The Best AI Copywriting Tools for 2023


AI copywriting is the creation of written content via machine learning and natural language processing (NLP) software. 

You can write anything from ad copy to blog posts with the help of AI copywriting.

AI copywriting software works by scraping the web (or analyzing a similar input) for related content, learning about it, and providing new copy based on these findings.

Below, we’ll cover how AI copywriting works, its limitations, and nine of our favorite tools to get you started.

AI copywriting tools use NLP and machine learning software to understand how humans learn—and write.

These copywriting bots can only provide content based on what already exists online. 

But they sift through this information far faster than humans can. AI copywriters scrape and analyze millions of webpages in seconds. 

But keep in mind that there are limitations (which we’ll cover later). Because these bots reference existing content on the web, there’s no guarantee that the generated copy will be 100% accurate. You’ll need to review the results yourself.

However, using AI copywriting tools is a great start if you have writer’s block. Or want to generate new content ideas quickly.

Here’s an overview of how you can produce copy via AI tools:

  1. Choose a topic you want to write about
  2. Provide your copywriting tool with guidelines (like your content goals or desired tone of voice)
  3. Wait for the tool to generate your AI copy
  4. Review results for accuracy and desired tone

Here’s what it looks like in action:

producing a copy via AI tools

And here’s a real-life example:

Say you’re writing a blog post and want an eye-catching headline. Give the AI copywriter your topic—or an example headline—to generate new ideas.

It’s like giving freelancers or in-house writers a content brief to guide their efforts. The more information the writer has, the better the copy will be.

As a result, AI copywriting tools are excellent partners for content writers (rather than replacements). These tools can help writers create content more quickly.

AI copywriting software can save you lots of time. 

There’s no need to spend hours brainstorming the perfect content topic or headline. Tell the AI software what you want to write about, and it’ll generate content ideas in seconds.

You can even streamline more tedious writing tasks, like creating product descriptions for your ecommerce site.

Here are some more examples of what you can craft with the help of AI copywriting tools:

  • Blog post ideas and outlines
  • Title tags and meta descriptions
  • Ad copy
  • Social media posts
  • Call-to-action (CTA) copy

By using an AI copywriter to handle time-consuming tasks, you’ll have more time to focus on larger projects that will have a bigger impact on your business.

Think of AI-generated content as a first draft. It’s important to fact-check, to match the copy to your brand voice, and to check for plagiarism. Because of this, we recommend assigning tasks that involve AI content to an experienced human writer.

How to Overcome AI Limitations

AI copywriting can be incredibly useful. But it has its limits.

Treat it like any other digital marketing tool—as a starting point. 

Think about it this way: 

Using an SEO tool doesn’t automatically make you an SEO expert. But it will make your life a lot easier.

The biggest limitation of AI copy? 

AI copywriting tools analyze existing content written by human writers. Then take this information to produce something “new.”

Which means the copy isn’t truly 100% original.

That’s why it’s crucial to edit AI-generated copy and check for plagiarism before publishing.

But even Google believes there’s a place for AI-generated content on the web.

So long as the content is original, high-quality, and “demonstrates qualities of what we call E-E-A-T: expertise, experience, authoritativeness, and trustworthiness.”

Google’s advice is to take a people-first approach. The search engine giant provided a few examples of existing AI-generated content that don’t break any guidelines: 

  • Sports scores
  • Weather forecasts
  • Transcripts

Using AI to generate content meant to manipulate search engine rankings, however, violates Google’s spam policies.

So when you use AI copy, ensure that you’re providing valuable content to your readers. Not trying to take a shortcut to rank higher.

Tip: Learn more about E-E-A-T and how you can use these factors to create great people-first content.

Advancements in AI

AI has recently made big strides in the world of marketing and content creation.

In May 2020, a paper titled “Language Models are Few-Shot Learners” described an AI model called GPT-3 175B. The model produces human-like text thanks to NLP advancements.

This model is the foundation of many AI copywriting tools on the market today.

Fast-forward to November 2022. OpenAI launched ChatGPT—a chatbot that acts as a human conversationalist. Users can ask ChatGPT questions and receive AI-generated answers within seconds.


SEOs and content creators have already found plenty of ways to leverage ChatGPT. Here are just a few:

  • Brainstorming content ideas
  • Rephrasing copy to avoid duplicate content
  • Creating summaries of longer text
  • Generating structured data
  • Writing title tags and meta descriptions

ChatGPT uses AI technology to streamline writing tasks. Similar to spell check, AI is a tool that can help writers create content more effectively and efficiently.

But it’s worth repeating: Human supervision is crucial.

In fact, ChatGPT has caused quite a controversy in the SEO community already. 

But Google Search Liaison Danny Sullivan clarified on Twitter that AI content itself isn’t inherently bad. Instead, “content written primarily for search engines rather than humans is the issue.”

So we recommend using AI tools as a starting point. Or to automate time-consuming, repetitive tasks. But use your judgment and only publish useful content that represents your brand well.

How to Choose the Right AI Copywriting Software 

Your perfect AI copywriting tool will depend on your business needs.

Here are a few things to consider as you weigh your options:

  • SEO. Does your software measure the readability of your content? Or provide suggested secondary keywords? Your AI copywriter should be able to evaluate copy for SEO best practices.
  • Tone of voice. You don’t want your AI-generated copy to sound robotic. We recommend opting for tools that can accurately judge tone of voice and provide recommendations.
  • Ease of use. The point of AI copywriting is to save time. So it’s best to choose a user-friendly option with a simple interface.
  • Plagiarism detection. Because of AI copywriting’s limitations, you’ll want to rely on a solid plagiarism checker.
  • Integration. Check whether your tool of choice integrates with third-party apps. Many options (like Semrush’s SEO Writing Assistant) integrate with Google Docs, WordPress, and Microsoft Word.
  • Export options. Ensure you can easily export your generated text to documents, spreadsheets, etc.
