What is Ai2 Asta?
Ai2 Asta is a scholarly research assistant built by Ai2, the non-profit Allen Institute for AI that also runs Semantic Scholar. It draws on more than 108 million paper abstracts and over 12 million full-text papers to help you find, summarise and analyse scientific evidence.
Asta brings together tools that Ai2 first released on their own. Paper Finder is an AI literature search that works through a question the way a researcher would, follows citation trails and explains why each paper is a good match. Summarize literature (formerly Scholar QA) turns a research question into a structured written overview with real citations you can check. A data analysis tool is also being tested with selected partners. Because every answer points back to papers, it is a useful starting point for a literature review rather than a replacement for reading the sources.
