TABLE OF CONTENTS
Best Overall
Grammarly is a powerful, all-around AI writing tool with real-time grammar and spell-checking, tone adjustment, and generative AI features. It can create anything from outlines to short stories based on your prompts and generate enhanced versions of your existing text.
Grammarly can spark ideas for brainstorming and modify writing tones for different contexts and audiences, making it ideal for various writing tasks. Additionally, you can upload files into the tool and have it analyze the writing or summarize lengthy content.
However, this artificial intelligence (AI) tool supports fewer languages than some competitors, which may be a drawback for multilingual users. Consider Rytr for an alternative with expanded multilingual capabilities.
Grammarly has a well-designed interface with a writing assistant that scores your overall writing and lets you tailor writing recommendations. You can use the generative AI to set your voice and style or check your content for plagiarism and AI writing without navigating to another page. The platform is customizable so you can configure certain elements and views to your preference.
Grammarly is the best overall writing tool on my list for its rich set of writing features and versatility. It is suitable for a wide range of users, from students to professionals. It also operates seamlessly across multiple platforms, including web browsers and desktop applications, providing real-time assistance wherever you work.

Best for Marketing and Sales Content
Copy.ai is an AI writing tool primarily used to create high-quality marketing and sales content. It has more than 90 templates for generating social media posts, email campaigns, and product descriptions. It also gives fresh ideas and suggestions to spark inspiration when creativity wanes.
Copy.ai’s Brand Voice feature enables you to tailor your content’s general tone and style, ensuring that all your written materials align with your brand identity. The platform also has a library of pre-made prompts and templates for easier content creation.
A notable downside of Copy.ai is its lack of a plagiarism checker. If you need a plagiarism detector, Grammarly is an excellent AI detector software to consider.
Copy.ai’s interface presents a variety of features and lets you choose from a selection of generative AI tools, including GPT-4 and Claude. It also has a textbox for interaction with the AI tool and a separate Editor for typing and modifying content. While these options provide functionality, they can be overwhelming, particularly since it’s necessary to understand the capabilities of each model to make the most of them.
I recommend Copy.ai for how its robust features streamline content creation. Its prompt library is a valuable starting point for new marketing and sales content writers, and its generous free version makes it accessible for small businesses.

Best for Paraphrasing
QuillBot is an AI-powered writing tool renowned for its advanced paraphrasing capabilities, which improve text fluency, clarity, and readability. It delivers multiple paraphrasing models so you can adapt the output to different contexts. It can translate text to over 30 languages and has a Citation Generator for academic writing. QuillBot Flow, its AI assistant, provides structured guidance to simplify writing projects.
While Quillbot offers sophisticated features, it sometimes misses grammatical errors on the first pass and may require additional corrections. Grammarly is a better fit if grammar accuracy is your priority.
QuillBot’s interface includes a sidebar that lists all its tools like its paraphraser, grammar checker, AI detector, plagiarism checker, and AI assistant. However, each tool has its tab, requiring you to switch between them to use various features — which complicates the workflow, as you cannot use all functionalities on the same page.
Additionally, QuillBot Flow is tucked away in its own tab, which takes you to a completely new page with its own set of options.
I picked QuillBot as one of the best AI writing tools because of its extensive features and accessibility. Its browser extensions and native mobile applications allow you to write flexibly across devices and on the go. In addition, its customer support channels, which include phone assistance, are a rare offering that sets it apart from competitors, delivering direct help when needed.

Best for Writing Factually Accurate Articles
Writesonic is a comprehensive AI writing tool that specializes in ensuring articles are factually accurate through real-time web search. Its AI Article Writer feature helps you create detailed content by simply providing a topic and specifying keywords, brand voice, and references to tailor the output to your preference.
The platform can also generate images and optimize content for search engines through keyword research and readability analysis. Chatsonic, its AI assistant, can also analyze files.
Writesonic’s free version, however, is quite restrictive, offering only 25 one-time credits — limiting your ability to fully explore its functionalities. If you want an AI writing assistant with a free tier that has extensive features, try QuillBot.
Writesonic boasts a clear layout and well-organized elements, making navigation intuitive. With its clean and unobtrusive design, beginners and experienced users alike can easily find the features they need.
Moreover, the platform’s image generation capability lets you create complementary visuals to complete your content without switching to another AI software. The platform also has enterprise-grade security features.
However, some of its main functionalities can be difficult to use. Customizing content, for example, involves several steps, as you must input numerous details for highly tailored results. Also, its plagiarism checker is hidden and only appears when you highlight text, making it less straightforward.

Best for Versatile Content Creation
Rytr is an AI writing tool for marketers, bloggers, and all-around content creators. It generates high-quality texts for anything, from articles and blog posts to poems and social media updates. You can also choose from a multitude of tones and use cases, making it adaptable to diverse needs. Rytr’s MyVoice feature facilitates personalized writing, while its plagiarism checker ensures writing originality.
The free version of Rytr is limited to only 10,000 characters per month, which may not suffice when dealing with larger projects. If you want an AI writing tool with a free version that supports larger text volumes, I recommend QuillBot.
Rytr houses a wide array of features to accommodate all skill levels, even non-writers. It has dropdown menus for selecting use cases and tones, as well as the option to add a custom voice for personalized output. When generating content, you can also adjust the creativity level and the number of content variants. Additionally, its text editor gives full formatting control so you can fine-tune the output.
However, as packed as this platform is feature-wise, the numerous options can be confusing for first-time users, making it less user-friendly.
I consider Rytr to be one of the top AI writing tools today because it combines efficiency and adaptability for diverse content creation needs. Its ability to quickly generate text is complemented by a wide selection of languages, tones, and use cases, making content creation easy for different industries.

Best for SEO Writing
Frase is an AI writing tool specifically made for SEO optimization to help content creators increase online visibility. You can select the type of content you want to create — such as blog posts or cold emails, for example — and specify the topic. Frase’s AI tool will then automatically compose SEO-friendly content for you. These outputs are customizable, allowing you to adjust the tone to formal, informal, persuasive, or friendly.
Frase can also analyze top-ranking pages to identify relevant themes and keywords so you can craft articles that are sure to rank well in search results.
It’s worth noting, however, that Frase lacks a built-in plagiarism detection feature. If you need a plagiarism checker with your AI writing tool, I’d recommend Writesonic.
Frase’s interface is uncluttered, with a visually pleasing color scheme that feels easy on the eyes. It presents only a handful of options that serve a clear and relevant purpose. It balances simplicity with customization, letting you adjust tone and format text. Frase’s customization tools are carefully selected for practicality, making the interface efficient.
I highly recommend Frase as one of the best AI writers because it simplifies writing SEO-focused content while providing a user-friendly interface. Compared to its competitors, it makes content writing and optimization easier so you can focus on the task without being overwhelmed by unnecessary complexity.

AI writing tools are equipped with important features that streamline the writing process and elevate content quality. Each feature contributes to boosting efficiency and meeting content quality standards.
Natural language processing (NLP) allows AI writing tools to interpret and generate human-like text by analyzing language patterns, context, and semantics. This enables the creation of coherent, contextually accurate, and engaging content. By simulating human writing, NLP ensures that the output aligns with the specific subject matter and your expectations.
With customizable tone settings, you can adjust your content style to match your desired voice, whether it’s professional, friendly, or persuasive. This is particularly important when writing for different audiences or platforms. For example, when you’re drafting an email, being able to tweak the tone ensures your message connects with the right readers.
Prompt adherence means that the AI writer closely follows the instructions. This helps keep the content focused and relevant to your needs and gets you precise outputs for complex writing tasks without having to spend a lot of time editing.
Summarizing text helps turn long documents, articles, or reports into shorter texts that highlight the main ideas and points without omitting key details. AI productivity tools with impressive summarization features are useful for creating executive summaries or quick content overviews and save time and effort by automatically pulling out the most important information.
The tool’s AI language support makes it possible to produce, translate, or edit content in various languages. This capability is a must if you want to communicate in a lot more ways and to a lot more people, promoting inclusivity and making information accessible to a wider audience.
To determine the top AI writing tools, I evaluated them based on five categories: core features, costs, security and compliance, customer support, and ease of use. These criteria cover the key factors that must be considered when choosing an AI tool to make sure it meets your writing needs.
My evaluation combined hands-on testing, vendor demos, and user reviews to gain a well-rounded perspective. While I aimed to be as accurate as possible, it’s important to consider that features and pricing can change frequently, so I recommend double-checking the latest details before deciding which tool is better for you and your business.
These details establish how successfully the tool can maintain a specific tone, meet formatting requirements, and process diverse input types. Tools that perform well in these areas give greater flexibility for different types of content.
