Key Takeaways

  • GPT-3, or generative pre-trained transformer, is one of the most sophisticated language models at the moment and a successor to GPT-2.
  • It builds upon the same Transformers-based architecture as GPT-2 but weighs in at 175 billion parameters, which makes it the largest NLP transformer to date — bigger than GPT-2 and Microsoft Research’s Turing-NLG.
  • Since GPT-3 has been out for a while, we have several applications using the new language model for better and more efficient ways of generating code and writing content.
  • One of the promising use-cases of GPT-3 is for generating copywriting materials such as passages, product descriptions, article headlines, and ad copies, among other things.

GPT-3, or generative pre-trained transformer, is one of the most sophisticated language models right now. It is developed by OpenAI and is a successor to their previous model GPT-2. The new model utilizes deep learning — a part of the machine learning method based on artificial neural networks — to generate human-like text. What separates it from GPT-2 is that it weighs in at 175 billion parameters — compared to 1.5 billion on GPT-2. This massive increase in parameters makes GPT-3 more accurate and effective at generating texts that are (somewhat) indistinguishable from their human-written counterpart.

However, this is not the first time that OpenAI has come up with an AI-backed language model. And, their previous release, GPT-2, was a reasonable success, which found its applications across different domains — the game Dungeon AI being a good example. But, like most language models, it also had some shortcomings. Chief of these being the lack of coherency encountered after a couple of paragraphs while generating a passage, which rendered the text discernible and easily identifiable as non-human sounding. And, also the inability to generate long-tail blog posts.

What is GPT-3?

With its latest release (GPT-3), though, OpenAI has managed to address most of the shortcomings of GPT-2. As mentioned initially, the new model weighs in at 175 billion parameters, which makes it the largest NLP (Natural Language Processing) transformer to date. In fact, not just that, with this rise in parameters, GPT-3 also overtakes both GPT-2 and Microsoft Research’s Turing-NLG (Natural Language Generation) — gaining a colossal lead over the latter, which used to be the biggest language model until GPT-3 happened. As a result, GPT-3 lends support for comprehensive writing with increased effectiveness and efficiency, which, in turn, makes it hard to distinguish a GPT-3 generated writing from that of a human copywriter.

That said, while GPT-3 manages to impress on so many fronts, it is still far from passing the Turing test. [Turing test, for the uninitiated, is a test named after Alan Turing. It is carried out on Artificial Intelligence systems to determine their human-ness, i.e., to find out if they are capable of thinking like human beings.] And the reason for this is the fact that GPT-3 gets tricked when subjected to non-sensical queries. As, in such instances, rather than pointing out the absurdity of the query, the system tries to find and respond with an earnest answer.

Unlike GPT-2, which faced impediments initially but was later made available to the public, OpenAI is limiting access to its new model and only offering it to experimenters via API (application programming interface) access. Apparently, this is to prevent the misuse of the model in spreading disinformation and fake news, among other questionable use-cases. As by taking the API approach, the control now lays in the hands of the authorizing body that gets to decide who can experiment with GPT-3 and for what purpose. And, it is only after these requests are approved that the experimenters get to use the model for their application.

Now that it’s been a while since GPT-3 is out, and the organization is offering GPT-3 API access to experimenters, some have managed to capitalize on the language model and showcased some interesting use-cases. As a result, we have several applications using the new language model to implement better and more efficient ways of doing things like generating code and writing copywriting materials such as passages, product descriptions, article headlines, and ad copies, among other things that can be very useful for content marketers.

Best GPT-3 Tools for Copywriting

If you are into content marketing and have been keeping an eye on GPT-3 and are interested in trying it out for your writing needs, we have curated a list of some of the best OpenAI’s GPT3 tools for copywriting that you should help you with your different content generation needs. Just to give you an idea of how these tools work, in general, most of them utilize the data available in the public domain to extract information and generate legible text with the help of Artificial Intelligence, which is what allows them to perform these tasks quickly and effectively. Similarly, content automation using these AI copywriters takes only a few steps: you select the category of the copy you want, describe your product/service, and put the platform to work in the background to provide you with your desired output.

Here are six of the best copywriting GPT3 tools in no particular order. Make sure you read through till the end of the article to know which tool is the one for you. Also, some of these have limited-time LifeTime Deals that we have linked to.

1. Shortly AI

While most of the GPT-3 tools in this list act like swiss army knives with lots of different tools and templates, Shortly AI aims to do one thing and do it better than everyone else. Shortly AI promises to cure copywriters and bloggers of writing blocks. Be it a complicated blog post or a crime thriller novel, Shortly can help you write with just a click. The idea here is to start writing the article/novel and use the AI to complete the sentence or a paragraph. In our testing so far, we saw Shortly AI do a stunning job at this. Quite clearly, it’s by far the best AI writer for long-form content.


Shortly’s interface is like a blank canvas and can be used to write anything. The right side is where you write and the left sidebar has some basic settings/inputs to help AI understand what you are trying to write. You can even stop the AI from reading some parts of the text if you think it’s getting stuck in some patterns. This is how you have (almost) complete control over what the AI writes for you. And the best part? You can “instruct” the AI to help you out with anything using normal conversational commands. Pricing is also very simple like its interface. There is just one plan available for Shortly. You can either choose Annual ($24.99 per month) or Monthly ($39.99 per month). There’s a 3-day trial if you prefer to try before you pay.

2. Writesonic (formerly MagicFlow)

Writesonic is another GPT-3 based tool that lets you create different kinds of marketing content with just a few steps. It was initially launched as MagicFlow with limited functionalities. Back then, the service only allowed creating landing pages, product descriptions, and ads for Google and Facebook. However, its developers have since then worked on it and introduced a new avatar with an expansive scope of use-cases.


The new version, Writesonic, is essentially an AI copywriter that you can use to create blog copies (intros, listicle ideas, blog ideas), article summaries, and YouTube titles. In addition, you also get some functionalities from the previous version like generating eCommerce copies (product descriptions), headers, and digital ad copies for Facebook and Google. The platform offers three paid plans: starter, professional, and business, with different sets of features. However, those interested in checking out the service before making a payment get a free trial with access to limited functionalities. Writesonic is currently running a lifetime deal on AppSumo where you can grab a license for a one time payment of just $59.

  1. My goodness. Just tried ALL of them and they are worth the weight in gold. I’m starting with Headlime subscription but trialing others as well. Thank you so much for this

  2. I bumped on this article while researching for GPT-3 tools on Google. I can’t thank you enough for writing this. Our agency will save loads of $$$ using GPT3. Copysmith looks great and I’m starting with them now.

  3. The first time I heard anything about this new breed of AI copywriters that actually grabbed my attention was when one of the YouTube marketers I follow was very excited about one of these AI programs, in this case, Conversion AI. Then I saw that another guy I was following was head-over-heels for Writesonic.

    I thought I better look into this more, even though such a thing was hardly on my radar and quite frankly I figured it was just some new-fangled “copy-spinning” software and I’ve never really cared much for those.

    So, after briefly reviewing my options, I concluded that at $29/month, I wasn’t going to go with Conversion AI. After reading up on what my YouTube friend was discussing about WriteSonic I came across another commenter who was saying all kinds of wonderful things about Niche$$$ so I was off to AppSumo to review the two offerings.

    I was leaning towards Niche$$$ because it was truly unlimited, no credits or tokens (unlike WriteSonic which had limits, something like 40 credits per month,) I don’t like limits, lol. Besides, I don’t think I’ve ever seen a more highly-rated product ever at Appsumo.

    Niche$$$ had a solid 5-stars across the board, with lots of reviewers. So, with my cursory investigation complete I went with Niche$$$. I haven’t even tried it yet, I’m so nervous about meeting my new friend, I’m still poking around the inter-webs to see what others are saying and what the whole GPT-3 technology is all about.

    This may be a historical game-changing moment in time where we have to rethink everything. Nothing is more important, arguably, in marketing than wordsmithing. Those that get in on this early and work their tails off may come out far ahead of their horse & buggy contemporaries. The future is bright and SCARRY. The singularity, it seems, is near.
