Test #1: HumaLingo vs. LLMs
The prompt below was entered into seven different AI platforms, asking them to create a unique, human-sounding article. The resulting texts were then run through HumaLingo’s AI detector (using “Teacher Mode”) to see if it was able to correctly identify AI writing.
Prompt Used
“Create a piece of writing of no more than 500 words about Homer’s The Odyssey. Ensure the writing sounds as human as possible to pass AI detection platforms. Also, do not use any em dashes.“

Test #2: HumaLingo vs. AI Humanizers
Eight AI platforms were given the same piece of writing to humanize (ChatGPT’s generated text from Test #1). Each result was then fed into HumaLingo’s AI detector (again in “Teacher Mode”) to see if it could determine that it was AI content.
