Nidra

Nidra (Sanskrit for "sleep") is a self-hosted personal assistant that learns who you are from what you actually do online, then sleeps on it. A privacy-first browser extension captures the signals: what you read, what you search, your calendar and email activity. It runs on Chrome and iOS Safari from one codebase, and everything stays on your own hardware. Password and payment fields are never captured, and banking or auth sites are skipped entirely. Two layers sit on those signals. Opinions are grounded beliefs about you, each with a confidence score and a link back to the evidence (read a dozen Rust articles, so probably into Rust). Dreams are the nightly sleep pass: an on-device model (Gemma, via Ollama) reads your recent activity and makes a leap heuristics can't. Flight searches, a car rental, and some reading about ryokans become "probably planning a trip to Japan." What keeps it honest is one rule: a dream never becomes a belief by itself. It has to be confirmed by something you do later, and dreams nobody acts on expire. Over many cycles the system gets better at dreaming, judged against what really happened instead of grading its own work, which is the failure mode that quietly breaks most self-learning systems.
