Best AI Writing Assistants [2021]

Artificial intelligence copywriting is doing more and more for businesses as these tools improve. As such, AI writing assistants are a booming trend in the direct-to-consumer AI space.

All content creators feel constrained by the amount of content they can reasonably create. Don’t you wish you could write 10 articles a day instead of struggling to get through just one or two?

This is where AI writing assistants might come in.

The AI NLP market is estimated to be worth $15 billion. And is forecasted to reach over $42 billion by 2026 (CAGR of 21.5%).

And over 60 consumer-facing projects already use GPT-3 technology. 

Also, it’s important to note that an AI copywriter isn’t going to be able to do everything for you perfectly. AI writing is simply a tool to help make copywriters more productive.

Here are a few examples of trending AI-powered copywriting tools:

Limitations to AI copywriting tools

Remember that these tools are just machines. You only get out of them what you put in.

Essentially they take human-created content and mix it up to produce something new.

In other words, these tools are still not anywhere near what a human can do.

AI copywriting might be okay when it comes to bulk projects, if you need something truly original and something that’ll set a personal touch, it might not be a good solution for a long time.

You’ll also need to proofread what AI copywriting assistants spit out to make sure it’s grammatically accurate and otherwise makes sense.

They’re a tool, but certainly not a substitute to human content creation.


AI copywriting assistants are an exciting technology for a digital marketer or a busy copywriter.

AI copywriting tools can help you scale your content creation and achieve your business goals in ways that otherwise wouldn’t be possible.

You would need to hire a large team that you couldn’t afford, and increasing your productivity can only go so far.

These tools are easy to learn and fun to use and are increasingly producing natural copy.

But every AI copywriting tool is slightly different.

And at the same time, you might believe that AI writing software isn’t there yet technologically and choose to wait until they’re sophisticated enough to be worth the investment.

Accordingly, it’s best to check out a free trial or two before you commit to a purchase.

This way, you’ll get a sense of how the tools work and if they’re right for your needs and overall business strategy.
