Nano Banana Pro prompted by THE DECODER

Pangram has released version 3.0 of its AI text detector. The most important new feature: the tool now classifies text into four categories instead of making a simple binary distinction between human and machine.

The new categories are: fully human-written, slightly AI-assisted, moderately AI-assisted, and fully AI-generated. For longer documents, Pangram 3.0 analyzes individual segments separately, a feature designed to spot cases where a human writes the first half of a text and an AI finishes the rest.
