External services
This plugin connects to RankPilotAI’s API to generate ALT text and to fetch token status.
What is sent and when
- On explicit user actions only (Generate button or Bulk): image URL, file name, current ALT (if any), selected model, selected language, site URL and domain, plugin slug, and your Site Token.
- On token-status checks in the settings page: Site Token, site URL and domain, and a minimal request context.
Why it is sent
- To generate the requested ALT text and return it to your Media Library item
- To authorize usage and show your remaining balance

FAQ
-
Is there a free plan?
-
Yes. A limited free tier is available. Higher tiers provide more tokens and additional models.
-
Does it overwrite my existing ALT texts?
-
Only when you click Generate for a given image (or run a bulk action). It writes to WordPress’ standard
_wp_attachment_image_altfield. -
What languages are supported?
-
English, German, French, Spanish, Turkish — plus Other/Custom. Enter any language name and we’ll pass it to the generator.
-
Will it change image file names or titles?
-
No. It only sets the ALT text and stores a score
_aatb_scoremeta (for the badge/column). -
Does it work with other media/SEO plugins?
-
Yes. ALT text is a core WordPress field, so other plugins and themes will read it normally.
