Analyst Notes

Main challenge: Limited to WordPress platform; glossary terms must be defined manually or imported; primarily supports English and Chinese; no mention of AI or machine learning integration
Implementation effort: The technical piece is only part of the work; the harder question is whether Lite-Glossary plugin using PHP 7.0+, pure CSS, Vanilla JS, WordPress Transient API, DOMDocument can be owned, monitored, and reconciled in production.
Practical read: Best read as a low effort operational change with ROI upside when the pain is already measurable.
