Analysts frequently sift through reports, whitepapers, and internal documents. Unriddle AI accelerates this process by providing summaries, insights, and Q&A capabilities—all helping professionals focus on interpretation and strategy instead of manual reading.

Key Features of Unriddle AI
Unriddle AI comes packed with tools that help you get more from your PDFs in less time. From smart search to instant summaries, each feature is designed to remove friction and give you exactly what you need—without information overload.
AI-Powered Question Answering
With Unriddle AI, you can ask questions about your PDF just like you’d ask a person. Whether it’s “What are the key takeaways?” or “What does Section 3 talk about?”, the AI gives you direct, context-aware answers. This means no more scrolling aimlessly or trying to remember what page something was on. It’s especially useful for long documents where searching manually would take forever. You get instant clarity and can zero in on the information that matters most.
Smart Summarization
Unriddle AI can break down entire PDFs or individual sections into clear, concise summaries. Instead of reading dozens of pages, you can quickly scan the main ideas and decide what to dive deeper into. This is a game-changer for time management, especially when you’re handling reports, whitepapers, or legal documents. The AI understands tone, structure, and key points—so the summaries feel natural and not robotic. It’s like having a fast-forward button for reading.
Semantic Search
Unlike traditional search tools that rely on exact keywords, Unriddle AI uses semantic search to understand meaning and context. This means you can search for ideas, concepts, or even vague terms and still get accurate results. For example, if you search “main challenges,” the tool knows to find related phrases like “primary issues” or “key problems.” It helps you find what you’re looking for, even if you don’t use the exact language from the document.
Topic Detection and Breakdown
Unriddle AI automatically breaks your document into logical topics, helping you navigate it more easily. It identifies sections, headers, and shifts in content so you can jump straight to what’s relevant. This is especially helpful in longer PDFs where manual navigation is slow and inefficient. With this feature, you can browse your document like a table of contents—with intelligence behind it. It keeps your workflow smooth and organized.
Highlight and Note Tools
While reading, you can highlight key points or add your own notes directly within Unriddle AI. This allows you to mark insights, flag questions, or save important takeaways as you go. If you’re collaborating with others or planning to revisit a document later, this becomes incredibly valuable. Your highlights and notes are stored for easy access, so you don’t lose track of what’s important. It brings an element of control and personalization to the reading experience.
