Hi HN! I built ChatVault after struggling to find specific conversations in my 10+ months of Claude AI chat history. ChatVault imports your exported conversations, stores them locally (SQLite + ChromaDB), and provides: ∙ Semantic search using sentence-transformers ∙ RAG-powered Q&A with local Llama 3 (via Ollama) ∙ Full privacy - nothing leaves your machine Built with Python/FastAPI + React. MIT licensed. GitHub: https://github.com/rajz3006/ChatVault The RAG implementation is basic but effective - uses conversation context windows and re-ranks results. Would love feedback on the embedding approach or the chunking strategy. Currently supports Claude exports, but the architecture should work with any chat JSON format with minor changes.
