Writing is hard, huh? 

When you aren't searching the web for synonyms, you're chasing down the subject matter expert for some juicy industry insights, or attempting to please the algorithm gods. 

Don’t we all need a writing assistant to lighten our load? And to remind us why we fell in love with this difficult profession in the first place?

Luckily for us, the market is choc-a-bloc with AI writing tools that can help us with everything from proofreading and detecting plagiarism to overcoming writer's block and optimizing text for search engines.

How to use an AI tool for writing?

The sky really is the limit as far as use-cases of AI writing assistants are concerned. I asked ChatGPT how AI could be used to write faster or make writing shine and it gave me the following list (which I had to meticulously edit, but I was still impressed).

Here are six common ways of using AI writing tools:

1. Text generation with writing assistants

AI writing assistants can generate full-blown texts from scratch on an enormous breadth of topics—from fiction writing to landing page copy and technical documentation. While some of the technical articles may not be as in-depth or as well-researched as those coming from an experienced writer, they can be a good starting point for small businesses with limited budgets, students struggling with their homework, or those just looking to quickly generate content. 

Fun fact: There are even AI writing assistants for developers. GitHub Copilot, for instance, turns natural language prompts into coding suggestions for 90 million programmers, nearly everyday.

2. Text completion with writing assistants

AI writing tools can complete sentences or paragraphs that you've started writing, providing suggestions for the next word or phrase. This autocomplete technology can help you write more efficiently and can be especially useful for tasks such as writing repetitive emails or canned chatbot responses which do not require a lot of creative input or thinking.

3. Text editing with writing assistants

Isn’t editing, especially editing your own work, a literal pain in the neck? Let AI writing assistants take it over. Most AI writing tools let you edit existing text to make it look more polished and professional. They do this by providing suggestions for grammar, style, and readability improvements.

4. Text summarization with writing assistants 

You can use an AI writing tool to summarize long pieces of text into shorter, more digestible chunks. This one’s a godsend for writers who want to quickly understand the main points of an article or a book, or for researchers who need to quickly review many papers. 

5. Text generation with specific styles or tone

If you’ve ever used Grammarly, you might know how it analyzes the tone of your writing to communicate if the text reads as formal, informal, serious, funny, etc. That’s not the extent of the ability of writing assistants, though. They can also write text that adheres to a specific style or tone. This can be useful for writers who want to ensure that their text is appropriate for a specific audience or purpose.

6. Language translation with writing assistants

Some of the more advanced AI writing tools, such as ChatGPT, can even translate text from one language to another. Writers who cater to a multilingual audience needn’t master the target language or outsource the job to a translator on the other side of the world. 

While the possibilities that these tools open up are endless, they do have some limitations. I address the limitations of AI writing tools in the conclusion to this blog, where I attempt to share my two cents on the all-important question of AI replacing human writers.

Is AI writing free?

For now, the question that must be on your mind is: Is AI writing free? Surely, all these splendid features cost a bomb, don’t they?

Well, yes and no.

There are hundreds of free tools, among them scores with tiers that are free forever (freemium) and dozens with free trials and free writing credits.  But most of the advanced features of AI writing assistants still remain behind paywalls. Also, the better a tool’s output quality, the more it will cost you.  

Nonetheless, our Content team tried out the top-rated AI powered writing assistants in the market for you. Our research led us to this list of 10 tools which can serve you best without burning a huge hole in your pocket. 

Which are the 10 best AI writing tools of 2023? 

Here are the 10 best AI writing tools and assistants you can try out in 2023.

1. Quillbot

Best for: Proofreading, plagiarism checking, and adding citations

There aren’t many writing assistants that allow you to start improving your text the moment you land on their website. This is one of the main features that sets Quillbot apart. 

You head to the website (or install the extension) and start typing, without needing to sign in or create an account. Of course, this is only true for the free version in which you can paraphrase up to 125 words in each instance and generate a summary for a maximum of 2500 words in one go. 

Top features

  • Citation generator to easily create APA, MLA, and Chicago style full and in-text citations
  • Grammar checker 
  • Plagiarism checker (only for Premium users)
  • Co-Writer, an all-in-one writing space that combines all of QuillBot’s tools in one location, acting as the writing assistant you always wanted
  • Dedicated extension for writing better on MS Word

2. OSlash

Best for: Templating and automating repetitive writing

Ever find yourself typing the same things over and over? Copy metadata, blog outlines, instructions for your editor (please, please don’t cut this out 😅) or graphic designer (insert image here) etc.? It bugs me so much more than not finding the perfect word while writing. 

Enter OSlash text expander. It lets me create templates for things I type out repeatedly (my snippets) and insert them where I want, in a few keystrokes. Like typing o/collab and having it expand into this email, for example.

Hi [First Name], This is Garima.

I am the Social Media Manager at OSlash. 

I am a big fan of your YouTube Shorts. And have been binging them everyday during lunch this week.

What a fun way to combine solid productivity tips with humor; can’t get enough.

I am reaching out to you to discuss a possible collaboration for an influencer marketing campaign.

Are you free for a 15-min chat some time this week?

Looking forward to it!

Best, Garima

3. ProWritingAid

Best for: Creative writers looking for an expert writing assistant

ProWritingAid is more than an ordinary writing assistant. Sure, it has all the essentials from a grammar-and-spell checker to a thesaurus. But it goes one step ahead to offer Premium users the equivalent of literary coaching.

While its long-form content capabilities aren’t top-notch, it is a handy tool to come up with social media copy, ad copy, product descriptions, slogans and taglines etc. when you’re scrambling to make that deadline.

Best for: Churning out high-quality, plagiarism-free, search engine optimized long-form writing

Easily one of the most powerful AI writing assistants ever, Jasper is not a completely free tool but still makes it to our list thanks to how good it is! It’s not all that surprising considering how Jasper has read most of the public internet and can come up with unique, high-quality content with far greater accuracy than most of its counterparts. 

Plans start at $40/month but you can enjoy a 5-day free trial with 10k writing credits.

8. WordTune

Best for: Rewriting, paraphrasing, and changing the voice/tone of your text

I came across WordTune a couple of years ago, right when it was launched on Product Hunt. It’s truly an “AI powered writing companion” especially for writers like me who are always struggling with one question. “How can I say this better?”

Now, I no longer have to rack my brains to figure it out. I have the WordTune Chrome extension installed on my MacBook. I can simply select the sentence I want to rephrase, press command + D and voila! I get 10 rewrites to choose from, in a jiffy. It’s also one of my most-used everyday writing tools.

Top features

  • Long-form rich-text document editor 
  • MS Word add-in 
  • Change the tone of your text to make it more casual/formal
  • Shorten/expand text to comply with word limits
  • Spices: Add more context to enrich your writing with analogies, fun-facts and more with Spices mode

9. Rytr

Best for: Beginners who want to try out an AI writing assistant 

I’ll be honest. My foray into the rabbit hole of AI writing assistants began with Rytr. The barrier to entry was low, the possibilities exciting. I could write up to 10k characters per month, access all the use-cases and tonalities and even detect plagiarism in the free plan itself. 

If you’re super new to AI writing assistants, I’d recommend you to start ryting with this tool. Starting at $9/month for the Premium plans, it’s an absolutely low-risk investment.

Top features

  • Choose from 40+ use-cases and 20+ tones
  • Plugins and Rytr API for smooth integrations with your apps and website
  • Continue Ryting: Auto-write the next sentences based on previous content
  • Create your custom use-cases (only in the Unlimited plan)
  • Access to premium Rytr community

  • Built-in SEO analyzer and plagiarism checker

10. Grammarly

Best for: Power users who write hundreds and thousands of words every day

I am including this one in the list despite a few misgivings and my occasional annoyance with its nonsensical suggestions. Grammarly has been correcting my text since 2017 and 90% of the time, it has helped my writing read a lot better, even without needing to upgrade to Premium. 

How? I prefer to work with the extension overlay—a tiny green circle with an arrow—that follows me around everywhere I write online, checking my spelling, pointing out grammatical errors, and suggesting tone/voice modifications according to my writing goals and target audience. 

But you can also turn off the overlay and work directly with its editor instead, copy-pasting the text you want to work with. 

Top features

  • Grammar and punctuation correction
  • Contextual spell-check
  • Style suggestions to improve content delivery
  • Snippets library to auto-insert repetitive text
  • Support across desktop and web apps, including docs, messages, and social media platforms
  • Usage analytics for discovering your writing trends and frequent errors

Choosing the write AI assistant to help you create compelling content isn’t easy, especially with new writing tools with better features coming up every month. It’s evident that you need to invest some time in doing your own research. 

I’d definitely recommend you to take advantage of the free tiers and free trials before committing to any one tool. A word of caution, though. These tools are supposed to be just your writing assistants. If you expect them to serve you perfect content on a platter, you might be disappointed.

Conclusion: Will AI take over content writing?

As someone who writes for a living, I sincerely hope not. And I also believe it’s not going to happen anytime soon. Here’s my simple explanation.

Writing something, anything, is not about the act of writing alone. More than scuttling across the keyboard, it’s about scuttling across your mind. 

There are a lot of things AI may already have mastered but original thinking is where we still retain the competitive advantage. Good writing is basically good thinking, communicated smartly.

While generative AI (such as ChatGPT) can get you unstuck and occasionally lend you an insight sourced from the data it has been trained on, it cannot lend writing the one thing that makes a piece stand out—experience. You can read more about learnings from writing with AI here

It would serve us well to remember that almost everyone in the world has access to these AI writing assistants. As a result, almost everyone can come up with similar-looking content. That might add neither perspective nor value to your piece. 

So, I am not scared about losing my job to AI, yet. Instead, I am going to happily embrace the technology and use its strengths to complement mine. In fact, I am just off to email my editor this piece with my o/feedback-request snippet from OSlash. What about you?
