Alt text for every image, in one go.

Drop your images. Each one gets alt text within your character limit, a longer description and a social caption, written for the page it will sit on and checked for the usual mistakes. No API key needed: pay per run with credits.

Used for Alt text limit chars Caption for Language

See an example free A cafe blog post with five images: a photo, a chart, a text card, a decorative divider and an icon button.

Which alt text does an image need?

Adds nothing a reader would miss (a divider, a texture)? Decorative: alt="", so screen readers skip it.
A link or button with no text? Say what it does: "Search", "Download the menu".
Mostly text (a poster, a quote card)? Put the text in the alt.
A chart or diagram? A one-line takeaway in the alt, the data in a description or table nearby.
Anything else: what it shows that matters on this page, in a sentence. Skip "image of": screen readers already say it.

WCAG 2.2 success criterion 1.1.1 asks for a text alternative that serves the same purpose. It sets no length; about 125 characters is a common house limit so alt text stays a glance, and longer detail goes in a description.

How it works

Your images are shrunk in the browser to 1280 px (location data dropped) and read by an AI model, up to six per run.
It decides what kind of image each one is, then writes alt text, a description and a caption for your page and platform.
Your browser checks every alt text for length, "image of", file names, placeholders and missing text. Edit any field and the checks re-run.

Before a run you see the most it could cost (reserved); you are charged what it actually used, usually less.
