Uploading and Analyzing Papers

Now, let’s dive into the core functionality. You can easily upload a PDF or text for analysis. Once uploaded, Unriddle AI generates questions related to the document and provides answers automatically.

For example, let’s take the paper titled “A New Approach for Dynamic Physiologic Parameter Tuning in Ant Colony Optimization and Its Application in Fuzzy Control of a Mobile Robot.” Unriddle AI generates questions such as:

  • “What is the mobile robot and why do we need to control it?”
  • “What is a fuzzy trajectory controller?”
  • “What are the advantages of using the ant colony optimization technique?”

Generating Answers

Unriddle AI generates accurate answers too. For example, when asked about a “fuzzy trajectory controller,” it swiftly provides a concise explanation of its purpose and function.

Similarly, it elaborates on the advantages of using the ant colony optimization technique, highlighting its benefits in robotics, particularly in autonomous navigation and fuzzy controller design.

Text Analysis and Upgrade Options

Unriddle AI isn’t limited to PDFs; you can also paste text for analysis. However, for extended functionality beyond the free tier, an upgrade is required. The free tier offers five credits per month, enabling the analysis of five papers.

How Unriddle AI Uses GPT-4 to Link Your Notes?

Unriddle AI operates as a note-taking application that automates the linking of ideas and notes. The secret sauce behind this functionality? GPT-4 powers it. Essentially, when you start jotting down your thoughts on a specific topic, Unriddle steps in by suggesting related ideas and notes from your existing knowledge base.

  • Automatic Linking: No more tedious manual linking with double square brackets, a common chore in other note apps. Unriddle handles this heavy lifting, saving you considerable time.
  • Automatic Resource Finding: While you write, Unriddle automatically fetches relevant resources for your topic.

For example, while discussing how fasting regulates glucose levels, I noticed that despite having documents about fasting, Unriddle failed to recognize its relevance to the topic.

Maybe it requires some processing time to refine its suggestions.

Talk to Your PDFs

AI Chat with References

The app’s interface is pretty straightforward:

  • Document Display: Left side showcases your document.
  • ChatGPT-Like Interface: In the middle, an AI interface allows you to inquire about the document or unrelated topics.
  • Your Notes: On the right, your own notes accompany the process.

As you upload a document, Unriddle AI generates a list of questions you can pose to the AI or type in your queries. This feature is a time-saver, particularly for those dealing with stacks of articles.

Furthermore, the responses come with references, an invaluable asset for students and researchers requiring accurate citations.
