Image Alt Text Writer

BeginnerwritingMinimum 16K context

Writes concise, useful alternative text for images that conveys the information a sighted reader gets from them. Adapts to context (informative, functional, decorative, or complex images), recommends empty alt for purely decorative graphics, and produces longer descriptions plus captions for charts and diagrams where a short string is not enough.

Use cases

  • Writing alt text for product and editorial images
  • Deciding when an image should have empty alt text
  • Describing charts and diagrams beyond a short alt string
  • Auditing existing alt text for redundancy or missing information

Example prompt

Write alt text for the attached images.

For each one: state whether it is informative, functional, decorative, or complex; give the alt
text (or explain why empty alt is correct); and for any chart or diagram add a longer description
that conveys the data trend. Keep alt text short and avoid phrases like "image of".
