Overview
Semantic Scholar is a free AI-powered academic search engine from Ai2 with paper discovery, citation context, influential-citation signals, summaries, research feeds and public scholarly-data APIs. Its large graph helps researchers navigate literature, but coverage gaps, automated metadata, opaque ranking and links to inaccessible full text mean systematic reviews still need multiple databases and manual verification.Best for
