Unriddle

Anara (born as Unriddle) is a strong contender in the academic AI space, especially after the Anara 3.0 update in April 2026. The core value proposition is simple: upload files, ask questions, get answers with citations. This eliminates a major pain point for researchers—hallucinated references. The agent sidebar in 3.0 allows you to delegate multi-step research tasks like literature reviews or competitive landscape mapping, reviewing up to 100,000 files autonomously. The platform supports a wide range of models across tiers (GPT-5.5, Claude Sonnet 4.6, Gemini 3.1 Pro, Claude Opus 4.7 on Max) so you can choose based on accuracy vs. speed. File import limits scale from 20 MB/120 pages on Free to 500 MB/unlimited pages on Max. Connectors include Zotero, Mendeley, Google Drive, Notion, OneDrive, and SharePoint (live sync on higher tiers). The free tier is genuinely useful for testing but restrictive—2,000 AI words/day and 5 uploads/day. Pro tier at $20/month (yearly) unlocks unlimited words and imports, making it the sweet spot for active researchers. The biggest weakness is the academic focus: if you need real-time web search or non-academic data, it falls short. The rebrand from Unriddle to Anara may cause confusion, but the product improvements justify the change. Overall, it's a reliable, citation-focused research assistant that integrates smoothly into existing academic workflows.

Anara (formerly Unriddle) is an AI-powered research workspace designed for scientists, students, and research teams who need rigorous, citation-backed analysis. Upload dense academic papers, textbooks, clinical studies, and other files, then ask questions and receive concise answers with clickable citations directly linked to original sources. Unlike general AI tools that hallucinate, Anara only responds from uploaded files, eliminating made-up references. Key features include automatic citation generation, literature search across PubMed, arXiv, and JSTOR, and the ability to generate flashcards and multiple-choice questions from uploaded materials. It integrates with major academic databases and supports file types including PDF, DOCX, images, and video. With over 2 million researchers and students using the platform, Anara positions itself as a specialized alternative to tools like ChatPDF or Elicit, prioritizing accuracy and academic rigor over broad utility. Notable recent updates include Anara 3.0 (April 2026) with autonomous agents capable of reviewing up to 100,000 files, a rebuilt note editor, folder-level instructions, and integration of @web toggle replacing @search papers. As of May 2026, the platform offers models like GPT-5.5, Claude Sonnet 4.6, Gemini 3.1 Pro, and on Max tier Claude Opus 4.7.
