Open Bible hover cards powered by your own WordPress database. No remote lookup is needed during page views.
Installed Texts
Install any combination of local Bible texts. Installed translations are automatically available in frontend tooltip tabs; the default translation only controls which one opens first.

Open Text Policy
This plugin is designed for Bible texts that are public domain, openly licensed, or otherwise legally permitted for local storage and display. It does not provide import tools for restricted commercial translations unless a future integration explicitly supports proper licensing.
The built-in importer currently supports selected open/public-domain eBible VPL packages.
