Grammarly vs QuillBot: Feature-by-Feature Comparison
Now that we understand what each tool does, let’s compare them in detail to see which one performs better in different areas.
Grammar Checking Accuracy
Grammar correction is where Grammarly truly excels.
Grammarly’s AI engine has been trained on billions of pieces of writing data, allowing it to detect grammar mistakes with extremely high accuracy.
It can identify problems such as:
- incorrect verb tense
- subject-verb agreement errors
- misplaced punctuation
- sentence fragments
- passive voice usage
- wordiness
For example:
Incorrect sentence:
The students was preparing their assignment yesterday.
Grammarly correction:
The students were preparing their assignment yesterday.
Grammarly also explains why the correction is necessary, which helps students learn and improve their writing skills over time.
QuillBot does include a grammar checker, but it is more basic compared to Grammarly.
Its grammar suggestions are generally focused on simple corrections rather than deep writing analysis.
For students who want the most accurate grammar assistance, Grammarly clearly wins in this category.
Winner → Grammarly
Paraphrasing Power
When it comes to paraphrasing, QuillBot is one of the best tools available.
Its AI rewriting engine can transform sentences while maintaining their original meaning.
Students often use QuillBot when they need to:
- rewrite assignments

QuillBot’s different writing modes allow users to control how the sentence is rewritten.
For example, Academic Mode is especially useful for students writing research papers or formal essays.

Because of this, QuillBot is clearly the better tool for rewriting sentences.
Winner → QuillBot
AI Writing Assistance
Both Grammarly and QuillBot now offer AI writing assistance, but their approaches are slightly different.
Grammarly’s AI assistant focuses on helping users improve writing quality. It can suggest ways to rewrite sentences, improve tone, and enhance clarity.
It can also help with tasks like:
- drafting emails

- improving sentence structure
QuillBot’s AI capabilities are more focused on rewriting and summarizing existing text rather than generating new ideas.
Because of its broader capabilities, Grammarly provides a more complete AI writing assistant.
Winner → Grammarly
Plagiarism Detection
Plagiarism detection is extremely important for students submitting academic assignments.
Grammarly includes a powerful plagiarism checker that scans billions of web pages and academic databases.
It highlights any text that matches existing sources and provides links to those sources.
This helps students ensure that their work is original before submitting it.
QuillBot also offers a plagiarism checker, but its database is smaller and its scanning capability is not as extensive.
For academic integrity, Grammarly is the safer choice.
