AI writing tools have become essential for anyone looking to improve their writing, whether it’s paraphrasing a research paper, refining an article, or simply making sentences flow better.
Quillbot is one of the most popular options, offering grammar checks, summaries, and paraphrasing tools to streamline the writing process. However, if you’ve used it for a while, you might have noticed some limitations. It can be slow at times, and while the paraphrasing is helpful, the sentence flow isn’t always natural. Occasionally, it misses the intended tone or rewords sentences in a way that feels off.
Meanwhile, Cowriter offers a more advanced approach, providing smoother paraphrasing, better contextual accuracy, and a wider range of features to enhance your writing experience. But is it actually the better choice? In this guide, we’ll compare Quillbot and Cowriter side by side to see which one delivers the best results. Plus, we’ve put together a free PDF comparison guide so you can explore the differences for yourself.
Let’s get into it.
Quillbot Overview
Quillbot is one of the most well-known AI-powered writing tools, designed to help users with paraphrasing, grammar correction, and content refinement. It’s widely used by students, writers, and professionals who need to rephrase text, improve readability, or generate summaries quickly.
But it doesn’t stop at paraphrasing. Quillbot also includes:
- Detecting and correcting grammar errors
- Checking for plagiarized texts
- Summarizing sentences
- Generating citations in different styles
The platform offers several writing modes that let you adjust tone and style —so you can make your writing sound more formal, creative, concise, or fluent, depending on what you need.
Quillbot provides an easy-to-use platform with a range of helpful features for anyone looking for a quick way to enhance their writing. Now, let’s take a closer look at what it offers
Quillbot Features
Quillbot comes with a range of AI-powered editing and proofreading tools designed to help writers improve their content. Here’s a breakdown of its key features and how they work:
Quillbot Paraphraser
The paraphraser is Quillbot’s most popular tool, allowing users to rewrite sentences while maintaining their original meaning. It’s easy to access, sitting right at the top of the toolbar, and requires just a few simple steps to use.
To get started, tap the Paraphraser icon, then paste or upload your text into the editor. Quillbot will instantly generate a reworded version, helping you refine your writing without changing its intent.
With Quillbot’s paraphraser, you can rewrite a sentence as many times as needed until you’re happy with the result. However, free plan users have a word limit—you can only paraphrase up to 125 words at a time unless you upgrade to a premium plan.
The paraphraser also includes a synonym bar, which lets you control how much the text is changed. Moving the slider to the left keeps the rewording more accurate while shifting it to the right increases variation by replacing more words and phrases. This gives you the flexibility in how much you want your content to be modified.
You can also switch your texts between different modes when using the paraphrase. The modes help you to change the style and tone of your sentences. Let's see the different tones on Quillbot next.
Quillbot Modes
Quillbot gives you nine different paraphrasing modes, but if you’re on the free plan, you can only access the Standard and Fluency modes. Each mode tweaks your writing in a different way, helping you match the tone and style you need. Here’s what they do:
- Standard – Rewrites your text while keeping the original meaning intact.
- Fluency – Ensures your writing is grammatically correct and easy to read.
- Humanize – Makes your text sound more natural like a person wrote it.
- Formal – Adjusts your writing to sound more serious and professional—great for work or academic papers.
- Simple – Breaks down complex sentences into clear, easy-to-read language.
- Creative – Adds originality and variety to make your writing more engaging.
- Expand – Stretches out your sentences by adding details for extra clarity.
- Shorten – Cuts out unnecessary words to make your writing more concise.
- Custom – Lets you set your own paraphrasing preferences to match your style.
These modes give you the flexibility to fine-tune your writing to preference.
Quillbot Plagiarism Checker
Quillbot’s plagiarism checker scans your text to detect any duplicate words or phrases that may need proper citation. This feature is especially useful for academic writing, helping you ensure that all sourced content is correctly credited.
However, the plagiarism checker is only available with a premium subscription. Even with a paid plan, you’re limited to 20 pages per month, unless you purchase additional scans.
If you’re an article writer or someone who needs to check multiple documents regularly, this limit can be restrictive. In that case, you might find other tools like Cowriter more practical. Even in its free version, you get a standard plagiarism checker and a sophisticated plagiarism detector in its premium version.
Quillbot Grammar Checker
Quillbot’s grammar checker helps you catch and fix spelling mistakes, punctuation errors, tense issues, and more. You can use it after paraphrasing your content or paste in an original text for a grammar check.
Once you run your text through the tool, it highlights mistakes and suggests corrections, which you can approve with a click.
However, it’s not the most thorough grammar checker out there. Some mistakes might slip through, and the suggested fixes may not always be perfect. If you need deeper proofreading, you might want to double-check your work with a more advanced tool like Cowriter.
Quillbot AI Detector
Quillbot’s AI detector helps you check whether a piece of text was likely written by an AI. This feature is useful for students, educators, and content creators who want to ensure their writing sounds human.
Using the tool is simple; just paste your text, and Quillbot will analyze it and provide a percentage score indicating how much of it appears AI-generated.
It is a pretty decent AI checker, but some users have reported that their completely human-written work was flagged as AI-generated, while others found the tool inconsistent compared to dedicated AI detectors.
Quillbot Citation Generator
Citing sources correctly is essential in academic writing, and Quillbot’s Citation Generator makes the process easier. Instead of manually formatting your references, you can use this tool to generate citations in the correct style with just a few clicks.
Quillbot supports multiple citation formats, including:
- APA (American Psychological Association)
- MLA (Modern Language Association)
- Chicago Style
You can enter a website link, book title, or other source details, and Quillbot will automatically create a properly formatted citation. This is especially useful for students and researchers who need to ensure accuracy and stay updated with the latest citation rules.
Quillbot Summarizer Tool
If you need to condense a long article, report, or essay without losing key information, Quillbot’s Summarizer Tool can help. It shortens text while keeping the main points intact, making it useful for students, researchers, and professionals who want quick summaries.
You can control the summary length using a slider, allowing you to decide how much detail to keep. The tool offers two summarization modes:
- Key Sentences: Extract the most important points from the text and present them as bullet points.
- Paragraph Mode: Generates a condensed version of the content in full sentences while maintaining readability.
This tool is handy when you need to quickly understand long-form content without reading everything in detail.
The summarizer does not rewrite sentences. Instead, it picks what it considers the most important parts and removes the rest. While this can be helpful, the results aren’t always accurate or reliable. Sometimes, crucial details are left out, making the summary incomplete or missing context.
Quillbot Flow
Quillbot Flow is an all-in-one AI writing assistant designed to help you organize, research, and refine your writing in a single workspace. Instead of switching between multiple tools, Flow brings everything; paraphrasing, summarizing, citations, AI-generated suggestions, and even plagiarism checking into one place.
You also get access to integrated research tools that allow you to gather sources and take notes within the same space. Plus, with built-in citation management, formatting references becomes much easier.
For those who need a more efficient workflow, Quillbot Flow minimizes distractions by keeping all writing tools in one place, making it a useful option for students and professionals alike.
Quillbot Free Version
Quillbot offers a free version that gives you access to essential writing tools without needing to enter payment details. With a free account, you can use the paraphraser, summarizer, citation generator, grammar checker, and Flow, making it a decent option for casual users.
However, the free plan comes with significant limitations. The paraphraser only rewrites 125 words at a time, the summarizer processes up to 1,200 words, and you won’t have access to the plagiarism checker. These restrictions can be frustrating if you do a lot of writing, especially for academic or professional purposes.
Upgrading to the premium version is a better option if you need unlimited access and advanced features. The pricing is reasonable and can be a worthwhile investment if you write frequently.
Quillbot Premium Version
If you're looking for unrestricted access to all of Quillbot’s features, the premium version offers flexible pricing plans to fit different budgets. Unlike the free plan, the premium version removes limitations, allowing you to paraphrase unlimited words, summarize longer texts, and use the plagiarism checker.
Quillbot's pricing is affordable and flexible, with options to pay monthly, semi-annually, or annually depending on your needs. Here’s how much each plan costs:
- Monthly Plan: $9.95/month – Best for short-term users who need premium features for a limited time.
- Semi-Annual Plan: $39.95 (equivalent to $6.66/month) – A good option for users who want a longer commitment at a lower price.
- Annual Plan: $49.95 (equivalent to $4.17/month, billed yearly) – The best value for long-term users who want the lowest cost per month.
Cowriter Overview
If you’ve ever struggled to put your thoughts into words or needed a writing tool that goes beyond simple paraphrasing, Cowriter might be exactly what you're looking for. It’s an AI-powered writing assistant designed to help you generate, refine, and improve your content effortlessly.

What makes Cowriter stand out is its ability to understand context, tone, and structure, ensuring that your writing sounds natural and polished. Whether you're writing an essay, a blog post, or even a professional email, Cowriter acts as a smart collaborator rather than just a tool. It doesn’t just change words, it helps you write better sentences and organize your ideas.
Another big advantage is it’s built for more than just paraphrasing. Cowriter assists with brainstorming, structuring, and even generating fresh content when you’re stuck. That makes it your writing partner rather than just an editing tool.
Let's explore it's features:
AI-Powered Writing Assistance
Cowriter’s AI-powered writing assistance is designed to make your writing process smoother and more efficient. Instead of staring at a blank page, struggling to find the right words, you get real-time suggestions that help you refine your ideas and structure your sentences better.
Whether you’re working on an essay, a blog post, or even an email, Cowriter analyzes the context and offers intelligent suggestions to improve clarity, coherence, and flow.
Cowriter actually understands what you’re trying to say and enhances your text without making it sound unnatural. This makes it a great option if you want high-quality, polished writing without spending hours editing.

This feature is perfect for students working on assignments, professionals creating reports, or writers looking for inspiration. Instead of struggling with writer’s block, you get a solid starting point that you can refine as needed.
What sets Cowriter apart is its ability to generate meaningful, context-aware content. The text flows naturally, making it easier to edit and finalize without spending hours fixing awkward phrasing.
Anti-AI Detection Capabilities
If you’ve ever worried about AI detectors flagging your work, Cowriter can help. Its writing engine is designed to produce content that reads naturally—just like something you’d write yourself. This means you can generate text without it sounding robotic or triggering detection tools.
Cowriter achieves this by using advanced Natural Language Processing (NLP) to ensure its output flows smoothly, maintains proper context, and feels human-written. Unlike other AI tools that follow predictable patterns, Cowriter keeps your writing undetectable while still delivering high-quality results.
For students, professionals, and content creators who need AI assistance without the risk of detection, this feature is gold.
Paraphrasing Tool
Cowriter’s paraphrasing tool helps you rewrite sentences while keeping the original meaning intact. This feature makes it easy to simplify complex text, refine awkward phrasing, or improve readability.
Unlike other paraphrasing tools that just swap out words with synonyms, Cowriter focuses on natural flow and clarity. It restructures sentences intelligently, ensuring the output sounds human-like and fits your intended tone.
You also get control over the level of changes, whether you want it casual, persuasive, bold, friendly or academic. This makes it useful for students to avoid unintentional plagiarism, professionals refining reports, and content creators to make their writing more engaging.
Cowriter AI Text Humanizer
Cowriter’s AI Text Humanizer helps you take AI-generated content and make it sound like something a real person would write. If you've ever used an AI tool and felt that the text was robotic or unnatural, this feature fixes that. It rewrites sentences with better flow, adjusts word choice, and ensures your content feels engaging and human-like.
This is especially useful if you want to avoid AI detection or simply want your writing to sound more natural. Instead of spending time manually editing awkward phrasing, you can let Cowriter refine your text instantly while keeping your original message intact.
Auto-Next Paragraph Prompter
The Cowriter’s Completion Suggestions feature helps you finish your thoughts without getting stuck. As you type, it predicts what you might want to write next and offers suggestions to complete your sentences. This is great for overcoming writer’s block, speeding up your writing process, and maintaining a smooth flow of your content.
Unlike basic autocomplete tools, Cowriter’s suggestions are context-aware. It doesn’t just throw in generic phrases—it understands the tone and structure of your writing, making its recommendations feel natural and relevant. Whether you're working on an article, an essay, or even an email, this feature helps you write faster and with more confidence.
Cowriter Citation
Cowriter includes a built-in citation tool to help you properly credit your sources without hassle. Whether you're writing an academic paper, a research article, or a blog post that requires references, this feature ensures you format citations correctly in just a few clicks.
It supports multiple citation styles, so you can easily switch between APA, MLA, Chicago, Turabian, Vancouver, CSE, AMA, IEEE, and more. Instead of manually formatting your references, you just input your source, and Cowriter generates a properly formatted citation instantly. This saves time and reduces the risk of errors in your bibliography, making it especially useful for students, researchers, and professionals who need accurate citations in their work.
Cowriter Opposing-Argument Writer
Cowriter’s Opposing-Argument Writer helps you strengthen your writing by generating well-reasoned opposing viewpoints. Whether you're writing an essay, debate, or research paper, this feature ensures you consider different perspectives, making your argument more balanced and persuasive.
You simply provide your main argument, and Cowriter suggests logical counterpoints with supporting details. This not only helps you refine your stance but also makes your writing more compelling and well-rounded.
Cowriter Pricing
Cowriter is a premium writing tool designed for professionals, researchers, and students who need advanced writing assistance. It is built with cybersecurity principles, AI detection bypassing, and academic-focused tools that go beyond simple paraphrasing.
There is a free version that provides access to basic writing tools. It is suitable for casual writers but lacks the advanced features needed for serious work.
The paid plans include:
- Pro Plan – $20/month when billed monthly. Choosing the annual plan reduces the cost by 40%, bringing it to $11/month.
- Premium Plan – $385/month when billed monthly. Opting for annual billing cuts the price by 40%, making it $231/month.
These plans unlock all of Cowriter’s features, including the Anti-AI detector checker, plagiarism checker, citation generator, grammar checker, opposing-argument writer, and academic formatting builder. It is specifically designed for research, thesis writing, and professional content creation.

Head-to-Head Comparison: Quillbot vs. Cowriter
When choosing an AI-powered writing tool, it’s essential to compare features beyond just paraphrasing. Quillbot and Cowriter cater to different needs, with Quillbot primarily focusing on rewriting text and Cowriter offering an advanced suite of writing tools for academic, creative, and professional work. Here's how they compare:
- User interface and experience
Features | Quillbot | Cowriter |
Ease of Use | Simple and beginner-friendly.
Tutorials are available. | Intuitive and designed for both casual and advanced users. Tutorials are also available. |
Dashboard Organization | Focuses primarily on paraphrasing and grammar tools. | Well-structured, featuring a full library of writing tools. |
Workflow Efficiency | Suitable for quick edits and rewrites. | Offers a complete writing assistant that enhances workflow from start to finish. |
- Paraphrasing Capabilities
Quillbot’s paraphraser works well for basic rewrites but has limitations. The free version caps at 125 words, making it inconvenient for longer texts. While it maintains sentence structure, the output often looks too similar to the original. Increasing the synonyms slider changes more words, but it can distort the meaning and reduce accuracy.
Cowriter, however, allows over 200 words at once and adapts based on the selected tone. It doesn’t just swap words, it refines sentence flow and clarity while keeping the meaning intact. The result is a smoother, more natural rewrite with fewer manual corrections needed.
- Grammar and Style Improvement
Quillbot does a decent job fixing basic grammar mistakes, like punctuation errors and subject-verb agreement. However, it lacks depth in style enhancement, often missing nuanced improvements in clarity and sentence flow. It suggests changes, but they can feel mechanical.
Cowriter goes beyond basic corrections. It analyzes sentence structure, improves readability, and refines tone based on context. Instead of just fixing errors, it enhances writing fluency, making the text sound more polished and professional.
- Plagiarism Prevention
Quillbot offers a plagiarism checker, but it’s a separate paid feature that isn’t included in the free or basic premium plans. It scans documents for copied content but relies on limited sources, making it less reliable for in-depth academic or professional use.
Cowriter, on the other hand, includes a built-in plagiarism checker as part of its writing suite. It scans against a broader database and integrates with its AI writing features, ensuring both originality and proper citation. This makes it a more convenient and cost-effective option for students, researchers, and professionals.
- Additional Writing Tools and Features
Feature | Quillbot | Cowriter |
Citation Generator | Available in premium version. | Included in all plans. |
Auto-Next Paragraph Prompter | ❌ | ✅ |
Opposing Argument Writer | ❌ | ✅ |
Academic Format Builder | Basic formatting tools. | Complete academic structuring for research and thesis writing. |

Free Version | Basic paraphrasing with limited word count. | Includes essential writing tools for casual writers. |
Value for money | Best for simple rewrites but lacks advanced tools. | Offers AI-powered writing, grammar, plagiarism checking, and creative assistance in one package |
Quillbot is a solid choice if you only need basic paraphrasing and grammar correction. However, Cowriter stands out as a complete writing assistant, offering advanced AI writing tools, AI detection bypass, plagiarism prevention, and support for creative and academic writing. If you want more than just a rewording tool, Cowriter is the clear winner.
