Show HN: A local, open-source personal database with AI superpowers (superego.dev)

Superego is an open-source, local, encrypted personal database designed to act as a private vault for all your personal records and to be directly connected to an AI assistant. The pitch: keep data on-device and under your control, then let an AI query and reason over that data so it can surface personalized insights ("you run faster on Thursdays," or "you spent €632 on shoes last year"). It’s intentionally hackable — you can extend it with custom apps or ask the AI to generate integrations — and positioned as a developer-friendly platform for building private, personalized agents. For the AI/ML community this matters because it pushes personalization and retrieval-augmented workflows toward a privacy-first, local-first model. Technically, Superego implies a stack combining an encrypted local store, indexed retrieval (likely embeddings/vector search), and a layer that translates user intents into retrieval and actions; openness enables audits and community-built plugins. That architecture lets models deliver context-rich answers without leaking raw data to cloud services, but it also raises practical trade-offs around secure key management, model hosting (on-device vs. cloud), latency, and update/consistency semantics. Overall Superego is significant as a building block for trustworthy, extensible personal AI assistants that keep data in users’ hands.
