# Prism

> Transform documents into explorable knowledge maps.

Prism is a document intelligence platform that turns PDFs and text into interactive, spatial knowledge graphs. Upload any document and get a Prism-generated concept map you can explore, reorganize, chat with, and use to create exams.

## What Prism Does

- **Document Processing**: Upload PDFs, paste text, or ask questions. Prism extracts key concepts and their relationships.
- **Spatial Knowledge Maps**: Concepts are displayed as draggable nodes on an infinite canvas, connected by meaningful relationships.
- **Persistent Topic Workspaces**: A single canvas can become the long-lived home base for a topic as you keep adding material.
- **Exam Generation & Practice**: Turn a canvas into an exam, choose the types of questions you want, take it in Prism, and review detailed feedback afterward.
- **Intelligent Explanations**: Each concept gets rich content: summaries, key stats, timelines, tables, and interactive visualizations.
- **Interactive Widgets**: Complex concepts get live simulations - physics demos, calculators, animated diagrams.
- **Contextual Chat**: Ask questions about any concept. Prism knows your document and gives grounded answers.

## Key Features

## Feature Deep Dive

### Spatial Knowledge Maps
- **Non-linear Exploration**: Stop reading linearly. View documents as a network of connected ideas ("leads to", "informs", "feeds into").
- **Structure Extraction**: Automatically identifies the underlying structure of research papers, contracts, or potential "rabbit holes".
- **Sketching**: Draw annotations, arrows, and diagrams directly on the canvas to organize your thoughts.

### Rich & Interactive Content
- **Deep Concept Details**: Click any node to open a dedicated detail panel.
- **Dynamic Layouts**: Prism automatically generates the best format for the content:
  - **Timelines**: For historical events or process steps.
  - **Stats & Metrics**: Key numbers extracted and highlighted in StatCards.
  - **Data Visualization**: Charts and graphs generated from textual data.
  - **Comparison Tables**: Structured breakdowns of opposing or related items.
- **Live Widgets**: For concepts that need more than text, Prism builds live, interactive simulations (e.g., physics demos, fluid dynamics solvers, financial calculators).

### Input & Processing
- **Universal Input**: Drop a PDF, paste a URL, or simply ask a question.
- **Context-Aware Chat**: Chat with your document. Prism understands the specific context of your map and concept details.
- **Progressive Research**: Add more sources and follow-up prompts as your understanding evolves.
- **Workspace Continuity**: Return to the same canvas later and continue from existing context, not from scratch.

### Exams
- **Generated From Your Workspace**: Build exams from the content already organized on a canvas.
- **Configurable Format**: Choose from multiple question types, set the difficulty, and add optional guidance before generating.
- **Focused Exam Experience**: Take the exam inside Prism without leaving your workspace context.
- **Detailed Review**: Get an overall score, letter grade, summary, and per-question feedback to see what to revisit next.
