AI Improvements: AI Assistant & Smarter PICO Search

We’ve upgraded our AI-powered features to provide users with deeper insights, more relevant results, and a more intuitive search experience.
AI Assistant
The previous AI Summarize feature has been replaced with the new AI Assistant, a dropdown menu in the Discover results action bar that offers multiple AI-driven options.
Best Match Summary (formerly AI Summarize): Still summarizes top results, now clearly labeled and always available when semantic search is active
When users select 2–10 articles, even across pages, additional AI analysis options become available:
Essential Insights: highlights key findings shared across the selected documents.
Concept Discovery: reveals shared themes or keywords and suggests related searches.
Key Metrics: shows structured data like sample size, citation counts, peer review status, and more.
All findings include full references to their source articles. The AI results screen supports comparison, feedback, and a streamlined reading experience.
PICO Search: Now AI-Powered
The PICO widget now supports an AI Search mode, which translates structured PICO(T) inputs into natural language queries before running the search.
This results in more relevant, readable, and context-aware outputs—especially valuable for clinical researchers. 
Users can switch between Boolean and AI Search (if both are enabled) and admins can configure available modes via the Widget Settings panel.
