--- status: raw tags: - search title: life search type: idea updated: 2026-04-11 visibility: public --- # life search the `mgrep` for your entire life — a semantic search engine over all your personal data. you type a query like "what was that restaurant in tokyo" or "when did i talk to sarah about the internship" and it searches across notes, emails, messages, calendar events, photos, documents, and browser history to surface the actual memory. the gap it addresses: you know you experienced or captured something, but locating it requires remembering which app it lives in and which search syntax to use. that friction is high enough that most people just give up. the technical approach would be a unified ingestion pipeline that chunks and embeds data from all sources into a single vector store, then exposes a natural-language query interface. the indexing layer is the hard part — connecting to all data sources (Apple Messages, Gmail, Notes, Obsidian, browser history, photos via OCR/CLIP) and keeping embeddings fresh. the search layer itself is relatively straightforward once data is in a common format. a local-first design would be important for trust: this is maximally sensitive personal data and running it through a cloud service would be a non-starter for most people. related: [[axon|axon]], [[universal-data-capturer|universal data capturer]], [[me-model|me model]], [[always-on-ai-assistant|always-on AI assistant]]
