➡️Built a modular personal AI chatbot that delivers smart, helpful replies and supports web search, speech synthesis, and voice assistant capabilities. ➡️Used LangGraph to orchestrate model interactions (OpenAI, Groq) with clear separation of frontend, backend, and AI logic. ➡️Integrated environment variable handling via .env and managed dependencies with Pipenv. ➡️Provided a simple local web UI using Streamlit for direct interaction. ➡️Designed for extensibility with support for gTTS (text-to-speech), Twilio/Vapi voice assistant integration, and future multi-language support.
