FAQ
-
Do I need to register or create an account?
-
No. The free trial starts instantly with one click. For BYOK mode, just paste your OpenAI API key.
-
Is there a free plan?
-
Yes. 25 free tokens are included. After that, use your own OpenAI API key (unlimited, free) or upgrade to Pro.
-
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.
Rezensionen
26. November 2025
I started using ai alt text builder 2 days ago and it honestly made my life easier. One click and it writes clean, descriptive alt text that ACTUALLY makes sense. The score badge is a nice touch, and the bulk generation saved me so much time. I also love that I can pick the language. Overall, it just works and does exactly what you need. After trying 20 different plugins, I finally found my favorite!
