Hero Image for QuillBot review

Using an AI writing assistant is a great way to speed up the writing process and fix any typos or grammatical errors along the way. 

QuillBot is one of the leading AI writing assistants offering a free and Premium version, but is it the best writing assistant for you? This article evaluates QuillBot, explaining each of its features with pros and cons so you can make an informed decision. 

But first, what is QuillBot, and how does it work?

What Is QuillBot?

QuillBot is a tool that uses artificial intelligence to help with the writing process. It’s well known for its ability to paraphrase sentences, but it also has features to correct grammar and punctuation errors, summarize information, conduct research, cite sources, and check for plagiarism. 

The tool supports students with academic writing, but it’s also used by professionals. QuillBot increases productivity and ensures quality by speeding up writing, researching, catching mistakes, and helping with writer’s block.

Features of QuillBot

QuillBot has several features and customizable elements that help you speed up the writing process. 

When you enter the editor, there’s a panel giving you access to eight tools.

Each of these features can be accessed individually, but if you want them all in the same tool, QuillBot Flow is what you’re after.

In the next section, we’ll break down each one so you can get a better understanding of the features.

QuillBot’s Paraphraser 

Paraphrasing is QuillBot’s primary function. You can input text into the tool and hit “Paraphrase.” On the right-hand side, your paraphrased text will populate. QuillBot underlines words and phrases and offers suggestions to replace text with synonyms or paraphrased sentences. 

The editor has several customizable options. Choose from nine different writing styles, such as Academic, Formal, and Humanize—though only Standard and Fluency are available with the free version. 

QuillBot allows users to select between American English, Canadian English, British English, and Australian English to accommodate for different spellings.

You also have the option to use the Synonyms tool to adjust how closely you’d like the paraphrased text to resemble the original text you entered.

You can paraphrase up to 125 words with the free version. If you need to paraphrase more than that, you’ll need to upgrade to Premium.

QuillBot’s Grammar Checker

The Grammar Checker is a great tool to catch any grammatical errors that have slipped through the net. Once you input text, QuillBot highlights errors in red and offers suggestions to correct grammar, spelling, and punctuation mistakes. 

With each suggestion, QuillBot explains what correction it is making, but the tool doesn’t go into much detail about why it needs correcting. 

If you want to learn more about the errors or to find examples, you’ll need to conduct your own research.

Much like Google Docs and Microsoft Word, you can work within the platform and add styling elements, such as changing the size of text, bolding words, or even adding italics. It’s not possible to add images, diagrams, links, etc., so if this is something you need, another tool may be more suitable.

QuillBot’s Plagiarism Checker

The Plagiarism Checker is bundled into the Premium plan and allows you to check up to 25,000 words per month at a cost of $19.95. 

Make sure your word count isn’t over this before you decide to purchase, especially if you’re writing a dissertation. 

If price is important in your consideration, ProWritingAid offers 20,000 words (or ten checks) for $10, so you may find this is a better value depending on your specific needs. 

QuillBot’s AI Detector

Paste or upload your text in English, French, German, or Spanish to check for AI written content by tools such as ChatGPT or Gemini. After scanning your text, you get a breakdown of:

  • % AI-generated

  • % AI-generated & AI-refined 

  • % Human-written & AI-refined 

  • % Human-written 

The tool will check 1,200 words for free, and if you need more, you’ll need to upgrade for an unlimited word count. It’s important to note the tool isn’t 100% reliable and can produce false results.

QuillBot’s Summarizer

The Summarizer is a neat little tool that allows you to shorten text, such as long emails or work documents, into their core concepts. You can select “Paragraph” if you want a paragraph or “Bullet Points” if you just want bullet points. 

QuillBot’s free version allows you to summarize up to 1,200 words, while the Premium version has a limit of 6,000 words. If this is a deal-breaker, you might be better off trying other tools with no limits.

In summary (no pun intended), it’s a useful tool to save you time reading, but there’s no guarantee you won’t miss out on the finer details.

QuillBot’s Translator

QuillBot lets you instantly translate text into 45 different languages, including French, Spanish, Russian, and Chinese. In the Translator, there is a 5,000-character limit, which is larger than Google Translate, and the tool is completely free to use without advertisements. 

The translation quality is good, and when you combine it with the other tools that QuillBot has, such as the Paraphraser and Grammar Checker, it can be very powerful.

It is worth mentioning, only 26 languages are available within the Paraphraser and only 6 in the Grammar Checker.

QuillBot’s Citation Generator

The Citation Generator allows you to look up references for books, websites, and journals so you don’t have to spend time manually creating them. You can select the citation style you require, like MLA and APA, and then you can copy and paste the citation where you need it.

The tool’s use extends beyond books and online journals. You can also reference videos, dictionaries, and reports. Students and academics will get lots of use out of the citation tool, especially when writing large pieces, such as a thesis, dissertation, or research paper. 

QuillBot Flow

This is the all-in-one tool QuillBot offers if you don’t want to switch between tabs. You can paste your text straight into the tool or upload an existing file. QuillBot Flow is a blend of all the tools with additional handy features, such as Suggest Text and Flares.

Suggest Text provides you with suggestions on what to write next based on QuillBot’s AI capabilities, while Flares provides prompts on how you might want to generate content. If you plan to use these features often, be careful because AI content detection tools might pick up that the writing was done by a computer. 

QuillBot’s Extensions and Desktop Apps

If you want to access QuillBot without having a tab open, you can download the Chrome extension or Mac app. This enables the tool to work in the background, and it’s compatible with most website applications, such as Google Docs, Facebook, X, and LinkedIn.

QuillBot also has a specific add-on for Google Docs and Microsoft Word if you prefer to limit it to the apps where you work.

Pros of Quillbot

Image of QuillBot pros

The best thing about QuillBot is that it’s quick and easy to use. There’s a minimal learning curve, so you can go straight into testing the tool. 

QuillBot has high quality paraphrasing and grammar checking tools that can help you speed up writing and editing. 

The free version of the tool gives you the opportunity to explore the different features. And if you have a paid plan, there are multiple writing modes available to suit your needs. 

Finally, QuillBot offers extensions so you can use the tool online without having to switch tabs or download the desktop app.

Cons of QuillBot

QuillBot cons

Although QuillBot is an affordable tool with plenty of features, paraphrased text still needs a manual check as the suggestions don’t always sound like a human wrote them. 

If you are planning to use the tool to churn out large amounts of work in a short time, be aware that the tool won’t always pass AI content detection checks. Make sure you always review work before submitting. 

As with all freemium software, there are limitations in the free version. The Paraphrasing tool lets you paraphrase up to 125 words at a time and restricts you to two writing modes: Standard and Fluency. 

So if you’re a copywriter and want to use the Creative writing mode, you’ll need to pay for Premium before you can understand how you might benefit from the tool. Premium is also necessary to unlock the full potential of the Synonyms tool.

The Plagiarism Checker is only available in the Premium version and allows you to check 25,000 words per month.

QuillBot’s AI Detector allows you to check 1,200 words in the free version, and Premium will grant you access to unlimited words.

The Summarizer allows you to summarize 1,200 words in the free version and 6,000 in the Premium version.

You can translate into 45 languages using QuillBot’s Translator, but it misses some languages, such as Catalan, and doesn’t let you differentiate between dialects such as Spanish from Latin America or Spain. There’s a limit of 5,000 words, which is more than Google Translate, but you will still need to split up lengthy translations.

While QuillBot does offer an AI review of your content (in Beta), the word count is limited to 5,000 words, and suggestions only scratch the surface. If you need more in-depth analysis and feedback, or if you need feedback on more lengthy writing, such as a book, there are better tools out there.

Last but not least, QuillBot gives you limited insight into how to improve your writing. It’s important to understand how to write effectively and avoid mistakes to reduce your reliance on writing tools.

Is QuillBot Free?

QuillBot provides free access to the Paraphraser, Grammar Checker, AI Detector, Summarizer, Citation Generator, and Translator. However, as covered in the previous section, there are limits in the free plan.

  • The Paraphraser allows up to 125 words

  • Writing modes are limited to Standard and Fluency

  • The Synonyms tool is restricted

  • Advanced grammar suggestions are behind a paywall

  • The AI Detector is restricted to 1,200 words

  • The Summarizer is capped at 1,200 words

  • The Translator is limited to 5,000 words

With Premium, you remove the limit of 125 words in the Paraphraser. You can unlock additional writing modes, like Creative and Academic, and make use of plagiarism checks. You also gain full access to the AI Detector, Synonyms tool, and the limit on the Summarizer increases to 6,000 words.

If you want to upgrade, QuillBot has a monthly cost of $19.95, but you can make savings if you purchase a semiannual or annual plan.

Is QuillBot Worth It?

QuillBot is a great tool for people who are looking to correct grammar and paraphrase text, for example, academics writing a dissertation or thesis. It includes features specifically built for academic purposes, such as a plagiarism detection tool and AI detector.

However, depending on what type of writer you are, it may not be the perfect tool for you needs. For example, if you are a creative writer, it can’t give genre-specific suggestions or developmental feedback on your stories—for which there are better tools out there.

QuillBot Review Summary

Overall, QuillBot is a great tool with plenty of useful features in the free version. Though QuillBot is most commonly known for its paraphrasing capabilities, the tool offers other features to assist your writing, including grammar checking, plagiarism checking, summarizing, and translation. 

You will need to upgrade to Premium to access customizable options and strengthen your writing further. For example, a copywriter will want to tweak the tool and set the writing type to Creative. Equally, a student will want to set the writer type to Academic.
