QuillBot vs. Grammarly: Interface

QuillBot and Grammarly are online AI writing tools, but how user-friendly are their user interfaces?

screenshot of the quillbot dual pane interface

QuillBot is an AI site for writing that offers a clean dual-pane interface. The left pane is where you can paste your original text, and the left pane will display the paraphrased text.

Different paraphrasing modes are arranged horizontally above the panes. Next to the paraphrasing modes is a slider to control the extent of synonyms you want to use.

Left navigation provides quick access to all tools that the QuillBot suite offers. On the top right, you can select the English locale (the default is American English).

The user interface is excellent, with well-thought-out and intuitive navigation.

Grammarly, too, has a clean interface with an online editor where you can write directly, upload a document, or copy & paste your content.

The editor is on the left. On the right is a small panel where the program will display writing suggestions such as spelling errors, grammar mistakes, etc.

Grammarly categorizes all mistakes and highlights each category with different colors. The text you add to the editor will also highlight errors with category colors.

This handy writing tool checks for mistakes in real-time. If there are uncommon words, you can quickly add them to your dictionary, too.

Overall, this AI-powered writing tool has a brilliant UI.

Winner: Tie because QuillBot and Grammarly offer clean and intuitive user interfaces.

QuillBot vs. Grammarly: Paraphraser

Both QuillBot and Grammarly have paraphrasing tools, but which one is better?

screenshot of quillbot standard paraphraser page

QuillBot is primarily a paraphrasing tool with many features to control output quality. You can start by selecting the language locale, that is, between American, Australian, British, or Canadian English.

The split panel is where you can paraphrase your content. The left pane accepts the input, whereas the right panel provides the output. By default, the tool uses the Standard mode to rewrite the content without altering the tone.

However, you can always change the mode and switch between 5 modes – Standard, Fluency, Formal, Simple, and Creative. The Expand and Shorten features use machine learning to expand or shorten your input.

But remember, QuillBot will allow only three writing modes in the free version.

The tool also has a word-freezing feature that allows selecting words you don’t want to be replaced by synonyms. The free version allows freezing only one word.

QuillBot also offers a synonym limiter. There is a slider on the top that you can drag to decide the extent of synonyms to use while rewriting. Remember! The fewer synonyms, the greater the accuracy.

Finally, an integrated Thesaurus allows clicking on a word or phrase in the output pane to select better synonyms.


Grammarly also has a paraphrasing feature but will not allow rewriting an entire input. It won’t paraphrase anything until it spots a complex sentence that it can simplify.

When Grammarly spots a complex or grammatically incorrect sentence, it will show a paraphrased version. So, you have no control.

Winner: QuillBot because its paraphrasing tool is way more powerful and advanced.

QuillBot vs. Grammarly: Grammar Checker

Both have grammar checkers, but which program is better at checking grammar?

screenshot of quillbot in-article grammar checker

QuillBot’s grammar checker is a free tool that allows unlimited grammar checks. The feature currently supports English and German.

The grammar checker has an editor where you can write or paste your text. It uses AI to check grammar in real-time and highlight errors.

The tool checks for grammar, spelling, and punctuation errors and highlights them all. You can click on the highlighted items to see suggestions.

Also, the grammar checker integrates the paraphrasing tool that you can use for completely rewriting sentences.

Grammarly’s grammar checker is far more powerful. It can check grammar for all types of writing, such as AI for blog posts, academic papers, etc.

Not only will Grammarly identify basic grammatical mistakes using artificial intelligence, but it will also provide advanced suggestions like identifying repetitive words, tone, passive voice misuse, etc.

The premium plans of Grammarly are the only ones that offer its advanced features. The free version includes only the basic grammar checker.

Grammarly free will offer only basic writing suggestions, which include basic grammar and spelling errors. You’ll need the premium version of Grammarly for help with punctuation, style, sentence rewriting, and other advanced English grammar issues.

Winner: Grammarly because it catches more subtle errors than QuillBot.

QuillBot vs. Grammarly: Plagiarism Checker

Plagiarism-checking tools are available with both QuillBot and Grammarly, but which one is a better choice?

The QuillBot plagiarism checker is relatively new. It is best suited for checking academic papers. However, the bad thing is that the plagiarism tool allows checking up to 20 pages per month for its premium version. Free users cannot use the tool.

This limitation can be stifling for students and academics. The good news is that QuillBot permits purchasing extra pages if necessary.

People have more faith in Grammarly’s plagiarism checker because it has been around for so long. It is suitable for checking all types of content.

Unlike QuillBot, Grammarly doesn’t limit the number of pages you check with its plagiarism checker. This makes the tool a cost-effective alternative.

Winner: Grammarly because it doesn’t put a limit on monthly plagiarism checks.
