X Alt Text Generator

X Alt Text Generator is a browser extension that helps you create alternative text for images uploaded to X (formerly Twitter). It relies on the OpenAI Vision API (gpt-4-vision-preview) to understand what your picture shows, so you never have to write image descriptions from scratch again.

The workflow is simple: after uploading an image and opening the 'Edit image description' screen, a 'Generate alt text 🪄' button appears. Clicking this button sends the image to the OpenAI Vision API, which generates a fitting alternative text and inserts it directly into the description field for you.

Instead of struggling to describe every photo you post, let the extension handle the heavy lifting. With AI-generated alt text ready in moments, your images on X become easier to describe, saving you time on every post.
