Architecturevector-rag / Semantic Note Graph (no-folder AI second brain)

DetailsMem builds a semantic map of all user notes without folders or taxonomies, using an AI engine that reads everything written and makes it retrievable via natural language. Mem 2.0 introduced Agentic Chat that can create, edit, and organize notes via direct actions, plus Heads Up which proactively resurfaces relevant notes at the right moment. The Copilot sidebar provides live related-note suggestions as you type.
