Not currently. Alt Text King writes alt text using AI based on what is actually visible in each photo, together with the product title and its variant options. It does not support a template with fields like product title, SKU, vendor, or image number.
The one thing you can control is the output language, in App settings → AI alt-text language.
If a template-based format is important to your workflow, let our support team know — it helps us prioritise.
