Alt text checker for small US agencies

See the alt text on one public page before you rewrite it.

Paste a URL. AltReview reads that page's static HTML, flags missing and placeholder alt text, and — when a model key is configured — drafts replacements for at most 10 images. You review every draft. The site is not changed.

  • Free: one public URL, rule checks on every image in that HTML, visual review of at most 10 images.
  • Credit packs, priced and not yet on checkout: $19 for 250 image occurrences, or $39 for 1,000. The same image on two pages counts twice.
  • Privacy policy: what is stored, how long it stays, and how to delete it.

One http or https page. Ports other than 80 and 443 are refused. Private addresses, metadata hosts, and redirects onto them are blocked. JavaScript on the page is not run.

Missing, empty, and wrong

A missing alt attribute is a different finding from alt="". Empty alt is often right for decoration. A filename such as IMG_1044.jpg is present and still a poor description. The guide walks through the difference.

An alt text generator that waits

When OPENAI_API_KEY is set, up to 10 images are sent to gpt-5.4-mini after they are scaled to fit inside 512 pixels. Drafts are not approved by default. Without the key, the checker stays on rule checks and says so.

Bulk alt text is priced, not running

A bulk alt text generator for a CSV of pages is the paid workflow: 100 pages or 1,000 image occurrences per project, whichever comes first. Checkout is not connected in this preview. See the prices and join the waitlist.
