The quickest way is to check the "AI info" or "Made with AI" label that Meta automatically adds under the account name, and observe characteristic image errors such as distorted hands, incorrect handwriting, or excessively smooth skin. Additionally, you can pay attention to unnatural breathing in the voiceovers or captions that are too mechanically structured to distinguish them. However, nowadays, the line between "human-made" and "AI-made" is increasingly blurring as many photographers and creators use AI for post-processing (object removal, brightness adjustment). Instagram usually only labels images if AI played a key role in creating them. Therefore, it's becoming increasingly difficult to verify authenticity.
