AnswerThis
AI research assistant with answers across 250M+ academic papers.
About
AnswerThis searches a database of more than 250 million academic papers and returns evidence-backed answers with line-level citations, plus paper summaries, citation maps, and bibliometric analysis. It targets the full literature-review workflow: semantic search, chat with documents, paraphrasing with citation support, and BibTeX export with Zotero/Mendeley integration. A free plan covers light use (a handful of credits per month); Premium runs about $21/year on annual billing or $35/month monthly, with an Enterprise tier for institutions. Like any answer engine, its citations point to real papers, but the synthesis between them is AI-generated and should be checked.
