Alt text, also known as “alternative text” or “alt tag”, is used to describe the content of an image on a web page, and is especially important for people with visual impairments who rely on screen readers to navigate the web.
Many AI tools can generate alt text these days; they analyse an image and automatically generate a description. Having a tool to assist with alt text could be a good starting point, especially for non-native speakers and those without a wide vocabulary.
My experience with alt text AI tools so far is still in the research stage, so I am not in the position to convincingly recommend any of them. But I believe there are a few tools that help with alt text and much more that may be worth exploring 🔍.
Computer Vision | Microsoft Azure — azure.microsoft.com
An Azure Cognitive Service, it extracts rich information from images and analyse content with Computer Vision.
Machine Learning Image and Video Analysis — Amazon Rekognition — Amazon Web Services — aws.amazon.com
Amazon Rekognition automates image and video analysis for your applications and is easy to implement without machine learning (ML) experience.
Vision AI | Cloud Vision API | Google Cloud — cloud.google.com
Derive insights from images with AutoML Vision, use pre-trained Vision API models, or create computer vision applications with Vertex AI Vision.
In any case, we should always review the alt text generated by AI to ensure that the information provided is accurate and context-based, and, when necessary, manually adjust it.
