Stemly
Scan. Analyze. Visualize. Study.
An AI-powered STEM learning platform that transforms diagrams and problems into interactive simulations, study notes, and smart quizzes.
The Problem
Students struggle to visualize abstract STEM concepts from textbooks and static diagrams. Traditional tools offer either theory OR visuals, rarely both in an interactive, personalized way.
Our Solution
Scan any physics problem with your phone, and Stemly instantly generates:
- AI Visualiser — Real-time, parameter-driven physics simulations with interactive sliders
- AI Notes — Comprehensive study notes with formulas, examples, and resources
- Smart Quizzes — Auto-generated MCQs to test understanding immediately
- AI Tutor — Chat with Gemini, GPT-4o, Grok, or Llama 3 for personalized help

Features
AI Visualiser — Not Just a Video
A real-time physics engine with:
- Interactive control via sliders (velocity, angle, gravity, resistance)
- Natural language control — ask "What if gravity was 0?" and watch it update
- Live graphs (velocity-time, position-time, acceleration-time)
- 9+ simulations: Projectile Motion, SHM, Optics, Kinematics, Free Fall, and more
AI Notes — Study Smarter
Generated specifically for each scanned problem:
- Concept breakdowns with simple explanations
- Key formulas with physical meanings
- Step-by-step worked examples
- Curated resources from across the web
Smart Quizzes
- Instantly generated from your scanned content
- Multiple-choice with detailed explanations
- Score tracking and feedback

How do I choose a repository?
Start with your use case, compare repository activity, and check the original project before adopting it.
- Search by repository name, owner or description, then narrow the results by topic.
- Compare stars, forks and recent pushes. Stars show community interest, not a guarantee of quality.
- Read the README, license and issues on GitHub before using a project.
