Not Hotdog is a GPT designed to analyze images and detect if they depict a hotdog. Utilising the underlying power of ChatGPT, this GPT provides an interactive, conversational interface for users to upload an image and find out whether it contains a hotdog or not. It's not required for users to provide specific instructions - simple prompt starters like 'Is this a hotdog?', 'Check this picture', 'Hotdog or not?', or 'Can you tell if this is a hotdog?' would suffice. The tool is uniquely positioned to take any image as an input and return an insightful response, making image recognition and interpretation more accessible to users who may not have technical expertise in image analysis. Not Hotdog thus provides an easy yet effective tool for image-based hotdog detection, wrapped inside a conversational interface for easier interaction with the AI. A subscription to ChatGPT Plus is required to access Not Hotdog.
