Undetectable AI vs. Sapling: Does It Pass?

For the past few years, AI detection tools have become increasingly common in academic and professional spaces — with some even going as far as to require them. While the intent of stopping AI misuse is admirable, a concerning trend has emerged: the rise of false positives in AI detection.

Let me give you a scenario.

Imagine pouring your heart into an essay or article, only to have some algorithm accuse you of cheating. What’s worse is that these false positives can lead to serious consequences, especially in academic settings where original work is required. And let me tell you, this is an emerging trend.

Since last year, I’ve started integrating Undetectable AI into my workflow and I’ve found it to be accurate. But what happens when you put it against one of the best AI detection tools in the market? Let’s find out together. In this article, I’ll be putting Undetectable AI to the test by testing its output against Sapling.

What are Undetectable AI and Sapling?

Have you ever spent all night writing something — maybe an essay, report, or anything in between — only for an AI detection tool to falsely detect it as machine-generated? That problem is what Undetectable AI addresses. It is a popular AI bypassing platform that rewrites your input so it wouldn’t be flagged falsely as AI. Here is our complete review of Undetectable AI.

While its most popular feature is its paraphraser, Undetectable AI offers more. If you’re worried about a professor asking for further proof but you weren’t able to document one, you can make use of their AI human typer extension to write an entire essay for you in Google Doc so it would show up in the document’s history. We’ve also reviewed it in the past, which you can view here.

Now, Sapling is much more straightforward. Think of it as the AI police. It’s designed to detect every possible instance of AI writing in an input, and it does its job at a high level. During our latest testing, we found Sapling to be one of the most effective AI detectors in the market — a solid feat considering that it’s completely free.

The biggest reason why it’s so effective is that it’s created by developers from Meta, Google, Stanford, and University of California – Berkeley. According to its changelogs, as of June 6th, they’ve also improved the model to be more accurate against GPT-4o, Gemini, Claude 3, and Llama 3.

How Does Undetectable AI Work?

So, let’s talk a bit about AI bypassers, specifically Undetectable AI. These tools have two main tricks to hide from AI detection.

First, they’re pretty clever about rearranging the text. They get rid of those telltale AI signs such as repetitive sentence structures, overly common AI words, and writing that lacks any real emotion.

The second trick? They actually add in human-like errors on purpose. We’re talking about the occasional typo, some grammar slip-ups, and misplaced punctuation here and there. While this might lower the AI detection score, it can also make your content a bit harder to read. It’s a trade-off, really.

Overall Tally

A Few Reminders

Like I said earlier, one of the ways Undetectable AI avoids AI detection is through adding intentional errors. This can only mean one thing:

Using Undetectable AI + any LLM is not a substitute for actual writing.

And the reason goes beyond the fact that Undetectable AI’s output is mostly unreadable. There’s also the fact that cheating through generative AI is a serious offense in academic institutions. Always remember that AI can’t replace your own learning and growth. Use it as a tool to enhance your understanding, and not as a shortcut.

All Said And Done

I’ve always maintained that Sapling is one of the best free AI detectors in the market. They’re also one of the few that keeps upgrading their back-end to better detect content from newer learning models.

So, what does it mean for Undetectable AI that it can successfully bypass a detector as good as Sapling?

Simple and straightforward — it’s extremely effective. It shows that Undetectable AI is a worthwhile investment, whether you’re a student or just someone who’s unfortunate enough to regularly get false positives. For a small price, you’d never have to worry about AI detectors ever again. That’s one load off your mind.

And if you’re not satisfied with this, we’ve also tested Undetectable AI against Originality and Content at Scale previously. Give them a read and good luck!
