Wichtigste Erkenntnisse

• Originality AI detects raw ChatGPT (GPT-4o) reliably. We ran five ChatGPT outputs through the detector, and it identified all five as 100% AI-generated.

• Originality AI can still flag lightly edited and humanized text. It identified a manually rewritten ChatGPT sample and a sample edited through Undetectable AI’s basic humanizer as 100% AI-generated. 

• The detector only failed to detect AI-generated content when we humanized a sample through Undetectable AI’s most advanced humanizer. 

• Rarely does Originality AI flag human-written text as AI-generated. However, its confidence score lowers with writing styles that are clean, dry, and formal. 

• If you use ChatGPT for submissions that go through Originality AI reviews, your best safeguard is to run your generated outputs through Undetectable AI with the green toggle ON before publishing.

Does Originality AI Detect ChatGPT? The Short Answer

Yes, Originality AI is effective at detecting raw ChatGPT outputs. In our test below, it detected 100% of the GPT-4o-generated samples, including those that were lightly edited and humanized. It only failed to detect AI in the sample that was rewritten through Undetectable AI’s most powerful AI humanizer. 

What Originality AI Claims to Detect

According to its product page, Originality AI can detect GPT-3.5, GPT-4, GPT-4o, Claude, Gemini, and paraphrased AI text with over 99% accuracy. Our test focuses on GPT-4o, which is the model most people use in 2026. 

Originality AI vs Other Detectors

Originality AIcompetes with GPTZero, Copyleaks, ZeroGPT, and Turnitin’s AI detection layer.

Third-party benchmarks consistently rank it among the top two or three on raw AI text — which is why it’s the detector most publishers, agencies, and academic reviewers use. We’re focused on Originality AI specifically because it’s the tool most likely to be run against your content.

We Tested 13 Samples in Originality AI — Here’s What Came Back

To test the effectiveness and consistency of Originality AI’s text detectors, we conducted a simple experiment.

We used the detector on 14 total samples, including five unmodified ChatGPT outputs, five excerpts from verifiably human-written pieces, one human-edited ChatGPT sample, one sample edited through Undetectable AI’s basic AI Humanizer, and one sample edited through Undetectable.AI’s most advanced humanizer. 

Test 1: 5 Raw ChatGPT Samples

	Topic	Kategorie	Wortzahl	AI Score %	Urteil
Beispiel 1	The Difference Between Yin and Vinyasa Yoga	Health	145	100% AI	AI
Beispiel 2	What Is a Blockchain?	Technologie	159	100% AI	AI
Beispiel 3	What Is FAFO Parenting?	Lifestyle	147	100% AI	AI
Sample 4	What Is a REIT?	Finanzen	285	100% AI	AI
Sample 5	Who Organizes the Golden Globes?	General Knowledge	147	100% AI	AI

First, we generated five ChatGPT outputs across the categories of health, technology, lifestyle, finance, and general knowledge, each about 100 to 300 words long. We ran these samples through Originality AI to see how effectively it could detect AI content.

As predicted, Originality AI flagged all five samples as AI-generated. It was 100% confident in all results.

Test 2: Edited ChatGPT Samples

	AI Score %	Urteil
Unmodified Sample	100% AI	AI
Lightly Edited Sample	100% AI	AI
Humanized: Basic	100% AI	AI
Humanized: Undetectable	100% Original	Original

To test how effectively Originality AI could detect edited outputs, we selected one of the samples above and modified it in three different ways:

• First, we manually edited the text to sound more human. 
• Next, we ran the text through Undetectable AI’s basic humanizer.
• Finally, we ran the text through Undetectable AI’s advanced (Undetectable) humanizer.

Originality AI flagged the human-edited sample and the sample humanized through the basic detector as AI-generated. It had a 100% confidence score for both samples.

The result only changed when we used the sample that was edited using Undetectable AI’s advanced humanizer. This final sample bypassed Originality AI’s detectors and read as 100% original. 

Test 3: 5 Verifiably Human Samples

Titel	Autor	Beschreibung	Jahr	AI Score %	Urteil
Nixon Resigns	John Herbers	The news article on Nixon’s resignation.	1974	100% Original	Original
I Know What You Think of Me	Tim Kreider	A personal essay on the contrast between self-perception and external perception.	2013	100% Original	Original
Entrepreneur Habits for Better Financial Health	Unknown	An informative article on improving financial health as an entrepreneur.	2021	76% Original	Original
How to Start DMing	Reddit User	A Reddit guide on taking the Dungeon Master role in the fifth edition of Dungeons and Dragons.	2018	100% Original	Original
North Review	Roger Ebert	Acclaimed film critic Roger Ebert’s review of the 1994 film North.	1994	100% Original	Original

Finally, we fed Originality AI five verifiably human writing samples to test the prevalence of false positives. We made sure to cover a diverse spread of sources, including the kind of writing ChatGPT trained on: forum posts and straightforward informative internet articles. 

Originality AI identified all samples as human-written. However, its confidence in its results decreased when we submitted a sample written in a style similar to ChatGPT’s typical output.

This suggests that human-written content that is too dry or unexpressive can still read as AI-generated, though the risk is relatively low. 

What This Means for Anyone Using ChatGPT for Real Work

Raw ChatGPT Is a Liability If Detection Matters

If the authority evaluating your work uses Originality AI to detect AI-generated content, submitting unmodified ChatGPT output is a very risky move. As our test proved, the tool is very reliable at flagging unmodified GPT-4o content.

If writing the work yourself is not an option, it helps to run generated outputs through AI humanizers like Undetectable AI. 

Even Human-Edited Samples Can Be Flagged

Our test showed that Originality AI still flags human-edited ChatGPT outputs as completely AI-generated. It is powerful enough to recognize when AI is the backbone of a piece.

To efficiently bypass detection, it is more effective to run your work through an advanced humanizer.

Humanizing with Undetectable AI Helps Content Bypass Detection — But Only With the Green Toggle ON

Activating the green Undetectable toggle was the only way to bypass Originality AI’s detector. This setting applies the humanizer’s most advanced rewrite, which is designed specifically to evade modern AI detectors.

Less advanced humanizers may bypass weaker detectors, but detectors as sophisticated as Originality AI requires a stronger rewrite.

How to Make ChatGPT Content Undetectable by Originality AI in 4 Steps

If you use ChatGPT to write more efficiently but need to submit your work to an organization that uses Originality AI, you can run your draft through Undetectable AI’s humanizer to improve your chances of bypassing detection. Here’s how.

Generate Your Draft 

The obvious first step is to write a prompt into ChatGPT. Ask a question, or instruct the model to generate a specific number of paragraphs, sentences, or bullet points on your chosen topic. 

While it can be tempting to include style preferences such as context, tone, and reading level, hyper-specific prompting isn’t necessary. The AI humanizer will revise most of these stylistic details anyway. 

Humanize the Output Through Undetectable AI (With the Green Toggle On)

Upon generating the text, paste the output into Undetectable AI’s input box. Then, switch on the green toggle labeled ‘Undetectable.’ This unlocks the strongest human-mode rewrite, which will increase the text’s likelihood of bypassing AI detectors like Originality AI, 

Make Necessary Edits

While Undetectable AI is great at humanizing content, its primary goal is bypassing AI detectors, not getting your point across in the specific way that you want. Feel free to make necessary revisions if it helps the humanized output align better with your goals. 

Run the Output Through Originality AI

Finally, run the humanized text through Originality AI. More likely than not, it will confirm that your content reads as human.
