Galaxy.ai is an online AI combination tool that includes everything from an AI image generator to talking photos, AI prompts, chat and more.
As part of its collection of tools, it also includes a free AI essay humanizer (for up to 500 words).
We decided to see how well its AI humanizer worked with a sample of text generated by ChatGPT 5 and then whether it was still detectable when run through leading AI detectors, including Originality.ai, Writer, and ZeroGPT.

Galaxy AI is a combination of AI tools, including chat, image generators, video generators and more.
We decided to see how well its AI humanizer could rewrite text generated by ChatGPT and whether the new humanized text would pass detection with Originality.ai and two other modern AI detectors.

Many students, professionals, and content creators alike use AI image generation, video generation and other tools to help them create content faster.
AI humanizers are a part of the collection of tools that are often built to attempt to bypass AI detectors by making text generated by ChatGPT and other LLMs (Google Gemini, Jasper, Claude, etc.) sound more human.
They do this in a variety of methods, from simple synonym substitution to changing the cadence and tone of the writing. Galaxy AI humanizer is one such tool.
The Galaxy AI humanizer is free to use; however, it requires you to register in order to use it. Note: The site doesn’t tell you this until after you’ve pasted in text, so you may want to pre-emptively register in order to avoid having to go back and paste your text again.
It accepts text up to 500 words, and the humanized text appears below your original text (see the screenshot below).
The test was designed to see if three popular AI detectors, including the Originality.ai AI content detector, Writer, and ZeroGPT, could detect both AI-generated text and humanized text written by the Galaxy AI Humanizer.
Step 1: First, we generated a paragraph of text on a random topic in ChatGPT. This was done to make sure that all tools would have a baseline of AI-generated text to identify, along with humanized text.
Step 2: We then ran the AI-generated text through Originality.ai, ZeroGPT, and Writer AI to get a base score.
Step 3: We pasted the same AI-generated text into the Galaxy AI Humanizer and had the platform “rewrite” it. In this case, the Galaxy AI Humanizer created two humanized outputs (see the screenshot above), so in step 4, we used the second humanized output.
Step 4: We then pasted the humanized AI text into ZeroGPT, Writer AI, and Originality.ai to see if they could successfully detect the humanized version of the text as having been AI-generated or not.
Original content (AI-generated): 100% Confidence that the text is Likely AI
Galaxy AI Essay Humanizer Version: 100% Confidence that the text is Likely AI
Original content (AI-generated): 89% Human-generated (11% AI-generated)
Galaxy AI Essay Humanizer Version: 90% Human-generated (10% AI-generated)
Original content (AI-generated): 98% AI-generated
Galaxy AI Essay Humanizer Version: 100% AI-Generated
Based on our head-to-head tests, only Originality.ai was able to definitively rule both the ChatGPT-generated text and the Galaxy.ai humanized text as AI with 100% confidence.
ZeroGPT came in at a close second with high marks (98% detection of the ChatGPT text and 100% of the humanized text). Writer’s AI detector did not detect either the original AI-generated or the humanized version.

You can use Galaxy AI humanizer for nearly any type of text (up to 500 words) for free, including blog posts and essays. However, in using it for essays, such as university assignments, you run the risk of having your work labelled as AI, which can have serious consequences. Always review assignment, course, and institution guidelines before incorporating AI tools in your writing process.
Alternatively, avoid using AI and instead use your own experience and knowledge to infuse your work with your original thoughts and ideas — something that AI can’t replicate.
As you can see from our tests, the Galaxy AI Essay humanizer was unable to make AI text undetectable by modern AI detectors like Originality.ai.
