Build Your Own Private ChatGPT Locally — No API Key Needed

Build your own private ChatGPT-style AI assistant locally without depending on a paid API key for every conversation. In this tutorial, I show how a local large language model can power your own AI chat application while keeping more of the AI workflow under your control. This is part of a complete project where we add persistent conversations, PostgreSQL storage, document reading, RAG search, AI memory, testing, and deployment. If you want to understand how local AI assistants actually work, follow the series from beginning to end. #PrivateAI #LocalLLM #LocalChatGPT
