having passed plagiarism checks (using sites such as Text.ru and Advego), will generally have an 85-90% score. This indicates all source material, and each piece of factual data provided in those previous documents was preserved.

The finished or processed material looks exactly like it was written by a person; however, it is a different appearance of text as if the author is wearing a different outfit from what other authors would wear when creating the document. Essentially it is a function of AI, but it also serves as a co-existing partner to the original writer.

ASCN.AI — A Platform for Content Automation via AI Agents

My favorite resource for content automation via Artificial Intelligence (AI) is ASCN.AI. ASCN.AI uses a powerful neural network to paraphrase based on a multi-agent architecture (each agent has its own focus; e.g., tone of the original text is analyzed by one of the agents, and then the paraphrased output that is produced by the final agent will be checked for factual accuracy). This platform will allow you to build an AI agent for specific tasks in a No-code environment, meaning that the end-user can create an agent without having to program it. After selecting a template for article rewriting or email adaptation, simply submit the new content, and you're done.

“Multi-agent architecture allows tasks to be divided: one agent analyzes, the second rewrites, and the third checks the facts — this eliminates hallucinations.”

How to Rephrase Text with AI: Step-by-Step

I generally apply the following workflow when attempting to keep my click count down.

Step 1: Select a Platform (ASCN.AI, Quillbot, Jasper, or one from above) and Create an Account. Most platforms have free trial versions or some basic accounts. If you’re going for scale, you will want to incorporate and build a content factory through AI. Copy the original text, paste it into the box below, and then you can highlight it in Google Docs and put an extension to it (Wordtune, QuillBot, etc.). Very simple and easy!

Step 3. Configure the parameters: style (business or conversational), change type (light or deep), and target audience. In ASCN.AI, you will also be able to designate whether to keep the key terms or to optimize them for SEO purposes.

Step 4. Press generate. The text will be processed by the AI within five seconds to thirty seconds. A new version of your document will be ready either for you to copy out straight away or alter in the interface.

Step 5. Check your work. You should now identify any discrepancies between the meaning of your passage and its original. Compare both passages to check for differences in uniqueness (or if it is relevant), and simply read the new version over again. AI can create incorrect facts or "hallucinations," therefore it is important to conduct a final human check of the rewritten content.

Practice: Implementation Cases

“An e-commerce project involved automating rewriting over 4,500 product descriptions using ASCN.AI. The original product descriptions were delivered in template format. The AI reconstructed each template by taking into consideration specific, relevant keywords and creating a completely new (and unique) layout from scratch. Uniqueness went from 40 percent to 92 percent and web site traffic increased by 34 percent after three months. In the absence of automation; this level of throughput would require six months of dedicated copywriting time.”

Another example is the flash crash profit case study, where the speed of processing news via AI agents allowed for decisions to be made faster than the market. Every second counts here.

Limitations and Risks of AI Paraphrasing

When a neural network generates text, it may generate new text that replaces numbers/dates with unrelated numeric/date values in place of, for example, “the company was founded in 2022” being changed to “operating since 2021.” These errors are referred to as “hallucinations.” You must double-check the accuracy of statistics, links, and legal information. In areas such as finance or medicine, unverified material generated by an AI could result in loss of reputation or fines. Accounting automation would provide an example where it is safe to implement AI, but maintaining control over information is still very important.

Recommendation for After the Rewrites: After you have rewritten text, verify that you have all original sources reconciled back to the new material. If the rewritten material has numbers/quotations, you should use the AI only for style, not for any of the original facts.

Ethical Issues of AI Generated Content and Plagiarizing

The AI produced text is yours legally. However, is it also ethical? The answer to that question is a complex one. When a neural network rewrites material, it rewrites the material’s form — however, the concept/structure could remain that of another author. If you were to take an article from a competitor and rewrite it through the AI and present it as yours — that is intellectual theft. This is considered to be plagiarism if done in academia, and an entity could receive a lawsuit if this was done within a business. Additionally, as of 2023, search engines (Google, Bing) are penalizing websites that contain low-quality content (i.e. Helpful Content Update). Websites containing not enough expertise have low rankings through search engines.

Recommendation for Using AI as an Accelerator: When using an AI application to assist you with content generation, you should include your own examples, expertise, and viewpoint in addition to the AI generated material.

“In two years, a client of ours rewrote a competitor's entire blog using a neural network, and three months later, Google put a filter on the domain and traffic disappeared completely. It took six months for them to recover their traffic levels. Think of AI as a facilitator, not a substitute for thought.”

Frequently Asked Questions (FAQs) About Rewriting with AI

Did I need to fact-check my paraphrase and verify if I had the copyright for it?

Yes and No. (1) You're technically the business owner of that text — unless otherwise stated in the service contract. However, for you to conduct business, you must conduct fact checks and verify copyright. Paraphrasing another author’s article but not changing the essence, then posting as part of your Brand is called Plagiarism and there is always an associated Risk. In business, use artificial intelligence as a tool for speed; however, supplementing the material with your own data/cases/expert opinion will add value.

Which neural network performs best at paraphrasing Russian text?

GPT-4 and multilingual models consistently returned the best results. ASCN.AI (Multi-agent architecture preserves context), Jasper AI (GPT-4 with grammatically altered text) and QuillBot (Standard and Fluency versions). In regards to paraphrasing technical documents using an agent configuration specific to your industry terminology — ASCN.AI will meet your needs. For shorter passages (500 words or less), Wordtune or Copy.ai provides ease of use. If paraphrasing while maintaining the SEO structure requires Jasper AI + Surfer SEO. AI Crypto Analyst may assist traders/analysts.

Does Paraphrasing with AI result in the loss of an article’s SEO optimization?

It will depend on the settings you have chosen. If you select a “Deep Rewrite” (Creative mode in QuillBot), the algorithm will remove keywords or alter the header structure resulting in the loss of relevance. In order to maintain your SEO, you will need to select a “Light Rewrite” (Standard mode in QuillBot) or use platforms with SEO analysis offered (Jasper + Surfer or ASCN.AI with keyword retention). Once your document has been paraphrased confirm that the intended keywords, LSI words, and Meta Tags are intact. If the generated text you are referring to contains a synonym of your keyword, simply replace it with the original manually. Search Engines rank for how closely a user's inquiry match your keyword. For a holistic approach consider using AI Agents to market!
