Copy.ai
Best for Beating Writer’s Block
Copy.ai is an artificial intelligence writing tool designed to help marketers, business owners, and copywriters create various forms of content, including website copy, sales landing pages, email, and social media and blog posts. A boon to content marketers, Copy.ai can automatically conduct SEO research and produce content briefs for writers, streamlining the production process and giving writers guidance.
Another distinctive feature is the thought leadership tool, which automatically turns raw transcripts from interviews with experts into a variety of content assets, including blog posts, social media posts, and newsletters. This dramatically reduces the time it takes to manage content repurposing. The AI writing tool also lets you easily generate copy that aligns with your organization’s persona.
Copy.ai’s in-platform AI chatbot acts as a writing assistant to help beat writer’s block by aiding with brainstorming. For example, I asked it to give me 10 Instagram post ideas for fashion week—it delivered 10 useable ideas I could use as the basis for my social posts. These features enable your team to create and distribute more high-quality content at a lower cost than before.

Copy.ai’s templates page gives a range of options for different content types.

Rytr
Best for Copywriters
Rytr is an AI-powered writing tool capable of producing copywriting content on various topics. It’s one of the best AI writing tools for commercial copywriting jobs, where copywriters can use it to automate the creation of post and caption ideas, paragraph content, SEO meta titles, emails, call to actions, replies, and other less complex copywriting assets.
The platform also supports more than 40 other use cases, including generating blog ideas and creating job descriptions. In addition, paid users can create their own use cases by training Rytr for their specific needs.
I tested Rytr out for copywriting and asked it to write me a call-to-action for “A knee pad that protects middle-aged gardeners from hurting themselves.” In response to my prompt, it provided the following two variants:

“Safeguard your knees, garden with ease.”
“Safeguard your knees, garden in comfort.”

When I changed the tone from “convincing” to “humorous,” it generated two more options that were not useable out-of-the-box but were still useful for ideation:

“Kneel with confidence, gardenlords!”
“Unleash your inner knee-jerk green thumb!”

Overall, Rytr its a useful AI writing tool for copywriters who want to streamline their writing process and come up with more ideas for a variety of content types.

Rytr’s copy generator environment lets you set the variables for how it acts on your prompts.
Pros and Cons

QuillBot
Best for Paraphrasing
QuillBot is an AI-powered writing assistant that, unlike most AI writing tools, focuses on helping you paraphrase and summarize texts. This makes it great for content marketers who often have to write repetitive copy with slight variations across their different content assets or even within the same blog post. For example, instead of writing “automate your administrative accounting tasks” five times, they could use QuillBot to spin that into five different variations.
It also functions as a citation generation tool, making it somewhat useful for academics—but it may not be the best tool for writing essays and research papers, as its output doesn’t consistently pass AI detection tools.
One of QuillBot’s standout features is the ability to choose from nine modes of paraphrased output. You can select from natural, academic, simple, creative, shortened, expanded, and more. As an example, when I prompted it with “The shift to agriculture took thousands of years” in academic mode, the output read, “The transition to an agrarian society spanned several millennia.”
Overall, I found the tool helpful for the outwardly simple but cognitively-taxing task of coming up with new ways to express your ideas in writing.

QuillBot’s paraphrasing environment lets you choose from nine styles of writing you’d like it use.
Pros and Cons

Pros

Frase.io
Best for SEO Teams and Content Managers
Frase.io is an AI writing tool designed to help you generate content, provide suggestions for better writing, and optimize articles for SEO. SEO teams and content managers use its templates and outline builder to automatically produce article structures that align with the intent of the searcher, and as a result, increase the chances that the article will rank highly in search engine results pages (SERPs).
Frase’s keyword optimization feature will identify important keywords while you write, make suggestions about how frequently to use them, and track how often they are used in the copy. In addition to keyword tips, it also tells you the ideal number of headings, words, links, and images your articles should have to outrank the competition.
Many of the SEO managers I’ve worked with have used Frase, and I’ve found it especially helpful for optimizing articles for SEO. Watching the SEO “topic score” go up as I make edits is motivating and lets me know I’m on the right track.

The Frase user interface provides detailed information keyword use while you write.

Anyword
Best for Copywriting Performance Analysis
Anyword is an AI writing tool that uses machine learning algorithms to generate content and analyze the performance of your copy across various channels. What distinguishes the tool is its Copy Intelligence functionality, which analyzes all of your previously published content to determine which messaging works best on your website, ads, socials, and email channels while clueing you into opportunities to improve your copy.
Its Target Audience feature lets copywriters and marketers define their ideal readers down to their key problems and desires. The AI writing tool will then take this into account when creating and analyzing content.
I found Anyword’s templates extremely helpful for prompting the AI writer to create content that fit my needs. In addition, its self-guided wizards walked me through the information I needed to provide the tool for it to write a blog post or ad campaign for my needs.

Anyword’s templates view lets you choose the type of content you want it to create.

It can be used in a wide range of contexts, including writing emails, reports, essays, or social media posts.
Grammarly can be used as a browser extension, a desktop application, or a mobile app. It’s free to use with limited features, or is available with additional functionalities as a premium subscription.
I’ve found Grammarly’s free version to be extremely useful as an AI editing tool. When I use it to run a final grammar and spelling check on a finished article, it inevitably catches mistakes and offers solutions to fix them. I also use it when writing emails to get the tone right. For example, when emailing a new client, I like to make sure the tone is confident and upbeat—Grammarly’s tone detector helps me achieve that goal.

Grammarly grammar checker is easy to use and effective for a wide range of applications.
Pros and Cons

Pros
Cons

Some suggestions misalign with your desired voice or style

Free version is sufficient for most writers and editors
Free plan doesn’t have advanced clarity features

Pricing

Hemingway Editor
Best for Content Readability Measurement
Named after a writer known for his concise and simple prose, Hemingway Editor is a writing tool that helps you enhance the clarity, grammar, and readability of your written work. It analyzes text and provides various readability suggestions while highlighting lengthy, complex sentences, excessive adverbs, passive voice, and hard-to-read phrases.
It also assigns a readability score based on the grade level required to understand the text. If the score is too high, content writers can tweak the highlighted sentences to lower the grade level. It is available both as a web-based application and as a desktop app.
I’ve used Hemingway in various capacities and I find that it does its main job of measuring content readability extremely well. Its passive voice detector is my favorite part of the tool.
That said, one of the risks of using an AI editing tool like Hemingway is that, if you follow its suggestions without thinking, you may edit all the rhythm, flow, and personality out of your writing, leaving you with text that’s plain, lifeless, and stilted and suited for a grade level well below your target. Overall, though, I’ve found it a useful tool for making sure blog content is clear and easy to understand while streamlining the editing process.

Hemingway’s Editor interface offers a wide range of improvements to suit your target audience.
Pros and Cons

Pros
Cons

Helpful color coded suggestions
May not align with your writing style

Simplifies editing process
Can lead to overly simplistic prose

Pricing
The platform is free to use.
Key Features

Improves writing clarity and conciseness

Writesonic
Best for Blog Content Writing
Writesonic uses artificial intelligence technology, specifically natural language processing (NLP), to provide content generation services. It’s one of the best AI writing tools for creating full blog posts.
Writesonic’s AI can generate text based on prompts and user input. In the case of creating a blog post, the wizard will ask you to input information such as article length, keywords, number of headings, topic, and references. Once you’ve approved of the outline, it’ll generate a blog post following these instructions as well as SEO optimization best practices.
While it can be a helpful resource for automated content creation, the quality of generated content may vary, and human editing is often required to ensure accuracy and coherence.

Writesonic’s Library dashboard view is easy to use and provides detailed information at a glance.
Pros and Cons

Pros
Cons

AI Writer
Best for High-Output Bloggers
AI Writer is designed to generate full-length articles in minutes, making it great for high-output bloggers, affiliate marketers, and other people who need articles fast. The platform lets you tailor the AI’s writing to your specific needs by selecting from a long list of recommended keywords for your topic or by manually inputting your chosen keywords. It also suggests sub-topics for your article and helps you structure your content with headings. The tool even cites its sources, displaying journalistic responsibility.
Significantly, it helps you choose topics about which to write. While exploring the platform, I found its topic generator helpful for coming up with article topics using a seed keyword—after prompting with “cold calling,” for example, I received a long list of article keywords and their associated traffic. I then selected Research and Write, a one-click article feature for Cold Calling Leads, and within minutes, I had a basis for a new 600-word article on the topic.
Compared to other AI writing tools, AI Writer’s blog content creation was incredibly quick. However, a note on quality—although AI Writer’s articles are typically well-written, SEO-friendly, and factually correct, they could benefit from a writer’s touch. When I took another pass to add personality, anecdotes, actionable insights, and personal experiences to the copy, it became more appealing to readers and search engines.
