Zotero doesn't have native AI features. The best plugins are PapersGPT for PDF chat, Aria for research assistance, and Beaver for agentic search. For deeper integration, tools like PapersFlow sync with Zotero and add AI without plugin configuration.

TL;DR: Zotero doesn't have native AI features. The best plugins are PapersGPT for PDF chat, Aria for research assistance, and Beaver for agentic search. All require API key configuration. For built-in AI without setup, PapersFlow's Zotero alternative page shows the sync-based workflow.
