# StudyLens

> StudyLens is an AI-powered study guide generator. Users upload documents, images, or PDFs and receive comprehensive, structured study materials generated from the content of their files.

## What StudyLens Does

- Accepts uploaded files: PDFs, images (JPG, PNG, etc.), and text documents
- Extracts text from images using OCR (including Mistral Vision for handwritten or low-quality scans)
- Generates two types of AI study materials from the extracted content:
  1. **Full Study Guide** — includes key concepts, practice questions (Conceptual, Application, Analysis), and detailed explanations
  2. **Flashcard Set** — 15–25 in-depth flashcards covering the material in a question-and-answer format
- Users can save, export, and review their generated guides
- Supports multiple AI providers: OpenAI (GPT-4) and Mistral AI (via OpenRouter)

## Who It's For

Students, educators, and self-learners who want to turn their notes, textbooks, or study materials into ready-to-use study guides or flashcard decks — without doing the formatting work themselves.

## Key Pages

## Important Details
