Memento – Self-hosted agentic search and LLM wiki over your email

Memento is a self-hosted tool that indexes your entire email history (100K-500K messages) to create a searchable, LLM-powered wiki of your life, projects, and connections. It’s designed for power users who want to turn their inbox into a personal knowledge base, enabling agentic search and chronological exploration of decades of data. The project is interesting because it reframes email as a rich, untapped proxy for personal history, offering privacy-focused, AI-driven recall without relying on cloud services.
