...Since Facebook uses a computer-vision model to analyse user-uploaded images and generate alt-text tags for accessibility (e.g., “Image may contain: golf, grass, outdoor and nature”), this extension surfaces those hidden tags directly in the UI—revealing what kind of information Facebook infers about images (objects present, activities being done, environment). The purpose is educational and somewhat cautionary: to help users understand the scope of visual inference and privacy issues. Once installed, the extension overlays those tags on images in the timeline, making visible what is typically hidden metadata. The project is relatively lightweight but has garnered attention due to its privacy transparency angle.
