Grammarly vs QuillBot for Writers: Which Tool Should You Use?

Writing tools have changed how we edit and improve our work.

Two names appear often in this space.

Grammarly and QuillBot.

Both can improve written content. Both now include AI-powered features. Both offer grammar checking and rewriting tools.

Yet they approach writing differently.

Grammarly focuses heavily on editing, clarity, tone, and writing assistance. QuillBot began with paraphrasing and has expanded into a broader writing toolkit.

So, which one should writers use?

The answer depends on what you need help with.

If you want to polish your writing, one may fit better. If you regularly rewrite existing text, the other may fit better.

And sometimes, using both makes sense.

Let’s look at how they compare.

Grammarly vs QuillBot: The Main Difference

The easiest way to understand these tools is to look at their original strengths.

Grammarly is primarily an editing and writing assistant.

It checks grammar, spelling, punctuation, clarity, and tone. It also offers rewriting and generative AI features.

QuillBot is strongly focused on rewriting and paraphrasing.

Its toolkit includes paraphrasing, grammar checking, summarizing, translation, AI detection, and other writing features.

That difference matters.

Imagine you have just finished a blog post.

Your sentences are mostly correct. However, some sound awkward.

Grammarly can help you polish those sentences.

Now imagine you have a sentence that feels repetitive.

You want five different ways to express it.

That’s where QuillBot’s paraphrasing approach becomes useful.

So the real question isn’t simply:

“Which tool is better?”

A better question is:

“Which tool fits this part of my writing process?”

What Grammarly Does Best

Grammarly has traditionally focused on helping people write better sentences.

Its writing assistant provides real-time feedback.

It can identify issues with grammar and punctuation. It can also suggest improvements for clarity and tone.

This makes Grammarly useful during the editing stage.

Imagine writing an email.

You finish the first draft.

Grammarly can help identify problems before you send it.

The same applies to:

• Blog posts
• Website copy
• Emails
• Reports
• Social media posts
• Business documents
• Academic writing

Grammarly has also expanded beyond traditional grammar checking.

Its current AI writing assistant includes generative features. The free plan currently includes 100 AI prompts per month. Pro includes 2,000 prompts per month.

That means Grammarly is no longer just a spelling checker.

It has become a broader writing assistant.

What QuillBot Does Best

QuillBot’s identity is closely connected with paraphrasing.

Its Paraphraser lets users rewrite existing text in different ways.

The current Premium version includes multiple paraphrasing modes. Free users get more limited access.

This can help when a sentence feels:

• Too repetitive
• Too complicated
• Too informal
• Too wordy
• Difficult to understand

QuillBot also offers more than paraphrasing.

Its current tools include a grammar checker, summarizer, translator, citation generator, AI detector, AI writing features, and other tools.

Its Android app also includes a floating writing assistant and keyboard support.

So QuillBot has developed into a much broader writing platform.

Grammar Checking: Grammarly vs QuillBot

Both tools can check grammar.

However, grammar checking isn’t the only thing you should consider.

QuillBot’s free Grammar Checker can identify grammar, spelling, and punctuation errors. Premium adds more advanced recommendations. These include passive-voice fixes and suggestions for clarity and conciseness.

Grammarly also provides real-time writing feedback.

Its current writing assistant focuses on grammar, clarity, tone, and related improvements.

For a writer, the important difference is workflow.

Do you want an assistant watching your writing while you work?

Or do you often have completed passages that need rewriting?

Your answer can help determine which tool makes more sense.

Paraphrasing and Rewriting

This is where the comparison becomes more interesting.

QuillBot built much of its reputation around paraphrasing.

Its Premium Paraphraser currently offers nine modes. It also provides custom modes and a synonym slider.

That gives writers more control over rewritten text.

Grammarly also provides sentence rewriting.

Its AI writing assistant can help users rewrite and improve existing content.

But the purpose can feel different.

Think about these two situations.

Situation 1

You wrote:

The introduction of the article is not very clear.

You want the sentence polished.

A writing assistant such as Grammarly can help.

Situation 2

You want several alternative ways to express the same idea.

You want to change the structure.

You want a more formal or creative version.

A paraphrasing-focused tool such as QuillBot can be useful here.

That’s why writers should not treat paraphrasing and editing as identical tasks.

They aren’t.

Tone and Writing Style

Good writing isn’t only about correct grammar.

Your tone matters too.

A business email needs a different voice from a personal essay.

A product description needs a different tone from a short story.

Grammarly provides tone-related writing assistance. Its current product also supports rewriting and communication improvements.

QuillBot also provides tone and style-related capabilities through its writing tools. Its Premium Grammar Checker includes Tone Insights and advanced writing recommendations.

For writers, this creates an important reminder.

Don’t let the tool decide your voice.

Use suggestions as options.

Then make the final decision yourself.

That matters especially for creative writing.

Which Tool Is Better for Bloggers?

Bloggers have different needs from students or casual users.

A blogger might need to:

1. Research a topic.
2. Create an outline.
3. Write a first draft.
4. Improve sentences.
5. Check grammar.
6. Adjust the tone.
7. Rewrite repetitive sections.
8. Edit the final article.

Neither tool should replace the entire process.

That’s especially important when writing articles for search.

A useful article needs original ideas and meaningful information. Google says helpful content should provide substantial value rather than simply rewriting existing sources.

This is where writing tools should support your workflow.

They shouldn’t become your workflow.

For example, you could draft an article yourself.

Then use Grammarly to identify language problems.

You could use QuillBot when a particular paragraph needs restructuring.

Then you review everything yourself.

That approach keeps the writer involved.

Which Tool Is Better for Creative Writers?

Creative writing creates a different challenge.

A creative writer may intentionally break grammar rules.

They may use fragments.

They may repeat a word for effect.

They may create unusual sentence structures.

A writing assistant may not understand the artistic reason behind every choice.

That’s why creative writers should treat automated suggestions carefully.

A grammatically unusual sentence isn’t automatically a bad sentence.

Sometimes the unusual sentence is exactly what gives the writing character.

For creative work, the writer remains the final editor.

The software should provide suggestions.

It shouldn’t become the author.

This is also why writing craft matters beyond software. Our article on Bird by Bird by Anne Lamott: What This Book Really Teaches About Writing explores the human side of writing.

Can You Use Grammarly and QuillBot Together?

Yes.

And this may actually make more sense than choosing only one.

Think about a typical writing workflow.

Step 1: Write your first draft

Don’t worry about every sentence.

Get your ideas down first.

Step 2: Edit your draft

Use Grammarly to identify grammar and clarity problems.

Step 3: Find repetitive sentences

Look for sections that feel too similar.

Step 4: Rewrite selected sentences

Use QuillBot when you need alternative phrasing.

Step 5: Read everything yourself

This step matters most.

Don’t accept every suggestion automatically.

Step 6: Restore your voice

Some automated suggestions may sound unnatural.

Change them.

Your finished article should still sound like you.

This workflow also connects with our discussion of Grammarly vs Human Editing: Can a Writing Tool Really Replace an Editor?.

Grammarly vs QuillBot Pricing

Pricing changes regularly.

So you should check the official pages before purchasing.

As of 2026, QuillBot lists Premium at $8.33 per month when billed annually. Its monthly plan is listed at $19.95.

Grammarly currently offers Free and Pro plans, along with business-focused options. Its AI writing assistant provides 100 monthly prompts on Free and 2,000 on Pro.

The actual value depends on your workflow.

Paying for more features doesn’t automatically make a tool more useful.

You may only need one specific feature.

That’s why testing the free versions can make sense before subscribing.

Which One Should You Use?

There isn’t one answer for every writer.

Your writing habits matter more than a feature count.

Choose Grammarly if you mainly want to:

• Check grammar.
• Improve clarity.
• Refine tone.
• Polish professional writing.
• Get writing suggestions while you work.
• Rewrite individual sentences.

Choose QuillBot if you mainly want to:

• Paraphrase existing text.
• Experiment with different wording.
• Restructure sentences.
• Summarize content.
• Work with multiple rewriting modes.
• Use a broader collection of writing tools.

Consider using both if you:

• Write frequently.
• Edit long articles.
• Rewrite sentences often.
• Work with different types of content.
• Want separate tools for editing and paraphrasing.

The better choice depends on the problem you’re trying to solve.

Don’t Let Writing Tools Flatten Your Voice

There is one mistake writers should avoid.

Accepting every suggestion.

Writing software doesn’t know your entire intention.

It sees words.

You see the story behind those words.

You know your audience.

You know your personality.

You know what you want the reader to feel.

A tool can identify a grammatical problem.

It can suggest another sentence.

It can offer a different tone.

But you still need to decide whether the change improves the writing.

This is particularly important for personal essays, creative writing, opinion pieces, and storytelling.

Good writing isn’t simply error-free writing.

It’s writing that communicates something clearly and meaningfully.

What About Blog Traffic?

A writing tool can improve your sentences.

It cannot guarantee readers.

A polished article can still receive little traffic.

That’s because writing quality represents only one part of successful blogging.

Topic selection, search intent, structure, internal linking, discoverability, and reader value also matter.

We’ve explored this problem in Why Your Blog Posts Aren’t Getting Traffic Even When They’re Good.

The important lesson is simple:

Better writing helps.

But better writing alone isn’t the entire blogging strategy.

Final Thoughts

Grammarly and QuillBot are no longer simple grammar tools.

Both have expanded into larger AI-powered writing platforms.

Yet their strengths remain different.

Grammarly is strongly positioned around editing, clarity, tone, and writing assistance. QuillBot places greater emphasis on paraphrasing while offering a wider collection of writing tools.

For many writers, the choice isn’t about finding a universal winner.

It’s about finding the right tool for the task.

Use software to improve your writing.

Don’t use it to replace your judgment.

And most importantly, don’t let a writing tool erase your voice.

That is still the part only you can provide.
