The paraphrasing tool is the star feature. It changes your words while keeping the same meaning.

But QuillBot does more than just paraphrasing. It also checks grammar, summarizes long texts, and even creates citations for your school project or research paper.

Unlike basic grammar checkers, QuillBot helps you rewrite complex sentences into simple, clear ones.

Best QuillBot Features

Let’s look at the standout QuillBot features that make this herramienta de IA worth your attention.

1. Parafrasear

This is the best paraphrasing tool I’ve used.

You paste your text. QuillBot rewrites it while keeping the original meaning.

The paraphraser tool offers seven keyboard modes: standard, fluency, formal mode, simple, creative mode, expand mode, and shorten mode.

Each writing mode changes how your text sounds. Creative mode adds a personal touch to your writing. Write in shorten mode to cut your essay’s word count fast. You can compare paraphrases, write different versions, and pick the best one.

Not gonna lie, I was skeptical at first. But the results surprised me. It handles complex sentences way better than I expected.

2. Corrector gramatical

QuillBot’s grammar checker catches mistakes that regular spell checkers miss.

It doesn’t just flag errors. It explains why something is wrong. This helps you learn while checking grammar.

I ran it on a 2,000-word blog post. It found 14 errors that MS Word completely missed.

The grammar checking works in real-time. You see suggestions as you type.

For professional communication, this tool is a game-saver. It catches tone issues and awkward phrasing too.

3. Resumidor

Got a 5,000-word article you need to understand fast?

QuillBot’s summarizer pulls out the key points in seconds.

You pick how long you want the summary. It works great for research papers, news articles, and long reports.

I used it to summarize 12 research papers for a client project. It saved me about 4 hours of reading time.

The tool gives you details about what matters most. Perfect for students with heavy reading loads.

Here’s a quick walkthrough of how QuillBot works in practice.

4. Translator

QuillBot supports translation for over 45 languages.

This includes French, Spanish, German, Chinese, and many more.

The translations feel natural. Not like a robot wrote them.

I tested it with a French text message from a client. The translation was accurate and kept the right tone.

If you write in multiple languages, this feature alone makes QuillBot worth trying.

5. QuillBot Keyboard

El QuillBot keyboard brings the AI writing keyboard right to your phone.

It works as your regular keyboard. But with text and emoji prediction powered by AI.

QuillBot’s mobile keyboard lets you paraphrase any text message, email, or redes sociales correo.

The features QuillBot keyboard offers include grammar checking, quick paraphrasing, and prediction settings you can customize.

Here’s what nobody tells you: the keyboard modes are a hidden gem. You can switch between formal and casual writing with one tap.

Introducing in-app subscriptions means you can upgrade right from the keyboard app. The app also supports dark themes for comfortable night-time writing.

A note on app privacy and data safety: QuillBot updated its privacy policy in late 2025. Desktop users should know that text inputs may be stored. Check the latest app privacy details before using it with sensitive content.

6. Detector de plagio

QuillBot’s plagiarism checker scans your writing against billions of web pages.

It highlights any parts that match other sources. You see exactly what needs to change.

The premium version gives you 25,000 words per month of plagiarism scanning.

For academic integrity, this is huge. It helps ensure the originalidad de tu trabajo.

I tested it with a 3,000-word article. It found two sections that were too close to existing content. Fixed in minutes.

Watch how I set up the plagiarism checker in under 2 minutes.

7. Free Citation Generator

Need to create citations for a research paper? QuillBot makes it easy.

Just paste the URL or book title. QuillBot builds the citation for you.

It supports APA, MLA, Chicago, and other major styles. The citation generador helps you maintain academic integrity by giving proper credit.

I used it for a school project and it saved 30 minutes of formatting work.

8. QuillBot’s AI Chat

This is a newer feature. QuillBot’s AI chat lets you ask writing questions directly.

Necesitar ayuda reunión creativa ideas? Ask the AI. Want to outline an essay? It helps with that too.

QuillBot Flow is the centralized workspace that pulls research, paraphrasing, and citations into one place.

The writing experience feels smooth. It’s like having a writing assistant that never sleeps.

For content creation tasks, this AI tool speeds up your workflow a lot.

9. AI Humanizer

Got AI generated content that sounds robotic? The humanizer fixes that.

It rewrites AI text to sound more natural and human.

QuillBot makes the output feel like a real person wrote it. But I need to be honest here.

In my testing, it reduced AI detection scores by about 40-60%. It’s not perfect. AI detectores can still flag some content.

It works best for improving tone and readability. Don’t rely on it to completely bypass AI detection systems.

See the difference the humanizer makes in real-time.

QuillBot Pricing

Users report that the free version of QuillBot is great for basic tasks. But the premium version unlocks features that make a real difference.

You might overpay if: You only need basic spelling and grammar help. The free version might be enough.

Cronología: 90 days of daily use with the premium plan.

Resultados:

Would I use it again? Yes. QuillBot is my go-to for paraphrasing. For pure grammar checking, I still open Grammarly sometimes. But QuillBot handles most of my editing work now.

QuillBot helps writers at every level. It’s not perfect. But it makes the writing process faster and smoother.
