FAQ

Frequently asked questions

Which languages does the alt text generator support?

English, French and Spanish. The output language is independent of the page language, so you can write French alt text while browsing in English.

How many images can I process for free?

Ten images per day anonymously. Add your email address to raise the limit, or use DocoMatic itself for whole documents where every image gets alt text as part of remediation.

Should I use generated alt text as-is?

Treat it as a strong first draft. Machine suggestions are the floor, not the ceiling: check that the description matches what the image means in your context, and mark purely decorative images as decorative instead.
