🛠 Tech Stack

Frontend:

• Next.js (App Router)
• Tailwind CSS + shadcn/ui
• TypeScript

Backend:

• FastAPI (Python)
• LangChain (for LLM integration and agent logic)
• Pinecone (vector database for embeddings)
• Supabase (auth + DB for metadata)

AI Models:

• OpenAI GPT-4 or Hugging Face Transformers (configurable)

🧬 How It Works (Internal Architecture)

User Uploads PDF 
    | 
    v 
Text Extractor (PyMuPDF / PDFplumber) 
    | 
    v 
Chunking & Embedding Generator (LangChain + OpenAI/HF) 
    | 
    v 
Embeddings stored in Pinecone (vector DB) 
    | 
    v 
User asks a question 
    -> LangChain QA chain retrieves chunks 
    -> LLM generates answer 
    -> Response shown in frontend

Bonus: Metadata is stored in Supabase (file name, upload date, user ID) for traceability.

⚙️ Getting Started

1. Clone the repo

git clone https://github.com/your-username/askwiseo.git
cd askwiseo

2. Set up environment variables

Create a .env file for both frontend and backend:

.env (FastAPI)

OPENAI_API_KEY=your_key
PINECONE_API_KEY=your_key
SUPABASE_URL=your_url
SUPABASE_SERVICE_ROLE_KEY=your_key

.env.local (Next.js)

NEXT_PUBLIC_SUPABASE_URL=your_url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_key

3. Run the backend (FastAPI)

cd backend
uvicorn main:app --reload

4. Run the frontend (Next.js)

cd frontend
npm install
npm run dev
