How AI Models Work

An AI detector may give a passage a score of 80 percent, 20 percent, or “likely AI-generated.” That result can sound scientific, but it is still an estimate based on patterns in the finished text—not direct proof of who wrote it.

An AI explanation can be clear, patient, well organized, and completely convincing. Those qualities make it useful for learning, but they do not prove that the explanation is correct.

A search engine and an AI tutor can both answer a question, but they do not produce that answer in the same way. One mainly finds existing material. The other can build a new response around the conversation taking place right now.
