Unriddle

Unriddle is an AI research assistant that creates an interactive chat interface around academic papers, PDFs, and documents. Upload a paper or paste a URL and you can ask questions about the content, request plain-language explanations of complex sections, and extract key findings without reading the entire document. The tool is tuned for dense academic language and technical writing, handling domain-specific jargon better than general-purpose chatbots. Unriddle can process multiple documents simultaneously and identify connections between them, which is useful for literature reviews where you need to synthesize arguments across many sources. It generates summaries, highlights key claims and findings, and lets you build a persistent knowledge base from your research library that accumulates across sessions. Unriddle is used by graduate students, researchers, and knowledge workers who need to process large amounts of academic content efficiently. It occupies similar ground to Elicit, SciSpace, and Consensus but focuses more on general document comprehension and synthesis rather than structured database queries. The chat interface is more flexible for exploratory reading, while tools like Elicit are stronger for systematic literature reviews.
