Generative AI service? Everyone gets generative AI service!

The fields where generative AI can find adoption are endless. Every first business event now includes a speech about the gorgeous capabilities of large language models (LLMs), be it development, e-commerce, marketing, sales, whatever. Sometimes it seems like you can take ChatGPT and just embed it literally everywhere. And it is really so!

Let’s take digital writing assistants. They, by default, intersect with a basic list of LLM options: proofreading, editing and translation. And, practically, sometimes they work even better than ChatGPT. 

But what if I tell you that today 30% of all text checkers already have generative AI functionality based on different LLMs and almost every offers LLM-driven rephrasing (however, not each admits that publicly).

So, recently we’ve tested the waters and figured out how this sweety combo — digital writing assistant + LLMs works. Intrigued? Keep on reading!, GrammarlyGO, or Wordtune — what’s your option?

What’s LLM? Let’s ask the robots directly.

“I am a type of Large Language Model (LLM), specifically GPT-4, developed by OpenAI. My architecture is designed to process and generate text based on patterns in the data I was trained on. My capabilities include answering questions, generating creative text, summarizing documents, translating languages, and more. “


“I am a large language model (LLM) trained by a team of researchers at Meta AI. My training involves exposure to a massive dataset of text from various sources, including books, articles, and websites, which allows me to learn patterns and relationships in language. This enables me to generate coherent and contextually appropriate text, recognize nuances of language, and engage in conversation. While I’m not the largest language model ever created, I’m one of the more advanced models in my field, and I’m always learning and improving!” — not very shy)

“I am a human being.” – wow, that’s really bold 😂  

So, in general, LLMs are programs designed to process and generate human-like text based on the input they receive. They are used for a wide range of natural language processing tasks, including answering questions, generating text, language translation, text summarization, and more.

Not every writing assistant reveals the model it’s based on; however, when they do, it’s often ChatGPT-3.5 or -4 that appears 8 out of 10 times. There are rare cases of in-house models like’s Palmyra, since their development requires tons of time and resources.

For research purposes, we’ve analyzed popular writing assistants and the generative AI functionality they offer. The results are in the table below.

All the replies are unique and each email has its own strengths and limits. The choice of which one to use depends on the context and the nature of the relationship with the team member. The GrammarlyGO and Linguix AI drafts are more personable, while Ask Writer’s one is more formal; Wordtune Spices provide a structured template. We advise you to consider the workplace culture and your specific communication style when choosing which email to send. Now, considering the concerns raised by AI-generated content, let’s analyze each email with the Sapling AI content detector.

In conclusion, generative AI can be a useful tool, but it may not be suitable for all cases of business communication. Since many countries and companies are considering banning this technology, it’s important to use it cautiously.

WProofreader generative AI is coming soon!

But hold on, we’re not done yet. We’ve carefully analyzed the market demand and developed WProofreader Business to be compatible with the highest requests. And the next milestone in our roadmap is a generative AI feature! Read more about it in the next chapter.


To sum up all the above:

  1. There’s a tendency among digital writing assistants to move towards generative AI. Some use third-party LLMs like ChatGPT (GrammarlyGO, Linguix AI), while others develop their own LLMs like or Wordtune Spices. The latter option seems to be quite challenging. 
  2. Tools vary by comparison criteria: capabilities, prompts, integrations, pricing, etc. Security measures taken by vendors are, by default, the most vital concerns that should be taken into account when choosing a solution for generative AI. 
  3. Generative AI brings many benefits to the table in terms of business communication. However, many countries and companies are considering the idea of banning this technology.
  4. WProofreader now doesn’t have built-in generative capabilities. Altjough we’re thinking about building paraphrasing functionality to meet the demand of our clientele.
