JAKARTA - Japanese artificial intelligence startup Valar Intelligence has developed Puddin AI, a system that helps campuses distinguish between students' own writing and AI-generated text.

As reported by Kyodo News, quoted Sunday, June 14, Puddin AI analyzes the process of writing academic papers. Users must write and submit the manuscript directly through the platform.

The way it works is not just reading the final result. Puddin AI notes when the user starts writing, how fast he types, and how the sequence of his revisions.

When the identification button is pressed, the system assesses the level of "humanity" of the writing with about 200 indicators. The indicators include spelling errors that humans commonly make, pauses when writing, and an estimate of the normal time to complete the manuscript.

If a user copies and pastes AI-generated text, the writing process becomes very short. From that pattern, the system can assess whether the writing is human-made or not.

The results of the examination are divided into three categories, namely AI, AI-assisted, and humans. According to the developer, Puddin AI can handle Japanese, English, and four other languages. This system can also be used for university tasks, academic papers, and company documents.

Kyushu University has tried Puddin AI in lectures. Several dozen other universities are also considering using the system, according to the company.

Andrew John Chapman, associate professor of energy economics at Kyushu University, said the system could help maintain the authenticity of students' work.

"I want students to take the time and write their own work. This system can verify authenticity, so that fair assessment becomes possible," Chapman said, as quoted by Kyodo News.
