18. ChatGPT – Best for AI-Powered Research

ChatGPT AI writing tool

If there’s one generative language AI you’ve heard of, it’s probably ChatGPT. ChatGPT is run by OpenAI, the people behind the GPT family of large language models. GPT models drive many of the services mentioned in this article. ChatGPT is simply OpenAI’s own interface.

And that chatbot-style interface is ChatGPT’s stand-out feature. ChatGPT doesn’t have any templates. It doesn’t focus on particular writing tasks or styles of writing. You ask it a question or tell it something you want it to write. These are known as ‘prompts’. ChatGPT scours its enormous language model for examples that fit the prompt. And generates something (hopefully) relevant. All in a matter of seconds.

ChatGPT AI writing example

The big strength of ChatGPT is its open-ended versatility. You can ask for anything you want. Not just writing articles or marketing copy. People use it to learn languages, write code, invent games and more. You can be as detailed or vague with your prompts as you like. It also has a unique ‘dialogue’ format. Once a prompt is answered, you can ask follow-up questions.

What you get out depends on the quality of your prompts. And it can be hard to get the level of detail right for a very specific piece of writing. OpenAI has now introduced example prompts to help. 

All in all, ChatGPT is an AI text generator in name. But its best use may turn out to be as a search and research tool. If you want to use it to write a blog post, say, it’s useful for generating content ideas. But not so much for creating a polished finished product. 

ChatGPT Pros

  • Hugely versatile – will generate text in response to pretty much any question
  • User-friendly chatbot-style interface
  • ‘Dialogue’ with the chat AI lets you easily refine and improve answers
  • Free to use

ChatGPT Cons

  • Not easy to generate ‘print ready’ responses the first time of asking.

ChatGPT is free to use. ChatGPT Plus starts at $20 per month. The main benefit of paying is priority access to the LLM. Responses can be slow at peak times.

Best for: Generating ideas and speeding up content research.

19. Chibi AI – Best for Flexible Writing Support

Chibi AI writing software

Chibi AI bills itself as a platform to “augment your writing experience”. Its flexibility and list of features are impressive.

You can specify the content type, the topic and the audience. Then choose from dozens of options for tone, vocabulary, style and language. It supports 20+ languages.

Chibi AI editing example

If you would rather write yourself, you can still get AI help in the form of prompts. Prompts work in a similar way to the main document generator. But are designed for writing short sections of text. Next paragraphs, new sections, ideas for where to go next.

You can save prompts to reuse. Chibi also has a memory feature which learns from your writing style and the type of content you write. There’s a brainstorming tool for mapping out ideas and a scratchpad for notes to organise ideas as you write. Chibi comes with Grammarly built-in and a review tool sums up text improvements in seconds.

Chibi AI Pros

  • Flexible text generation or writing assistant options
  • Learns from your writing over time
  • High degree of customization
  • Affordable, straightforward pricing

Chibi AI Cons

  • Although it’s a flexible tool for all professional content writers, there are no SEO tools. 

Pricing starts at $9 a month. This includes 10,000 generated worlds and gives you full access to all tools. There’s a free trial of 2,000 words. 

Best for: Storytellers and general writers looking for flexible AI support.

20. ClosersCopy: Best for Niche Marketing Content

ClosersCopy AI writing platform

ClosersCopy is an AI writing tool designed for marketing copywriters. It combines AI text generation with SEO optimization tools. 

By far the biggest USP ClosersCopy has is the number of text-type templates it offers. It calls them frameworks. But what’s really cool is the fact that users can create their own. And then share them on the platform.

There are 700+ different frameworks available. Most of them are made by professional copywriters. This means it’s great for finding really specific templates. For blogs and longer articles, you can find separate frameworks for different sections. So frameworks for a blog outline, for a title, for an introduction and so on. You can piece different frameworks together on a page called a Workflow.

ClosersCopy also offers functional SEO tools like keyword auditing and planning. SEO results are provided in the editor as you write.

Another stand-out feature of ClosersCopy is that it supports 128 languages. So it’s a truly global AI copywriting tool. It also has great in-app support, with handy video tutorials. Plus an active community of fellow users.

ClosersCopy Pros

  • 700+ AI copywriting frameworks
  • Combines marketing-focused text generation with SEO
  • Supports 128 languages
  • Active community of professional copywriters sharing frameworks and providing support.

21. NeuralText – Best for Speedy SEO Content Creation

NeuralText AI writer

NeuralText is an AI writing tool that guides you through every step of generating content. From in-depth SEO prep through to final creation.

It starts with the topic you want to write about. NeuralText’s SEO tools run a search on top-ranking examples for related keywords. From these, they do all the heavy lifting on SEO analysis. Long-tail keyword discovery, with popularity and usage trends. Keyword clustering, and strategy suggestions for how to cover all those clusters.

Next, NeuralText uses this data to create content briefs. These include outlines with H1 and H2 suggestions, word count and target SEO score. Plus suggested ‘People Also Ask’ questions for FAQ sections. 

The final step is to generate content. NeuralText has 50+ templates or ‘formulas’ to choose from. The AI generator doesn’t create complete texts for you like some other platforms. But it does create suggested blocks to help you populate your brief.

The sum of all this is that it drastically speeds up the content creation process. But without sacrificing precision on SEO ranking. If you’re serious about SEO, you’ll need to track how your content ranks on SERPs. Find the best rank tracking software here.

23. Article Forge – Best for Creating Long-Form Content

Article Forge AI writing software

There aren’t many AI writing software platforms dedicated to long-form content. Article Forge is an exception. It’s an AI-powered long-form editor that specializes in content of 1500+ words. But you can customize the length for anything over 250 words.

Article Forge create a new article with AI

The basics of how Article Forge works are very straightforward. You provide a keyword or main topic for your article. And then flesh that out with more instructions, if you want to. You set an article length. And tell the AI about anything you don’t want to include.

From there, Article Forge will generate a complete article in minutes. Every article is created from scratch. No cutting and pasting from other content on the web. So it guarantees passing all plagiarism tests. You can also select an option to avoid AI writer detectors.  All articles are also created SEO-ready using latent semantic indexing (LSI). 

One of Article Forge’s best tools is its bulk article generator. So rather than approach a content plan one article at a time, you can implement a whole strategy at once. If you input a list of target keywords or keyword clusters, the bulk generator will create an article for each. There’s a built-in post scheduler and you can connect your WordPress site to automate publication.

Article Forge Pros

  • Creates long-form content in minutes
  • All articles are plagiarism-free and SEO-ready
  • Bulk creation for implementing content plans
  • Automated publication on WordPress

26. AI-Writer – Best for Avoiding Plagiarism Pitfalls

AI-Writer software blog writing

One of the concerns people have about AI text generators is plagiarism. We know these tools work by scouring the internet for copy and rewriting it. But how good a job do they do on the rewriting part? 

A lot of AI text generators now advertise some kind of anti-plagiarism tool. But as any professional writer knows, there’s one surefire way to counter plagiarism accusations. And that’s to properly cite all of your sources.

This is the unique proposition AI-Writer offers. It specializes in generating long-form content. But it also includes a full reference list of where it got its information from. This lets you check the wording to make sure there are no straight copies. You can use the references as citations for full disclosure of your sources. And you can fact-check everything in the draft.

AI-Writer interface create content

The generator itself is as easy as it comes. It will run on a single prompt. Or you can use the AI Tailor feature to add a headline, keywords, sub-topics and structure. 

AI-Writer also offers a rewriting tool. This is more for rewording full texts than improving writing. It’s useful for reusing the same content without duplication penalties. 

AI-Writer Pros

  • Simple long-form content generation
  • Full citations for all sources used in generating copy
  • Rewording tool to avoid duplication
  • Follow-up topic suggestions.

AI-Writer Cons

  • SEO options are basic compared to other platforms.

Pricing starts at $29 per month for 40 articles with 5000 words per article. There is a 1-week free trial with articles capped at 600 words.

Best for: Avoiding plagiarism with professional citation standards.

The Chrome plug-in similarly includes a ‘Reply’ feature. Paste in an email, and the AI will generate a suggested response. It also offers one-step article generation. All you have to do is type out a prompt and the AI will write a draft for you. You can adjust tone and style to match different purposes.

There is also an ‘Improve’ feature. This automatically corrects spelling and grammar. But it will also re-write inputted text to suit different style and tone settings.

ParagraphAI Pros

  • Free forever AI text generation and writing assistance
  • Super easy to use
  • Mobile plug-in for one-touch messaging
  • Automatic text correction.

Best for: Free AI text generation and writing assistance.

What is an AI Writing Tool?

An AI writing tool is a piece of software that can create or adapt text. This kind of software uses artificial intelligence (AI) technology to analyse ‘real’ texts written by people. And uses what it learns to write new, original texts. 

This can be applied to writing whole texts or parts of texts from scratch. Or for re-writing or suggesting improvements to existing texts. Broadly speaking, AI writing software tools can be put into 3 categories. Although there is a lot of crossover between them, many platforms offer more than one. The 3 categories are:

  • AI text generators
  • AI writing assistants
  • AI-powered SEO tools

How do AI writers work?

The term ‘AI writer’ is pretty vague. There are lots of different types of artificial intelligence. Calling something ‘AI’ doesn’t tell you much about how it works. So how exactly do AI writing tools work? 

AI writers fall under a category of artificial intelligence called Natural Language Processing, or NLP. NLP uses technology called Large Language Models (LLM). LLMs are algorithms that analyse how language works. They use a special form of Machine Learning called ‘Deep Learning’ to identify patterns of ‘real’ language use. And then generate text based on those patterns.

The ‘large’ part is important. The more real-life language examples the LLM is ‘trained’ on, the better it is at reproducing realistic text or speech.

The most famous LLM is OpenAI’s Generative Pre-trained Transformer or GPT model. It’s the LLM that powers most AI writers. It’s so successful because it’s also the largest LLM out there. The latest version, GPT-4, has reportedly ‘learnt’ 1.76 trillion language parameters. It has been said that this is the equivalent of reading every piece of text on the internet. 

Which AI writing tool is right for you?

Here are my final tips and recommendations to help you choose the best AI writing tool. First, decide on the type of AI writing tool that you need. Are you looking to generate content fast? Then prioritise text generation. Or are you looking to improve quality and accuracy? If so, a writing assistant may suit you better. And if SEO is a high priority, look for tools with keyword research and content planning. 

A lot of AI writing software mixes and matches tools of all 3 types. But you can still decide which are most important to you and pick accordingly. Then, pick a platform based on budget and functionality.

  • WriteSonic and Rytr are great for low-cost text generation. 
  • Frase adds solid SEO tools while still being affordable to small businesses.
  • Jasper is worth the extra investment if you want to generate ranking content reliably and at scale.
  • Surfer and Outranking are your best bets if SEO is your main concern.

Grammarly’s free text-checking tools are great for general text improvement. But for professional quality proofreading, you may want to go for ProWritingAid instead. Or if you are a creative writer, SudoWrite.

Best AI Writing Tools FAQ

Which AI writing tool is best?

The best AI writing tool depends on what you are looking for. There are hundreds of AI writing software platforms out there nowadays. They all have strengths and weaknesses.

You can group AI writing apps into 3 broad categories. AI text generators which create texts for you. AI writing assistants which correct and improve your writing. And AI SEO tools which help create ranking content. Start by deciding which of these functions matters most to you. Many platforms offer 2 or even all 3.

Range of features, cost, ease of use, writing limits and support for teams will all influence which platform is best for you. Our top picks are:

  • WriteSonic and Rytr are great for low-cost text generation. 
  • Frase has solid SEO tools while still being affordable to small businesses.
  • Jasper is a bit pricier tool to generate ranking content.
  • Surfer and Outranking are the best tools for search optimization.

Which AI tool helps in writing?

A lot of the best AI writing software is designed to support your own writing. Rather than generate text for you. Grammarly is the most famous example. Grammarly offers free spelling and grammar correction and basic improvement suggestions for clarity. On paid tiers, you get suggestions for improving fluency and engagement. And the GrammarlyGO tool rephrases or fills in gaps with AI-generated text.

Reword is a great AI writing assistant. It learns your style of writing over time and tailors suggestions accordingly. It’s also good for teams. ProWritingAid offers professional standard copywriting. QuillBot is a low-cost rewriting tool that paraphrases chunks of text to improve different aspects. 

Is AI writing free?

Yes, some AI writing software tools are free to use. The most famous example is ChatGPT. ChatGPT generates written responses to any question or prompt. It’s free to use and unlimited in terms of how much text it will generate. Another good example is ParagraphAI, which can be used on mobile to generate email and message responses. It’s also free to use.

In most cases, you find the quality of generated text better with paid platforms. Most AI writers have a free plan or trial you can test. The best AI copywriting tools you can test for free are Jasper, WriteSonic, Rytr, Reword, Growthbar, Scalenut, Outranking, and CopyAI.

Does Google penalize AI writing?

No, Google doesn’t currently penalize AI writing. Text created by an AI writer gets treated just the same as text written by a person in SERPs rankings. 

What matters is the quality and accuracy of writing. Where people can fall down is publishing AI-generated content without checking it. Like people, AI writers do get things wrong, they do make mistakes. It’s important to fact-check all AI-generated content. As well as check it makes sense and flows right.

Is Rytr free?

Yes, Rytr is free to start. It has a free plan to generate 10k characters a month. That includes using all of Rytr’s 40+ templates. You can use it to create a blog post, email content, product description, ad and web copy. You can also carry out SEO keyword research and generate content ideas and plans.

Is Jasper free?

What is the best AI tool for writing essays?

The best AI tools for writing essays include Rytr and CopyAI. Both are popular and high-quality general text generators. They include templates for essays. So the text generated has the right academic tone and essay format.

Jasper is another great all-around text generator with essay options. Other tools to check out include QuillBot. It has AI research tools and will auto-generate citations. So will AI-Writer, although it doesn’t have specific templates for essays.

Is it illegal to use AI to write an essay?

No, it isn’t illegal to use AI tools to write an essay. But many education establishments don’t allow their use on plagiarism grounds. That’s because AI content writing tools find and analyse existing pieces of writing on a topic. And then rehash them in new words. Without proper references, AI-generated text can fall foul of plagiarism checks.

Many AI tools now include plagiarism detection features. This is to make sure the wording hasn’t been pulled straight from other sources. But even with these, many schools, colleges and universities still won’t accept AI-generated work. They want essays and papers to be student’s original work.
Using AI writing software assistants to check and improve your essays is a different thing. Check with your school or university what their policy on those is.

Is Grammarly an AI?

Yes, Grammarly is an AI. It’s best known as an advanced spelling and grammar checker. Most word processors include these tools, but they aren’t AI-based. 

Grammarly does a lot more. It includes advanced checking and improvement tools for fluency and engagement. These are AI-based. It also includes GrammarlyGO, a set of AI-based paraphrasing and writing tools for short sections of text.
