Our Honest Paperpal AI Review: Pros, Cons & Real Results

There are plenty of things that can derail your academic life.

A failed thesis, a Sunday night you definitely shouldn’t have gone out for, and, nowadays, accidentally relying a little too much on AI as your writing buddy. But hey, no judgment here, we’ve all had our moments.

So you stumbled upon this new shiny tool that promises to make your research paper look polished and read like it was written by someone with their life together.

But with so many AI writing tools in 2025, everyone thinks their own is superior, with most of them just okay at best. 

Paperpal has positioned itself as the academic writer’s best friend.

The question is: does it actually deliver, or is it just another tool that’ll get your content flagged faster than you can say “academic integrity?”

• In our tests, Paperpal’s humanizer failed detection tests with GPTZero, showing obvious AI patterns.

• The tool offers solid grammar checking and paraphrasing for research papers, but falls short on AI detection evasion.

What Is Paperpal?

Paperpal is an AI-powered writing assistant designed for academics, researchers, and students who need to refine their scholarly work.

Think Grammarly, but with a PhD and a lot more citations.

The platform was built specifically for academic writing. That means it understands the difference between “et al.” and “etc.”

It knows that passive voice isn’t always the enemy in research papers. It gets that a formal word choice like “utilize” instead of “use” is expected in these settings.

Paperpal isn’t just one tool. It’s more like a Swiss Army knife for academic writing.

You’ve got grammar checking, виявлення плагіату, paraphrasing, and yes, even an AI humanizer tucked away somewhere in the depths of their feature set.

The company positions itself as the go-to solution for researchers who want to publish in international journals.

They claim to have helped improve millions of manuscripts. Big numbers, big promises. Let’s see if they hold up.

Key Features of Paperpal

Paperpal comes loaded with features that sound great on paper. No pun intended.

• Grammar and Language Enhancement: This is their bread and butter. The tool scans your academic writing and suggests improvements that align with formal academic style. It catches the obvious stuff, like comma splices and subject-verb agreement, but it also flags discipline-specific language issues.
• Перевірка плагіату: Accidentally plagiarizing is still plagiarizing, and nobody wants to read an email from the dean. Their checker compares your work against academic databases and published research.
• Асистент з написання текстів зі штучним інтелектом: Need help expanding an idea or restructuring a paragraph? Their AI can generate academic text based on your prompts. It’s trained on scholarly writing, so it won’t suggest you start your methodology section with “Once upon a time.”
• Інструмент перефразування: This tool rewrites sentences while preserving the original meaning. It’s useful when you’re citing sources and need to avoid direct quotes or when you’ve used the word “significant” seventeen times within a few paragraphs.
• Real-Time Editing: As you type, Paperpal offers suggestions. It’s like having a pedantic writing partner who never gets tired of pointing out your mistakes.

The interface is clean. The suggestions pop up without being intrusive. For basic academic writing tasks, it does what it says on the tin.

How to Use Paperpal

Getting started with Paperpal is straightforward. You sign up, paste your text, and watch the suggestions roll in.The перевірка на плагіат scans your document against their database.

It highlights potential matches and gives you a similarity score. Standard stuff, nothing revolutionary, but it works.

The AI writing assistant can generate content based on prompts. You tell it what you need, and it produces academic-sounding text.

The quality varies depending on how specific your prompt is and what field you’re writing in.

Their paraphrasing tool takes your existing sentences and rewrites them. You select the text, click paraphrase, and get alternatives.

Some are better than the original. Some are worse. Most are just different.

But here’s what we’re really here to talk about: Humanize AI by Paperpal.

This feature supposedly takes AI-generated text and makes it sound more human. The goal is to help your content bypass AI detectors while maintaining readability.

It’s the feature that matters most in 2025, during a time when everyone’s paranoid about AI detection.

Finding the tool on their website, though? That’s the first challenge. It’s not prominently featured. You won’t see it on their homepage.

You have to dig through their tools section like you’re searching for Atlantis. When you finally find it, you upload your AI text, click humanize, and hope for the best.

We tested it. The results were not great.

Test and Result: Paperpal AI

Time for the main event. We’re testing Paperpal’s Humanize AI feature using a methodology inspired by ZDNet’s widely referenced AI detection benchmark.

We took a chunk of ChatGPT-generated content about generative AI writing.

Pure AI, no human editing. We ran it through Paperpal’s Humanize AI tool, then we ran the humanized version through GPTZero, one of the most reliable AI detectors available.

GPTZero flagged the humanized content as 100% AI-generated. That’s basically a complete fail.

If you’re trying to make AI content appear human-written, getting a 100% AI score is like trying to disguise yourself with a fake mustache and having everyone immediately recognize you anyway.

If you’re using an AI humanizer, you need it to actually work. You need confidence that your content will pass scrutiny. Paperpal doesn’t deliver that confidence.

What does work? Our own AI Detector and Humanizer at Undetectable AI is specifically designed for this challenge. We’ve built tools that don’t just shuffle words around.

They fundamentally restructure AI patterns to genuinely appear human-written.

When you need to verify if your content truly appears human and rewrite any parts flagged as AI, you need tools that have proven success rates.

Advantages and Disadvantages of Paperpal AI

Переваги:

• Excellent grammar checking specifically tuned for academic writing
• Plagiarism checker integrates well with research workflows
• Interface is clean and doesn’t overwhelm you with features
• Real-time suggestions help you learn as you write
• Discipline-specific language recommendations show they understand scholarly writing

Недоліки:

• Free tier is basically useless, with only 50 words included
• Humanize AI feature is hidden and hard to find on their website
• AI humanization results are poor, failing most detection tests
• Pricing is steep for what you actually get
• The humanizer doesn’t show detection results despite claiming it will

What Paperpal does well is research writing and basic paraphrasing. That’s their wheelhouse. They understand academic conventions, citation styles, and the formal tone required for scholarly work.

What they don’t do well is Гуманізація ШІ. Their humanizer feels like an afterthought, a feature they added because everyone else was doing it.

It’s not integrated into their core offering. You have to hunt for it. And when you find it, it doesn’t work well enough to justify using it.

The biggest red flag? 

They claim their humanizer will provide detection results along with the humanized text. It doesn’t.

You get your rewritten content, but no actual feedback about whether it will pass AI detectors.

That’s like a GPS that tells you to turn left but won’t tell you if you’re going the right direction.

Paperpal AI vs Undetectable AI

We ran the same test with a different tool.

We took that same ChatGPT-generated content on climate change. This time, we ran it through Undetectable AI’s humanizer instead of Paperpal’s.

The difference was immediate. The text came back restructured at a deeper level. Sentence patterns changed. Vocabulary was more polished.

AI fingerprints were genuinely removed, not just masked.We tested the Undetectable AI version with GPTZero and got 99% confidence as human-written.

That’s not a small improvement over Paperpal’s 94% AI score. That’s a complete 180. That’s the difference between failing and passing, between getting caught and staying clear.

Why the difference?

It comes down to how the tools approach humanization. Paperpal makes surface-level changes, which are essentially advanced paraphrasing with some syntax adjustments.

Undetectable AI reconstructs the content on a structural level, eliminating the patterns that AI detectors look for.

For academic writing where detection matters, this difference is everything.

Instead of just making your text sound better, you get to ensure it reads genuinely human-authored.

Can Paperpal AI Detect AI-Edited or Paraphrased Text?

Коротка відповідь: Ні.

Long answer: Paperpal’s detection capabilities are limited for two key reasons.

First, their humanize tool isn’t explicitly showcased on their website. You’d think if they had a strong AI detection and humanization combo, they’d advertise it prominently.

They don’t. It’s buried in their feature list like a secret menu item at In-N-Out.

Second, despite claiming they’ll provide detection results alongside humanized content, they don’t actually deliver those results.

You get your rewritten text, but you’re left guessing whether it’ll pass AI detectors. That’s not useful, but incredibly frustrating.

Compare this to Undetectable AI’s approach. We show you detection scores before and after humanization.

You see exactly how AI detectors rate your content, then you see how our tools improve those scores. 

Transparency matters.

When it comes to supremacy in AI content transformation, there’s a clear hierarchy. Paperpal’s native paraphraser is okay for basic academic rewrites.

Their extended Humanize AI tool exists, but underperforms.

Тим часом, Непомітний перефразовувач ШІ і AI Stealth Writer are purpose-built to edit AI-generated content and reliably evade detection.

The difference shows up in testing. It shows up in real-world use. And it shows up in user confidence.

If you’re working with AI-generated content that needs to pass as human-written, you need tools that have proven track records.

You need to see the detection scores and results you can trust. Paperpal doesn’t consistently deliver that. Undetectable AI does.
