#2 – Frase

Frase is an all-in-one AI writing platform with a rich feature set. It’s our top pick for content marketers thanks to its excellent content optimization suggestions and SEO tools.

Frase Homepage

Frase gives you more for your money than many of its competitors. It’s jam-packed with tools to help with every part of the content marketing process, from keyword discovery to content planning, writing, optimization, and beyond.

The AI writer is excellent and can generate pretty much every type of content. There are over 30 templates to choose from out of the box. 

And if you can’t find a template that does what you want in the native library, there are hundreds more community templates built by Frase users that you can use in a couple of clicks. Plus, you can even build your own custom AI writing templates.

Frase’s text editor is fantastic too. It comes with real-time content scoring so you can see how well optimized your content is for search as you write. To improve your score, you can follow Frase’s optimization suggestions, which are based on SERP analysis. 

Frase analyzes the search results for your target keyword to figure out what words/phrases and SEO best practices your top-ranking competitors use. Then, it uses this data to serve up optimization suggestions in the content editor.

Copy.ai is an AI content generator used by over 6 million professionals and teams. It can help you to create content 10x faster.

Copy.ai Homepage

Copy.ai supports lots of different use cases. You can use it to create blog content, ecommerce copy, digital ad copy, Instagram captions, YouTube video ideas, and more. There are over 90 tools and templates to choose from in total.

The best thing about it is how straightforward it is. It couldn’t be easier to use. First, you let Copy.ai decide what kind of content you’re looking to create. Then, you enter some points that you want to cover and choose a tone for the writing.

Copy.ai’s content generator will then serve up multiple pieces of content for you to choose from. You can select your favorite, then edit it in the built-in editor, and copy-paste it over to your CMS for publishing. That’s all there is to it.

  • High-quality content output
  • Wide range of supported content types
  • Generous free plan

#4 – Jasper

Jasper is another popular AI writing tool. It’s super powerful and versatile, with 50+ writing templates and high-quality output.

Jasper Homepage

The main reason Jasper is popular is because of the quality of the content it generates. In our tests, it consistently produced incredibly human-like written content that met the brief and required minimal editing.

Part of the reason for this high-quality output is likely because Jasper uses OpenAI’s GPT language prediction model, which is widely considered the gold standard when it comes to AI writing.

And the developers keep updating it to keep pace with advances in AI technology. Right now, Jasper uses GPT-4 to ensure the highest quality output.

We also really like Jasper’s user interface. It couldn’t be easier to use. To get started quickly, you can choose an AI template from the library. Templates are the building blocks of Jasper and are trained to generate specific types of content for different use cases.

For example, if you want to write a product description, choose the product description template and enter a brief prompt, and Jasper will do the rest.

If you’re trying to come up with ideas for your blog post, you can choose the blog post topic ideas template instead. There are also templates for blog content, social media posts, ads, artwork, etc.

You can open up your AI-generated content as a document in the built-in editor. It has an intuitive interface that’s pretty similar to Google Docs, so it’s super easy to work with. 

In the document editor, you can write and edit content like you usually would, but also utilize AI-powered tools to expand on your work, gather research, and rewrite/paraphrase sections as needed. This can help you create content 10x faster.

Other features we really like include Recipes (pre-built workflows that contain a series of AI commands), multi-language support, Surfer integration, collaboration tools, and Chrome extension.

Pros

  • Great quality content output
  • Easy to use
  • Well-designed editor
  • Good selection of templates 

Cons

  • Pricey compared to some other options

Pricing

Plans start from $49/month for 50,000 credits (words/month). Get started with a 5-day free trial with 10,000 credits. Save 17% with annual billing.

#5 – Sudowrite

Sudowrite is the best creative AI writing software. It’s been designed specifically for fiction authors and comes with a bunch of cool tools to help you to research, plan, and write your next novel using the power of artificial intelligence.

Sudowrite Homepage

Most of the AI writing software providers out there are geared toward content marketers—but Sudowrite is different.

Rather than helping you to write marketing copy and web content, Sudowrite is geared specifically toward creative writing (i.e. short stories, screenplays, novels, etc). So naturally, its feature set is totally unique.

Let’s say you’ve thought of a good idea for a story, but you’re struggling to figure out how to start. In that case, you can use the First Draft feature to get going quickly.

All you have to do is enter a brief description of the story arc and plot points you have in mind, and Sudowrite will generate a first draft that you can use as a jumping-off point.

If you’ve already made a solid start on your novel but ran into the dreaded writer’s block, you can use Sudowrite’s Write feature to break past that brick wall. It’ll read your story, then carry on writing the next 300 words for you in the same tone/style, like an awesome co-author.

If your story is very dialogue-heavy but thin on descriptions, you can use the Describe tool to flesh it out. You can even choose what sense you want Sudowrite to describe, and it’ll add a few lines to bring the readers into the story.

Other cool features include the Visualize tool, which generates AI art based on your character or scene descriptions; the Rewrite tool, which can rework your creative writing following common fiction-writing templates and best practices; and the Sudoreader tool, which reads your story and provides you with feedback about ways you can improve.

But our favorite feature of all is Canvas. It’s a powerful planning tool that you can use to plan out all your character arcs, themes, plot points, and more in a neat visual interface.

Pros

  • Great tools and templates for creative writing 
  • Interesting and intuitive interface 
  • Planning and brainstorming tools are helpful 
  • AI art generator 

Cons

  • Not the best if your want to write non-fiction or web content 

Pricing

Plans start from $19/month. There is also a free trial available. Save up to 50% with an annual subscription.

#6 – INK

INK is an AI writer and content marketing suite that puts safety first. Its built-in content shield makes it a good choice for marketers that are concerned about Google penalties.

INK Homepage

INK shares many of the same features as other AI writing software.

It can generate copy and content based on your prompts and help you to optimize your written content for search with SEO suggestions and scoring. It can also help you find keywords, plan your content strategy, generate images, and more.

But what makes it different from most of its competitors is that it places a lot of emphasis on avoiding Google penalties.

The thing is: When you use AI software to write content, there’s always a small risk that Google will be able to detect that your content hasn’t been written by a real human. Even worse, some AI tools may even generate spun content that Google flags up as plagiarised.

If that happens, it can land your website penalties that can severely harm your SEO and organic visibility.

To avoid that, INK comes with a nifty AI Content Shield feature that analyzes the text you’ve written/generated to test whether or not it’s possible to detect that it’s been written by AI. If it is, INK can rewrite it for you until it’s undetectable. Cool, huh?

Pros

  • Innovative AI content shield feature
  • Unlimited AI-generated content on all plans
  • Good variety of AI templates
  • WordPress integration

Cons

  • No free plan (only free trial)
  • Keyword research features are limited

Pricing

Plans start at $49/month. Get 2 months free with an annual subscription. A 5-day free trial is available with 10,000 words.

#7 – Writesonic

Writesonic is a popular AI writer, copywriting, and paraphrasing tool that’s powered by GPT-4. It has a huge library of AI tools and templates and does a great job of generating both short-form and long-form content.

Writesonic Homepage

Aside from the high-quality output, one of the best thing about Writesonic is how versatile it is. It offers a larger variety of AI tools than most of its competitors, so it can handle almost anything.

In total, there are over 100 tools/templates to choose from. Some of the most popular tools include the AI Article Writer (which generates long-form blog posts), outline generator, and product description writer. 

There are also templates for Facebook Ads, Quora Answers, Product descriptions, PAS copy, etc. 

Plus, there are a bunch of novel tools you don’t find on many other AI writers, like a ‘tone changer’ that can modify the tone of your writing, a song lyrics generator, and a review responder.

The UI is easy to get to grips with. You just choose your tool/template, and enter some instructions to let the AI know what you want to write about (e.g. target keywords, topics, etc.). 

You can also tailor the quality of the output, ranging from Economy to Ultra. Higher-quality content will sound more ‘human’ but will require more credits (the number of credits you can use will depend on your plan).

You can write and edit your content in Writesonic’s built-in Sonic Editor, which we really liked.

If you want to optimize your content for SEO, you can integrate your SurferSEO account easily.

Writesonic also comes with an image generator (Photosonic) and an AI chatbot (Chatsonic).

Pros

  • Excellent quality output
  • Great UI
  • Easy to use
  • Tons of content templates
  • Integrates with Surfer
  • Flexible pricing model
  • One-click publishing 

Cons

  • Requires Surfer integration for SEO tips 

Pricing

#8 – Quillbot

Quillbot is one of the best collections of free AI writing tools on the market. It includes a paraphraser, grammar checker, plagiarism checker, summarizer, and more.

Quillbot Homepage

The Quillbot paraphraser is a fantastic tool for when you just want to quickly rewrite your existing content. For example, you might use it to freshen up a blog post with new content or to create a variation of one of your social posts for a different platform.

All you have to do is paste the content in and hit Paraphrase, then copy the results to your clipboard.

But if you want, you can also change the paraphrasing mode to tweak the output. For example, there’s a mode to rewrite it in a more formal tone, and modes that expand on or shorten your content instead of just rewording it.

The Grammar checker is another super useful tool. Instead of manually proofreading and correcting each of your spelling and grammar errors one by one, you can just paste your content into Quillbot and click Fix All Errors, and it’ll tidy up the grammar for you.

The Summarizer can be used to condense long documents into concise paragraphs or bulleted sentences. And the Citation Generator can create full and in-text citations for your essays and other academic projects quickly and easily.

Aside from the above, QuillBot also offers a powerful AI Flow, Plagiarism Checker, and extensions for Google Chrome and MS Word.

Pros

  • Easy to use
  • Free web-based tools
  • Paraphraser is excellent

Cons

  • Lacks advanced features
  • Limited words on the free version

Frequently asked questions

What is AI writing software?

AI writing software is a tool that uses artificial intelligence to help you write better content, faster. 

This type of software is typically able to generate original, human-like content (i.e. blog posts, product descriptions, social media captions, etc.) based on your instructions/prompts. 

It may also come with other AI-powered writing and editing tools to help with your workflow. For example, the software may be able to rewrite paragraphs/sentences for you, improve your grammar, expand on your work, change the tone, etc.

How does AI writing software work?

AI writing software works by utilizing machine learning algorithms to generate human-like text based on a prompt given by the user. 

The technology behind this is complex. But typically, it involves training a type of artificial neural network called a transformer on a large dataset of existing content. 

During training, the model learns to ‘predict’ the next best word in a sequence based on the previous words. This ability to build up sentences predictively is what allows it to generate output that is nearly indistinguishable from content written by a real human.

Once the language model is trained, users can input a prompt, and the AI writing software will generate text based on what it has learned.

Different types of AI writing software may use specialized language models or training data so that the AI is capable of producing content that’s more suitable for their target use case.

Can AI writing software replace content writers?

Maybe someday, but not yet. 

Statistics show that 28.4% of SEO marketers think AI is their biggest threat, but those fears may be misplaced.

Right now, AI writing software isn’t quite sophisticated enough to replace content writers and SEO professionals entirely—you’ll still need to edit the output heavily to get it ready for publication. 

That said, it can be an incredibly powerful workflow tool that can significantly streamline the content writing process. And an AI rewriter tool can be the ideal solution to writer’s block.

Is AI content bad for SEO?

AI content isn’t bad for SEO, as long as you use it the right way. 

Google recently revised its Webmaster Guidelines to clarify that AI-generated content isn’t a problem as long as it’s used appropriately—heavy emphasis on that last part.

Basically, Google doesn’t like AI content that’s generated and published solely with the purpose of manipulating rankings. That’s classed as spam, and it isn’t good for SEO.

But when AI is used to provide genuinely valuable and helpful content for the end user, Google’s happy to rank it in search.

It’s also super important to remember that for content to be good for SEO, it must be 100% unique and original—duplicate content is bad.

And while AI writing software should be able to generate original content, at least in theory, we’d still recommend heavily editing it, rewriting sections, and adding some of your own content in order to make absolutely sure it’s totally unique.

If SEO is a top priority for you, you might want to check out these content writing tools for SEO.

Final thoughts

That concludes our guide to the best AI content writing tools.

There are lots of great options out there, and each has its own strengths and weaknesses. So, I’d recommend focusing on the features that matter most to you, then working backwards to find the best platform for your needs.

That said, you can’t go wrong with most on this list. Particularly Rytr and Frase.
