Spindle Dynamic Glossary helps you build glossaries, dictionaries and terminology tooltips on your WordPress site.

Define a term once and it is highlighted automatically wherever it appears in your posts and pages. Visitors hover or tap to read the definition in a tooltip or pop-up, and a searchable A-Z glossary can be added to any page with a shortcode.

Features

Automatic highlighting in the post types you choose, every mention or just the first.
Safe matching that never touches links, headings, buttons, scripts, code samples, shortcodes or HTML entities.
Accessible tooltips and pop-up: keyboard and screen-reader friendly, dismissible with Escape, and kept on screen automatically.
Searchable A-Z glossary with live search and a letter menu.
Dashboard with a setup checklist, statistics and status at a glance, and a settings screen with a live tooltip preview.
Fonts: choose Poppins, Josefin Sans or the WordPress default for the plugin’s screens, and optionally use the same font for tooltips, the pop-up and the glossary on your site. Both fonts are included, so nothing is loaded from other websites.
Per-post opt-out from the editor sidebar.
