About AnswerThis
AnswerThis is a web-based AI research assistant for literature reviews and academic writing. It searches a corpus the company describes as 250M+ papers (some pages say 300M+), extracts findings from them, and drafts literature reviews in which each claim links back to a source passage. The site says unsourced claims are removed and each claim is checked against its source.
Best for
- Literature reviews with traceable citations, systematic reviews, managing a paper library, and drafting academic manuscripts
- Literature Review Drafting: Entering a research question and getting a cited review to verify and edit.
- Systematic Review: Running screening and PRISMA reporting with a second reviewer in a lab workspace.
- Thesis Writing: Collecting papers in a library and drafting sections with citations in the AI Writer.
- Clinical and Pharma Research: Combining papers, trial registries and regulatory sources for landscape analysis.
- Institutional Rollout: Libraries deploying a campus-wide license with SSO.
Not ideal for
- Users who need a mobile app or a documented public API, or who want a general-purpose chatbot
