Image Alt Text Writer

This tool arranges words you supply — a subject, an action, a setting, a detail — into alt text of the right shape and length, and returns the finished <img> tag around it. It does not look at your picture: there is no vision model behind this page, whatever the name suggests.

What happens is sentence construction. The fields are ordered detail, subject, action, setting, sentence-cased, trimmed to your character limit on a word boundary rather than mid-word, and returned as both a concise and a descriptive variant. No file is read, uploaded or analysed, and no computer vision runs at any point — a file attached to the form is counted and ignored, and the output says so in as many words. Marking an image decorative returns an explicitly empty alt="" instead, which is the correct markup for one, and never a deleted attribute.

Everything happens in the page from the words you type. Nothing is uploaded, including an image you attach: it is discarded without being read, because there is nothing here that would read it.

Writing consistent alt text across a product gallery, getting the phrasing right for an image you can see but struggle to describe briefly, marking spacer and background images decorative correctly, and cutting an over-long alt to the length a screen reader will announce.
