What is Unriddle?
Anara (formerly Unriddle) is an AI-powered research workspace built specifically for scientists, students, and research teams. It helps users understand, organize, and write scientific documents with AI while maintaining academic rigor. The platform allows you to upload PDFs, Word documents, slides, audio, video, and YouTube URLs, then instantly ask questions and get concise, scholarly answers with clickable citations linking to exact locations in your source documents.
Key features include: automatic citation generation that searches academic databases like PubMed, arXiv, and JSTOR; flashcard and multiple-choice question generation from uploaded lecture slides, textbooks, or videos; a single searchable library for all research projects; cross-document analysis that finds patterns and contradictions across multiple files; Deep Search agent for multi-step research; Zotero and Mendeley integration; and support for 10+ AI models including GPT-5.4, Claude Sonnet 4.6, and Gemini 3.
Anara is designed for researchers who need accurate, source-verified information without hallucinations. Every insight links to original sources, responses are limited to uploaded files to eliminate fabrication, and the tool is trusted by 2,000,000+ researchers and students including professionals from GSK, Biogen, Goldman Sachs, Stanford, MIT, and Mayo Clinic.

Does Anara replace the need for critical thinking in research?

This ensures traceability and academic rigor.
