Want to find out if the text you’re reading online was written by an real human or spat out by a large language model (LLM) trying to sound like one? Mozilla’s Fakespot Deepfake Detector Firefox add-on may can help give you an indication. Similar to online AI detector tools, the add-on can analyse text (of 32 words or more) to identify patterns, traits, and tells common in AI generated or manipulated text. It uses Mozilla’s proprietary ApolloDFT engine and a set of open-source detection models.
