AnswerThis
AI literature review assistant with a library and writer
What is AnswerThis?
AnswerThis is an AI research assistant built around literature reviews. It searches a database the site puts at more than 300 million papers and sources, answers questions with citations that link to the exact passage, and keeps saved papers in a library that syncs with Zotero and Mendeley. An AI Writer drafts documents with citations in more than 2,000 styles, and higher plans add a systematic review pipeline with screening, data extraction and PRISMA reporting.
