🎯 Themes #
Choose any of the following themes for your submission:
🧠 1. AI (API or In-Browser) #
Participants can:
- Use AI APIs (like OpenAI, Cohere, HuggingFace Inference API, AssemblyAI, etc.)
- Or run models fully in-browser (e.g., WebLLM, TensorFlow.js, ONNX.js) for a bonus.
🔹 Theme Ideas: #
| Project Idea | Description |
|---|---|
| EmotionCam | Use webcam and either an API (e.g., Affectiva) or browser ML to detect facial emotions. |
| Ask My Doc | Upload a PDF and ask questions via LLM (OpenAI API or WebLLM). |
| Smart Summarizer | Paste an article or video transcript → get summary + key points. |
| Voice Commands Bot | Use browser mic + API (e.g., Whisper) to recognize voice commands and reply via LLM. |
| Chat with Spreadsheet | Upload Excel/CSV and query it using an API-backed LLM (like GPT). |
| Browser Tutor (Bonus) | A tutor bot that runs entirely in the browser using WebLLM + math.js. |
| In-Browser Classifier | Use TensorFlow.js to build a working image or gesture classifier. |
| Hybrid AI Agent | Use both browser and API AI — e.g., do vision in-browser, NLP via API. |
🎁 Bonus Points: Fully browser-based AI using WebGPU/WASM, etc. #
📊 2. Dashboarding & Visualization #
Use Plotly.js, D3, Chart.js, ObservablePlot, or WebGL-powered visualizations.
🔹 Theme Ideas: #
- Smart City Dashboard: Combine open datasets (air quality, traffic, weather) into a live dashboard.
- Crypto Tracker: Live charts of top coins, sentiment analysis of news/Twitter, and prediction trends.
- Personal Health Tracker: Allow users to input or import fitness/health data and visualize trends.
- Startup Metrics: Simulate or import mock metrics for user growth, churn, revenue, and visualize with cohort analysis.
- Election Pulse: Build a polling dashboard with real-time visualizations and projections.
🕶️ 3. XR (Extended Reality in Browser) #
Use face-api.js, TensorFlow.js, WebXR, Three.js, A-Frame, or AR.js.
🔹 Theme Ideas: #
- Try-on Filters: Real-time face tracking with filters, masks, and effects — like Snap or Insta, but in a notebook!
- AR Info Cards: Point camera at objects (e.g., books, plants) and display interactive labels or facts.
- 3D Math Visualizer: Use A-Frame to render 3D plots or vector operations in real space.
- Virtual Whiteboard: Collaborative whiteboard inside Scribbler using Three.js and drawing APIs.
- Face-Controlled Games: Build simple browser games controlled by head movement or eye blink.
