Supports:
– Bulk generation
– Single generation
– Auto-generation on upload
– Media Library buttons

🔹 Automatic Captions & Descriptions

Fills in an image’s caption and description whenever they are left empty, using the same source chain as ALT text, for:
– Better SEO

Existing captions and descriptions are never overwritten.

A complete admin UI showing:

– Status indicators
– Quick one-click fixes

🔹 Centralized Settings Page

Every behavior above — sources used, auto-generation toggles, WebP quality, original-file handling, excluded folders — is configurable from one Settings screen. No editing options in the database required.

🔹 Performance-Focused

🤖 AI-Powered Generation (Coming Soon)

A future release will let you connect an OpenAI or Anthropic Claude API key and choose which model generates your ALT text, captions, and descriptions — for richer, context-aware results beyond the current EXIF/filename/title chain. A preview of this option is already visible (disabled) on the plugin’s Settings page.
