StudyLens

StudyLens is an educational productivity tool built using Python and Streamlit. It enables students to upload their study notes and generate learning aids such as summaries, mind maps, flashcards, and quizzes — all within a user-friendly web interface.

Features

• Upload Notes: Supports .pdf and .txt files. Extracts text content for processing.
• Summary Generator: Implements frequency-based summarization using NLTK to condense text.
• Mind Map: Dynamically creates mind maps from input text using Graphviz.
• Flashcards: Generates keyword-based question-answer flashcards for active recall.
• Quiz Generator: Forms simple multiple-choice questions based on extracted terms and context.

Technologies Used

• Python
• Streamlit – Web UI framework
• NLTK – Natural Language Processing for text analysis and summarization
• Graphviz – For visual mind map generation
• PyPDF2 – To read and extract text from PDF files
• nest_asyncio – To patch event loops in Streamlit for async support
• Regular Expressions – For basic keyword and pattern detection

How It Works

1. User uploads study material (PDF or text).
2. The app extracts content and lets the user choose between:
   • Generating a summary
   • Creating a mind map
   • Generating flashcards
   • Taking a quiz
3. Each module is loaded dynamically using Python's importlib and displayed via the sidebar navigation.

Limitations

• Summary and quiz logic are rule-based and may not cover deep semantic understanding.
• Flashcard generation may miss nuanced Q&A if input text lacks clear definitions.

Future Scope

• Integrate large language models (e.g., GPT) for smarter content generation.
• Enable user account login and save study sessions.
• Add diagram/image-based support for mind maps.
