marswangyang/personal-ai-memory
A local-first Chrome extension that passively captures ChatGPT, Gemini, Claude, Grok, Perplexity conversations into a private memory graph. Features in-browser Hybrid RAG (Vector + BM25), semantic search, and 100% privacy via WebAssembly and IndexedDB. No servers, no API keys.
Builds semantic memory through ONNX-based embeddings computed directly in the browser, combining vector search with time-decay weighting and BM25 keyword indexing via Reciprocal Rank Fusion for dual-modality retrieval. Supports exporting full conversation backups as JSON with embeddings, importing them into the local IndexedDB store, and a Trie-powered favorite prompt system with folder organization—all without leaving the client.
