About AI CogniSphere
CogniSphere is a knowledge graph tool designed to help you organize notes, study materials, images, and PDFs in one place. Capture content with your camera, import images from your photo library, or add PDFs, then use OCR to extract text and AI to assist with drafting knowledge points before saving them to your personal knowledge base. You can also create knowledge points manually and build connections at your own pace. Each node can include images, PDFs, text notes, web links, and voice memos, making it easier to turn scattered information into a structured body of knowledge. The interactive graph supports dragging, zooming, and multiple layout options, so you can explore relationships between ideas from both a big-picture and detailed view. It is useful for reading notes, class materials, research organization, and personal knowledge management. Use CogniSphere to: Organize study notes and learning materials Build topic-based knowledge structures Keep images, PDFs, and notes connected in one context Review how concepts relate to one another visually Continue your workflow across iPhone and iPad Data can sync across compatible devices so you can continue organizing wherever you work. Some AI, OCR, PDF summarization, website preview, sync, or subscription-related features may process relevant data only when you actively use those features and only to the extent necessary. Actual features, pricing, and terms are shown in the app. Privacy Policy: https://eric1207cvb.github.io/CogniSphere/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
