With newer AI writing assistants emerging from time to time, it may become hard to select the right one, especially in light of these glossy reviews competing for your attention.

That there are so many of them can also cause decision paralysis. But it doesn’t have to be like that. The first thing you need to know is that not all AI copywriting tools are for you.

If you are a blogger, it would be a waste of your resources to select an AI writing software created for eCommerce. And vice versa.

I created this article to show you why each AI writing assistant exists, the features that set it apart from the rest, and how you can select the one that will help you achieve your business goals.

Let’s get into it.

What is an AI writing assistant?

An AI writing assistant is a type of AI-powered software to whom you can delegate your content writing tasks. They are built on GPT-3, a machine learning model built by Open AI, and use natural language processing (NLP) to create human-like text.

An AI writing assistant can write original content that sounds exactly like human-written content. This means the content they create is original and isn’t plagiarised. They can also proofread, rewrite, and paraphrase content and sentences. SDurthermore, ome are used for SEO.

They can also generate lots of content and long content within a timeframe that’s impossible for humans. For example, some AI writing tools can create a blog post within five minutes.

What are the best AI writing assistants?

I’ve always maintained, even in all my previous posts, that best is subjective. These tools all offer some good-quality content, going by my experience using them.

However, there is a tool that helps you attain your goals. And there is the one that’s not meant for you. Contrary to the popular generalization, I’m going to explore the best options based on how versatile they are and how well they fulfill their promises to their primary target users.

The best AI writing assistants, in my experience, therefore, are as follows:

Frequently Asked Questions about AI Writing Assistants

In this section, I look at some of the most frequently asked questions about AI writing assistants.

Is there a free AI writer?

There are many free AI writers out there, although they all have paid versions. You can use the free version of Rytr and Copy AI, but they have limitations in terms of how many words you can create.

Hence, the paid option is the best.

How do AI writing assistants work?

An AI writing assistant is built on OpenAI, a platform that gives access to GPT-3. GPT-3, which stands for Generative Pre-trained Transformer, is a neural network machine model that’s been trained to use information from the Internet to generate text. 

So, once you input your idea or title into an AI copywriting software and command it to write, it goes through millions of information across the web and then creates the type of content you want for you within seconds.

Will AI assistants replace authors?

No, AI will not replace authors but collaborate with them. The implication is that authors who collaborate with AI writing software will be able to get things done faster.

What should you look for in an AI writing assistant?

Before you settle for any AI writing assistant software, here are the things you should check out:

  1. The type of content it creates
  2. Pricing
  3. Scalability
  4. Integrations
