Review the structure of an alt text draft before publishing. This tool does not inspect the image content or invent descriptions. It helps check length, clarity and common wording issues so you can write a better human description.
Start by writing an alt text draft.
The checker will review length, generic wording and common structure issues after you type.
How to use alt text responsibly
Alt text should explain the useful visual information in context. A product image, chart, portrait, screenshot and decorative background all need different treatment. Avoid keyword stuffing, vague phrases and invented details. If the image is decorative, the final page may need empty alt text instead of a written description.
A strong workflow is to draft alt text while the image is still being prepared. That way you can review the filename, dimensions, format and accessibility plan before the image reaches the CMS.

Can alt text help SEO?
Clear alt text can support image understanding, but it should be written for users and accessibility first.
