Best AI Writing Generators – Blog post image

Since ChatGPT launched in 2022, the market has been flooded with AI writing generators.

So, how do you pick the right one for your business?

They might all seem similar on the surface. But each option comes with unique features for different uses.

We’ve tested more than 20 AI writer tools and narrowed our recommendations down to five of the best.

This article breaks down each tool’s best-suited use cases, features, pros and cons, and pricing.

Let’s begin.

Our Criteria for Best AI Writing Generator

When selecting an AI writing tool, it helps to be intentional with your criteria. We used the following when doing our testing:

  • Output quality: Is the text produced clear and grammatically correct? Does the AI-generated content still sound natural, like it came from a human writer?
  • Content types: Can the tool handle writing for a variety of content types? Does it do an especially good job with any particular ones?
  • Customization and control: How much control does the tool give you over its output? Does the tool save brand voice and writing style to use automatically with future prompts?

Which Is the Best AI Writing Generator?

Here’s a quick overview of the five top AI writing generators reviewed in this article:

AI Writing Generator Best for Price
Jasper Social media content, ads $49/month; 7-day free trial

Jasper – Homepage

Jasper is an AI writing generator made especially for creating marketing copy.

It comes with over 50 templates, which makes it a great tool for creating nearly any type of content. Some of its most useful templates include video script outlines, blog content outlines, social media captions, and ad copy.

The variety of templates makes it an especially great choice for social media and running ads.

Create Complete Marketing Campaigns From a Brief

With Jasper’s Campaigns feature, you can create complete marketing campaigns from a single brief. Jasper can even create the brief based on your campaign summary.

There’s no limit to how many assets you can select.

Get Jasper to Use Your Brand Voice

Teach Jasper about your company, and the Brand Voice feature will use AI to generate text in a style that aligns with it.

Jasper can also learn your style and tone by analyzing your existing content. Then you can adjust it as needed. Like this:

Jasper – Brand voice

Jasper saves your tone of voice and generates content that sounds like you on future assignments without prompting.

Chat with Jasper to Generate Ideas

Use Jasper’s Chat feature to interact with the tool in a conversational way. Ask AI to generate content ideas, write your social media posts, revise your content, and more.

2. Copy.ai

Best AI writing generator for automatically creating content with Workflows.

Copy.ai – Homepage

Like Jasper, Copy.ai is an AI writing generator that’s helpful for creating blogs and social media posts. It requires very little input to generate unique content.

Copy.ai is especially useful for creating content at scale using automation with Workflows.

Automate Output With Workflow Templates

There are two primary ways to interact with Copy.ai: Chat and Workflows. The Workflows option is particularly helpful for working on large-scale content creation in an automated and repeatable way.

Copy.ai – Workflow template

You can use existing Workflow Templates to kick off content generation.

For example, the “Extract from LinkedIn Profile” template will synthesize information from a person’s LinkedIn page. Or, the “Newsletter from Recent News” template will gather information from an identified news source and create an engaging email newsletter based on what it learns.

You also have the option of creating your own custom Workflows with actions like “Extract Educational Details,” “Summarize Recent Posts,” and “Recommend Copy AI Use Cases.”

Workflows help you create content at volume. Especially if you’re making use of the more advanced API integration, using the integrated tools, and embedding Workflows as forms.

Use Chat to Brainstorm and Refine Ideas

Use Copy.ai’s Chat feature to provide prompts in a conversational way and get written text as output. For example, you can ask Copy.ai to:

  • Generate a personalized email
  • Summarize a large piece of content (including from a link or PDF file)
  • Write a blog post about any topic
  • Create a social media caption

After you add your brand voice in Copy.ai, the tool’s outputs will be generated in that voice.

3. ChatGPT

Best AI writing generator for blog and article outlines.

ChatGPT – Homepage

ChatGPT is an AI chatbot that was released by OpenAI in November 2022. It’s trained on a huge dataset and responds to user prompts with content in a wide range of requestable forms.

We’ve found it to be especially adept at creating outlines for assets like articles and blogs.

Add Custom Instructions for a More Precise Output

Custom Instructions lets you add information to ChatGPT so that it always returns responses that are relevant to you.

To find this feature, click your profile at the bottom-left corner of the screen and select “Customize ChatGPT.”

ChatGPT – Customize ChatGPT

For example, let’s say you run a blog about smart home gadgets. You could provide the following Custom Instructions to let ChatGPT know about your project and your goals.

  • “I run a smart home hardware blog that helps readers discover the best gadgets and get the most out of their smart home setup.”
  • “Respond in a casual tone. Imagine you’re talking to a friend. Don’t use jargon.”
ChatGPT – Customization

ChatGPT will memorize your instructions. And the next time you want it to generate text, these instructions will be referenced without you having to enter the information again.

For instance, if you ask ChatGPT for five blog post ideas, you won’t need to explain what kind of blog you have again. It will generate ideas relevant to the blog information you previously provided.

ChatGPT – Blog post ideas

Configure Memory Access to Save Time

ChatGPT has memory across chat sessions. It memorizes your prompts and follow-up interactions and uses them to provide more relevant responses in the future.

So, every time you chat with it, ChatGPT learns more about you, your project, and the way you want it to respond.

Pros and Cons
