But what tool is best for you and the content you need to create?

What is AI copywriting?

AI copywriting combines natural language processing with machine learning to generate copy for social media, blogs, websites, landing pages, scripts, and more.

Though AI generates the copy, the intention is for it to sound like a human wrote it. Furthermore, AI-generated copy is crafted quickly, helping marketers meet deadlines and allot more time toward other responsibilities.

Blog Introductions

My three contenders for the best AI tool for blog writing are HubSpot's AI content writer, ChatGPT, and Scalenut. To compare each device, I typed the following prompt into each system and evaluated the introductions in the results:

“Generate a blog post listing 10 strategies for influencer marketing.”

1. HubSpot's AI content writer

Our free AI content writer can generate copy for blogs, websites, social media posts, and more. All users need to do is type in a topic or prompt and let the AI content writer do the rest.

Using the tool is simple. Just log into the HubSpot CRM and click the “Generate blog post” button near the top right corner.

Next, type in the prompt, choose the correct country, and select the blog to host your post. Then click “Next.”

From there, the AI generates several headlines to choose from. Even better, it shows how difficult it to to rank for the headline and keyword.

Below is an excerpt of what the tool generated after I selected the headline I wanted.

Get started with HubSpot's AI Content Assistant

What We Like: Overall, the tool is user-friendly, quick, and helpful. My only critique is that I'd more likely use the opening sentences as metadata and rework the first three paragraphs after the subheading to craft an introduction.

2. ChatGPT

This isn't my first time using ChatGPT to write blog content. While it's not my go-to choice, it’s an excellent tool for outlining a blog post or starting a draft.

After I submitted the prompt, ChatGPT generated a headline similar to the one I chose in the HubSpot example, and it developed an intro paragraph closer to how I'd write it myself.

ChatGPTs draft reads "Title: 10 Effective Strategies for Influencer Marketing Success  In today's digital age, influencer marketing has emerged as a powerful tool for businesses to connect with their target audience and boost brand visibility. By partnering with influencers who have a dedicated following, brands can tap into an engaged and receptive audience. To make the most of influencer marketing, here are ten strategies to consider:"; AI copywriting tools

I would have liked ChatGPT to generate multiple headline suggestions, but I would need to enter a different prompt for that to happen.

Additionally, while the opening paragraph was straightforward and to the point, it lacked detail or an exciting hook.

Pro-Tip: When using ChatGPT, be as specific as you can in your prompt or be ready to submit multiple prompts until you get the kind of content you're looking for. 

3. Scalenut

Scalenut helps users brainstorm, write, edit, and publish SEO-optimized content. Unlike other generators, I must submit the keywords for the AI's Article Writer before entering the prompt.

Once the keywords, prompt, and tone are specified, Scalenut generates several headlines to choose from. I decided on the first headline, “Ten Winning Strategies for Influencer Marketing.”

Scalenut generated the following outline with optimized subheadings.

From there, I clicked “Generate Writing Points” and was shown the points Scalenut planned to include in its draft. I could delete the points I wanted to exclude and write in new topics.

Finally, I clicked “Generate Content,” Scalenut responded with the following blog draft, which included a meta title, description, and permalink.

Scalenut's draft reads "10 Winning Strategies for Influencer Marketing: Are you looking for ways to take your brand's marketing game to the next level? Look no further than Influencer Marketing! In recent years, it has emerged as one of the most effective methods of online marketing. But what exactly is Influencer Marketing and why is it so effective? We'll explore all of this and more in this blog post. From identifying your target audience to choosing the right type of influencer, we'll cover every aspect of creating a successful influencer marketing strategy. Additionally, we'll share some tips on how to track success and build long-term relationships with influencers. So, whether you're just starting or already an expert in the field, read on to discover 10 winning strategies for Influencer Marketing that will help you increase your brand's visibility and drive sales!"; AI Copywriting tools

Scalenut's approach to AI copywriting is a very collaborative process, which is excellent for a writer like myself. I see AI as an assistive tool rather than something that can completely take over the task of writing.

There are some tweaks I would make to the final draft. For example, “influencer marketing” should be lowercase since it's not a proper noun. However, Scalenut provided a strong foundation for AI copy, and I see a tool like this saving time for writers.

So, which of the above tools writes the best marketing copy for blog posts? It‘s a tie between HubSpot’s AI Content Writer and Scalenut. Both tools include features that optimize your content SEO, which is key to crafting blog posts to rank in SERPs and generate leads.

Social Media Copy

Let's compare AI tools from SocialBee and Anyword to see which is best for developing social media copy.

1. SocialBee

SocialBee is both a social media scheduling tool and an AI post generator, so once you create your social media content, you can easily schedule your creation to your platform.

In this case, SocialBee is connected to one of my Instagram accounts.

SocialBee; AI copywriting tools

After choosing to use SocialBee's social media copilot, I answered a few questions regarding the name of my business, who I was generating content for, my role, target audience, branding, and more.

In this example, I am a social media manager for a bakery in Philadelphia that serves freshly baked goods to locals wanting a cozy, family-friendly atmosphere.

From there, SocialBee suggests the platforms I should use in my campaign, the kind of content I should post, and when.

Finally, I click “Generate Post,” SocialBee provides several social media copy drafts and the option to post them according to its suggested plan.

One post reads:

“Remember when we used to make these delicious apple turnovers? They were always a crowd favorite! #ThrowbackThursday #PhillyBakeryHistory.”

In the notes tab, SocialBee points out the types of images I should use to complement the copy.

What We Like: Planning, drafting, and scheduling a social media campaign can take hours, sometimes days, but with SocialBee, I got everything done in just 10 minutes. I also love that it provides a variety of copy for different social posts.

2. Anyword

Anyword is a free AI copy generator that is pretty simple. All I needed to do was select the social media platform I wanted to post to and then explain the post in just a few words.

For this test, I‘m sticking to the Philly Bakery example and asking Anyword to generate copy for an Instagram post enticing customers to visit my fictitious Philadelphia-based bakery. Here’s the result.

Copy reads "Indulge in the sweetest treats in town at Philly Bakery! Come and get 'em while they're hot"; AI Copywriting tools

As you can see, Anyword is a lot less comprehensive than SocialBee and doesn't provide as many suggestions.

However, it provides engagement predictions, a scale for tone of voice, and a graph predicting the demographic the caption would appeal to the most.

Best For: I can see myself using a tool like Anyword when I'm at a loss for what to post, and I need a quick copy as soon as possible.

With that in mind, I will crown SocialBee as the best AI tool for generating marketing copy for social media. SocialBee streamlines the entire campaign ideation process, from planning to drafting to scheduling, in just minutes.

Email Copy

We‘re comparing Copy.AI and Hypotenuse.AI to see which generates the best email marketing copy. My prompt is: "Generate a marketing email to customers excited about my business’ Fall clothing sale."

1. Copy.AI

Copy.AI works similarly to ChatGPT, which makes sense, considering it‘s built on top of OpenAI’s GPT-3's large language model. While ChatGPT is a general service that answers various queries, Copy.AI is designed to streamline the copywriting process.

So, how does it fare with emails? Let‘s look at an excerpt of Copy.AI’s response to my prompt.

Copy.AI's draft reads, "Dear [Customer's Name],  As the crisp autumn air descends upon us, it's time to bid farewell to the lightweight apparel of summer and embrace the cozy and stylish outfits that Fall has to offer. And we have exciting news for you – our Fall clothing sale is here, promising unbeatable savings on the latest trends!  At [Your Business Name], we understand that fashion is not just about what you wear, but also how it makes you feel. That's why we have curated a collection that combines comfort, sophistication, and affordability – ensuring that you look and feel your best while staying on budget.  Here are just a few reasons why you simply cannot miss this Fall clothing sale:" AI Copywriting tools

What We Like: The email subject is catchy and clever while creating a sense of urgency. The opening sentence captures the essence of Fall attire with phrases like “crisp autumn air” and “cozy.”

However, the entire email is about 430 words; it's best practice for marketing emails to be between 50 and 125.

2. Hypotenuse AI

Hypotenuse.AI provides various templates for different types of content, including emails. The copywriting tool also allows users to describe the purpose of the email, keywords to optimize for, tone, and more.

This is what Hypotenuse.AI came up with.

Draft reads "Subject: Get ready for autumn in style Fall is here and the weather is starting to cool off. What better way to prepare for the season than to take advantage of our Fall clothing sale? Now is the time to grab those sweaters, jackets and other stylish pieces you've been coveting.   At our company, we strive to bring you the latest looks to keep you looking your best all year round. And we've made sure that our Fall sale offers deals you won't be able to pass up.   If you're ready to make the most out of the season, browse our selection of autumn-inspired clothes. Shop now before this sale ends and you miss out on these amazing deals!" ; AI Copywriting tools

What We Like: I'm much happier with the length of the email, which is less than 120 words. I also love the call-to-action at the end for being short and to the point and encouraging readers to act now.

After all, a little FOMO never hurt anyone.

The email doesn't have as many fluff words as the draft from Copy.AI, but overall the draft provides a great base to build upon and tweak to my liking.

Between Copy.AI and Hypotenuse.AI, I would choose the latter to craft my marketing emails. Hypotenuse.AI provides more email customization options and opportunities to optimize for SEO and target audiences.
