GPT-3 AI writing Tool: Rytr vs Jarvis

Recently, GPT-3 became available as an API, followed by many automated GPT-3 AI writing tools that claim to create quality content. Global content-creators want to know more about these two products – do they really offer content-smart copywriting? And how does GPT-3 work for making their jobs easier?

What is an AI Writing Assistant?

An AI Writing Assistant is a machine learning-powered software that automates content generation. It uses an algorithm (or language model like GPT-3) to learn about topics of interest and can use data from other sources for inspiration.

Though the software does not come with an understanding of syntax or grammar, it learns these skills through examples input by the user. It can also be taught to detect repeating patterns in order to write more varied content. The more the program is exposed to various formats of text, the better its writing will become.

Why do Rytr and Jarvis use GPT-3?

The vast majority of these ai writing assistant tools use GPT-3 as a language model due to its availability through the API provided by OpenAI and the large number of use cases that can be generalized through fine-tuning and model parameters.

The fine-tuning process can not only significantly improve the accuracy of text generation by using examples or “few-shots”, but will also have an impact on the costs that these tools will have to bear.


If you’re looking for an affordable but worthwhile AI assistant, Rytr AI is the perfect choice for anyone who needs to publish high-quality content quickly and on low budgets, with a writing assistant that guarantees unparalleled creativity and productivity when using it. It can also create sophisticated and SEO-friendly copy for any topic.

Rytr main features

Here is a list from their own website but I will highlight the ones I find most interesting:

  • Easy to Use:  Rytr’s user interface design resembles the classic Office Word editor, allowing you to work in a familiar place.
    • Expand: Expand helps you to insert some words along the text to make it a little clearer.
    • Shorten: Shorten helps you reduce the length of the text while keeping more or less the same meaning.
    • Append: The append option simply adds a few words to the end of the selected text, useful for incomplete/broken paragraphs or sentences.
    • Paragraph: This operation is best used for writing blogs or article sections, as it allows you to generate a paragraph on the selected topic. If the topic is formatted as a heading (H1, H2, H3, etc.), the AI will generate a long introduction-type paragraph, while in cases of normal body text, it will produce a couple of sentences.
  • Autocorrect: Rytr automatically corrects any misspelled word, can be easily undone by pressing CTR+Z
  • Grammar Check: The Rytr editor acknowledges any grammatical errors in its content.
  • Sentence formatting: The Rytr AI editor ensures that the content is formatted correctly and without repetitive phrases.
  • Sentence Rephraser: Rytr is amazing at rephrasing paragraphs, just select the sentence and click Rephrase to see the magic.
  • Multiple Languages & Tones: Rytr has more than 30 languages to choose from and the Tone option allows you to choose the best tone to write in, which helps you engage your audience more effectively.
  • Multiple Output Variants: You can choose from three variants at the same time, which helps to save time.
  • Plagiarism checker: It performs a basic search (powered by Copyscape) to check if the generated text may have a plagiarism problem.

Given my occasional use of this type of tool for idea generation, text expansion, rephrasing and plagiarism checking, I have opted for Rytr because of its pricing structure.

I’ve been using Jarvis and for creating long content but using “expand” existing or generated content but you need to take care of the connectors because no GPT3 or GPT-x / LLM keeps the context. And of course they are useless with factual facts. I chose Rytr because it allows me to do fine-tuning for my use cases and the cost is a fraction of Jarvis. The main use is to generate ideas and eliminate the “blank page” block.

Think about the time it takes you to type (just move your fingers) an outline once you have it in your head and compare it to the time it takes you to review/correct some of the proposals it offers you. It saves a lot of time in that initial phase and for things like rephrasing or doing a basic plagiarism check.
