FakeScope is an AI Agent for automated news verification powered by **LangGraph** and **DeepSeek**. It extracts factual claims, retrieves supporting evidence, analyzes stance, and produces an explainable verdict. The repository includes the full pipeline, a **Streamlit interface**, and a **CLI utility** to run local verifications with optional telemetry via **LangSmith**.
