roundup of the best ai writing tools

Brands doing sales, email marketing, social media, and blogging for SEO have an insatiable demand for content

The problem is, content takes time and manpower to create. 

The size of the content market is expected to grow to $418 billion by 2025. 

As such, numerous artificial intelligence (AI) writing software tools have emerged to support content creators.

AI writing software is sophisticated enough to take on the voice of your target demographic and generate content in half the time. 

Each of these tools has its own strengths and weaknesses. Grammarly is the most well-known, but it’s mostly for generic grammar optimizations. Whereas tools like Jasper and GrowthBar are powerful long-form content creators (with the click of a button) and can help you optimize your articles for SEO.

Are you trying to save time writing SEO-optimized blog posts or are you making huge volumes of social media posts? Do you have a team or are you a solopreneur? How price sensitive are you?

1. GrowthBar: Best for Bloggers

GrowthBar is hands down the best SEO tool for bloggers and content creators. It’s an all-in-one AI tool that enables you to create content with a button click, audit your content for SEO best practices, perform keyword research, and spy on your competitors’ strategies. 

The long-form content editor is the hero product.

GrowthBar is built atop GPT-3, the most sophisticated natural language processing model ever created. With one click, you can create a blog post outline with drag-and-drop headlines. From there, you can click a button and GrowthBar’s algorithm will read your content and generate hundreds of words at a time, filling your blog posts with awesome, unique content. 

Plus, there’s also a WordPress plugin so that you can operate directly in your CMS (if you’re a WordPress user).

GrowthBar also enables you to generate blog ideas, standalone paragraphs, and much more. 


  • AI content outlines
  • AI content creation
  • Writing editor interface that scores your work, counts keyword usage, and paragraphs, delivers a Flesch Readability Score, and much more

  • Advanced: $129/month unlimited keyword research, unlimited competitor research, 200 AI blog posts, 200 paragraphs of AI content.

Our take:

GrowthBar is one of the best AI writing tools out there. Growth Marketing Pro and a team of engineers and marketers have built GrowthBar over the last 2+ years. We’ve invested hundreds of thousands of dollars and thousands of hours into honing GrowthBar into the number one tool for content SEO.

2. Copy AI: Best for Teams

CopyAI is a short-form AI writing tool. 

It excels at generating short-form content such as email subject lines, blog title ideas, headlines, social media captions, product descriptions, brainstorming, bullet points, and almost anything else you can think of. It’s an optimal tool for teams with a lot of different writing use cases.

Like GrowthBar, Copy AI is built on GPT-3, making its results accurate and 100% unique.


  • Digital ad copy: Facebook Ads, Google Ads, LinkedIn Ads
  • Social media content: Instagram posts, Instagram hashtags, brainstorming topics, etc.
  • Website copy: hero text and meta descriptions
  • Ecommerce copy: product descriptions, product benefits, etc.
  • Sales copy for lead generation


  • Content templates: Copy AI comes with many templates (90+) and tones to choose from for all kinds of short-form content, such as emails, social media posts, and product descriptions.
  • Supported languages: Copy AI can translate to 25 languages, regardless of the chosen plan. 
  • Quality of support: In addition to the Help Center page on their website, Copy AI also has an easy-to-use messaging system to get in touch with their customer support team.

Companies using Copy AI:

Ebay, Nestle, Ogilvy, Microsoft


  • Free: Copy AI has a free plan that includes 10 pieces of copy, which won’t get you too far
  • Pro: $35/month, which gets you unlimited copy credits
  • Enterprise: no pricing information provided

Our take:

If you’re a growth marketer, social media marketer, salesperson, or almost any other content-creating function, Copy AI is a transformative tool. It enables you to make copy for almost anything you can imagine. As with most tools, it requires a little human editing to get your content perfect for customer consumption, but it’s really outstanding.

3. Grammarly: Best for Grammar

Grammarly is a writing app that helps writers find and fix mistakes before they publish their work. By now, you’ve probably heard about it. They recently raised venture capital at a $13 billion valuation!

The app is also notable for its contextual grammar tips, which help writers improve their writing skills. Grammarly’s AI system combines machine learning with a variety of natural language processing approaches, enabling users to correct characters, individual words, sentences and even paragraphs of text.

  • Grammar checker, word choice
  • Sentence rewrites
  • Tone adjustments
  • Plagiarism detection
  • Word choice
  • Fluency checker
  • Save snippets, create a tone profile, create style guides, and more with the business plan
  • Integrations with web browsers, desktop apps like Slack, Microsoft product suite, email clients, and more


  • Simple interface that works in your browser as Chrome Extension and desktop app so you can edit emails, Google Docs, and more
  • Grammarly’s free plan is very robust and includes punctuation, tone detector, conciseness checks and more
  • Grammarly is stupid simple to use

Companies using Grammarly:

The New York Times, The Wall Street Journal, USA Today, TechCrunch


  • Free: basic functions like grammar checker and punctuation errors
  • Premium: $30/mo, includes all free features plus word choice, fluency checker, tone adjustments, etc.
  • Business: Starts at $120/mo for 10 users

Our take:

If you’re writing lots of content, you should at least try the free version of Grammarly. I consider myself a good writer, but I can’t tell you the number of times I’ve found silly typos in my blog posts and emails using it. The business plan is useful for larger writing and content teams. There is no AI content generation, but as a writing assistant, Grammarly is second to none.

4. Jasper

Jasper is a relatively new tool that is somewhere between GrowthBar and Copy AI. It includes a number of short-form features, including product descriptions, blog post ideas, Google Ads, Facebook Ads, LinkedIn Ads, as well as a long-form content assistant that helps you write blog posts.

The product is slick and modern and very simple to understand/use.


  • Over 50 templates that produce AI copy including Facebook Ads, Google Ads, LinkedIn Ads, sales copy, social media copy, email marketing copy, and much more
  • Long-form content assistant that allows users to create full blog posts with AI assistance
  • Team collaboration features
  • Integrations with Grammarly and SurferSEO for support with grammar and search optimization on the fly (though, these add-ons get expensive)


  • Great suite of templates that rivals Copy AI in breadth
  • Large Facebook community for support
  • Works across 25 languages
  • Many help videos to get started

Companies using Jasper:

Airbnb, Promo, Autodesk, Keller Williams and Logitech


  • Starter: $29/mo, 20k words per month and access to all 50 templates
  • Boss Mode: $59/mo, 50k words per month, access to all 50 templates, plus Boss Mode (the long-form editor)

Our take:

Good product, but falls in between a long-form SEO tool (like GrowthBar) and a full suite of copy tools (like Copy AI). I took it for a spin and wrote some content. The AI outputs were fine, but far from perfect. Jasper also seems to include weird spacing in all of its outputs, which means more editing is required than I’d like.

5. Ink

Ink is an all-in-one text editing and SEO writing tool that makes it easy to find and publish high-quality content. With Inkforall, you can quickly find and curate content from around the web, and then publish it to your website or blog with just a few clicks. Plus, Inkforall’s built-in SEO tools help you optimize your content for the search engines, so you can write and rank simultaneously.

Ink also has some Grammarly-like features, in that it can instantly rephrase your content with a single click. And because there is a Chrome extension, you can use Ink anywhere you write. Finally, Ink has many features like Copy AI including PPC ad copy, call to actions, and more.


  • Long-form editor with SEO optimizations built-in
  • PPC copy and landing page text generations
  • Other content generations include video titles, bulleted text, product descriptions, domain name generations, AIDA copywriting, and more
  • Writing tools including noun checker, verb finder, parts of speech checker, paragraph counter, and more
  • Meta optimization 
  • Spelling and grammar suggestions 
  • Minimalist interface 
  • Image optimization — compression and resizing 
  • Sentiment analysis 
  • WordPress integration 


  • With 60+ functions, Ink is definitely one of the most comprehensive solutions on this list, as it includes grammar, long-form content, ads, and more
  • Native app for Mac, Linux, Windows, and Google Chrome
  • Simple to use and fantastic support documentation and videos

Companies using Ink:

Shopify, HubSpot, Uber and Salesforce


  • Starter: $8.80/month, 60+ AI writing functions, 222 Ink points, unlimited sentence rewrites, 1 user login, chat support
  • Pro: $44/month, 60+ AI writing functions, 555 Ink points, unlimited sentence rewrites, 1 user login, priority support, and SEO tools including headline optimizer and keyword research
  • Team: $177/month, 60+ AI writing functions, unlimited Ink points, unlimited sentence rewrites, 3 user logins, priority support, and SEO tools including headline optimizer and keyword research

Our take:

Ink is another all-around tool with many features like Copy AI. However, it actually has better SEO functionality than Copy AI and a superior long-form editor. For this reason, I put it in a similar category to GrowthBar in its utility for SEO content teams.

6. Rytr

Like Copy AI and Jarvis, Rytr is a jack-of-all-trades when it comes to creating copy. It uses AI to generate unique copy for a number of use cases, including business pitch ideas, brand names, calls to action, email, Facebook, Twitter, and LinkedIn ads, product descriptions, meta descriptions, and more. It’s a straightforward tool that generates unique copy in seconds.


  • 30+ use cases
  • 30+ languages
  • 18+ tones you can select from (convincing, awestruck, inspirational, etc.) to add personality to your content
  • API available


  • Uses scientific copywriting formulas — such as AIDA & PAS — to provide best quality output that requires minimal to no editing
  • Honed content outputs mean pretty reliable text generations
  • Very generous free plan

Companies using Rytr:

Freshworks, Ikea, Ford, Payoneer, PWC and Adidas


  • Free: $0/mo, generate 5,000 characters per month
  • Saver: $9/mo, generate 50,000 characters per month
  • Unlimited: $29/mo, generate unlimited characters per month

Our take:

Rytr is a good tool. The AI content outputs are generally error-free and the free plan is one of the strongest on this list. They also have a “lifetime plan” that has been advertised on AppSumo that is very affordable. For that reason alone it’s worth a spin. I think it’s one of the best tools for journalists and other long-form writers who aren’t necessarily as concerned with SEO suggestions.

7. Writesonic

Writesonic has developed a deep-learning artificial intelligence that is able to write articles in a fraction of the time it previously took. The AI is able to generate high-quality articles, blog posts, landing pages, Google ads, Facebook ads, emails, product descriptions, and more.


  • Website copy: headers, feature to benefit, landing pages
  • Digital ads: Facebook, Google, LinkedIn
  • Ecommerce: product titles, product descriptions, Amazon Ads, etc.
  • AI article writer similar to Jasper and GrowthBar


  • Writesonic is pretty comprehensive and has nearly as many functions as Copy AI
  • Semrush integration gives SEO recommendations that enable you to write Google-friendly copy

Companies using Writesonic:

Taskade, Mattressman, Schneider Electric, Evernote, and Salesforce


  • Free: 10 credits, all features, 1 seat
  • Basic: $15/month 100 credits, all features, 1 seat, long-form writing assistant, and Semrush integration
  • Professional: $45/month unlimited credits, all features, 1 seat, long-form writing assistant, and Semrush integration
  • Startup: $95/month unlimited credits, all features, 2 seats, long-form writing assistant, and Semrush integration, priority support
  • Agency: $195/month unlimited credits, all features, 4 seats, long-form writing assistant (with longer AI outputs), and Semrush integration, priority support

Our take:

Writesonic is a great all-around solution that has nearly as many functions as Copy AI. From my experience, the outputs are pretty well honed as well. I think it falls between an SEO AI tool and a comprehensive solution like Copy AI. Depending on your use case, it may be a strong solution.

8. Copysmith

Copysmith is the ultimate content generator for ecommerce businesses. It’s much like Copy AI — with a diverse set of use cases — but exclusively for ecommerce. Copysmith’s AI writing tools include Facebook Ads, LinkedIn Ads, Google Ads, product descriptions, blog ideas, ad ideas, YouTube video descriptions, and more. Content is created atop OpenAI’s GPT-3 — making the recommendations extremely human and accurate.

Copysmith has many different templates depending on the type of copy you want to generate. Generally speaking, each template format is very similar; you add keywords and other relevant information, then their AI does the rest. You end up with a list of short snippets of copy. Each piece of copy is unique, so you can either copy and paste it or make some edits.


  • Instantly generate high-quality AI content
  • Various copy types available: such as ads, meta descriptions, product descriptions
  • Original copy that will pass plagiarism checkers
  • Generate product descriptions for thousands of SKUs on Shopify, Amazon and any other platform
  • Team collaboration features: cut down on in-person collaboration time by tagging teammates for editing and deploying copy everyone agrees on


  • For ecommerce businesses so all copy is specifically geared towards click-through and conversion
  • Outstanding customer support

Companies using Writesonic:

Marshalls, Change.org, Google, Zapier


There are four different monthly pricing plans:

  • Starter: $19/mo
  • Professional: $59/mo
  • Enterprise: $499+/mo

Our take:

It only takes a couple of minutes to generate a list of copy ideas, and Copysmith’s AI reads flawlessly for the most part. And because they’ve niched into ecommerce, the tools are more developed for that use case — meaning this is the tool for you if you’re building an online store.

What Are AI Writing Tools?

The rise of artificial intelligence writing tools has made it possible for anyone with a word processor and an internet connection to produce their own AI-generated text. This is especially important for content marketing specialists and writers who are looking to cut down on their workload.

Many AI writing tools use some combination of open APIs like GPT-3 and their own technology to create human-like content at scale.

Of course, the use cases are varied: from short form Google Ads, Facebook Ads, and subject lines to longer form email copy, blog posts, and even novels.

AI writing tools aren’t perfect. Most of them require some amount of human editing to nail the tone and produce fully accurate information. Plus, if you’re spending millions of dollars on ads, I’d personally like to do a lot of my own finessing to make sure the final product is exactly what I intended.

But in general, AI writing tools are huge. At this point, nearly every business, agency and entrepreneur is using some form of AI content. It’s accessible, affordable and pretty accurate.

What are the Best Free AI Writing Tools?

As you’ve probably gathered, most of the tools on this list aren’t free… with one exception.

Copy AI actually has a number of free tools, like a bio generator, subject line generator, content idea generator, Instagram caption generator, and a few more.

Copy AI’s free tools are pretty cool, however, you’re limited to just a couple of tools and a few results each. Plus there is no long-form editor for creating blog posts. However, if you’re just dipping your toes into the world of AI writing, this would be an awesome place to start.

Copy AI’s blog post idea generator

Grammarly also has a great free product as well. You can download the Chrome Extension at no cost and there is a web version here that can perform simple grammar checks.


AI writing tools are groundbreaking technology that can produce content in any genre from any perspective. The emergence of natural language processing and specifically GPT-3 has opened a whole new world of tools that make the lives of writers, authors, journalists, content creators and SEOs much easier.

To summarize:

  • If you’re looking for an SEO content tool, look no further than GrowthBar
  • If you want a tool that can support a team and a wide variety of use cases, I recommend Copy AI
  • If you’re looking for a grammar-only tool, Grammarly is far and away your best bet
  • If you want the most affordable solution, Rytr will give you great functionality at the cheapest rate

If you’re writing a lot of content, you’d be wise to enlist an AI writing tool. The best ones can save you hours of planning and writing time, which will enable you to focus on other parts of your business.

    • Mark Spera

      You’ve got to try it yourself, Rony! I find AI writing very helpful for ideating and creating content. It’s not always 100% perfect — but with light editing you can create practically an entire post with a few button clicks.

  • Mark, this is a great roundup of AI software. I LOVE Jasper, I think it’s my favorite, paired with Surfer. I tried Copy.AI and had such high hopes but it didn’t do it for me. I was bummed. I trialed Growth Bar, and I loved how well it helped with the outline, much better than any of the others, for sure. Now, if we could just melt them all into one….💕
