AI Usecase Demo — Personal Project by Duncan Krebs

AI-powered document analysis demo that showcases:

• 📄 PDF text extraction
• 🤖 Local LLM analysis using Ollama (no API keys needed)
• 🛠 FastAPI backend for easy integration into apps or frontends
• 💡 Example use case: Contract deviation detection, but easily adaptable to other document AI tasks.

• Local AI Inference — works fully offline with llama3 or any Ollama model
• REST API — ready to plug into a UI or automation pipeline
• Extensible — replace prompt templates, add embeddings, or hook into Hugging Face models
