Ask research questions directly
Get concise, citation-backed answers generated from multiple papers
Interact with PDFs through summaries, Chat PDF, and downloads

In short: Google Scholar helps you find papers, while UPDF AI Paper Search helps you understand and use them faster.

UPDF AI Paper Search focuses on:

Direct answers to research questions with citations
Faster idea validation and early-stage research
End-to-end workflows, including searching, analyzing, chatting with, and managing papers

SciSpace emphasizes paper explanation and reading support, while UPDF AI Paper Search is optimized for research efficiency from question to insight.
