Nova 2 is a native macOS companion for an analyst who writes sourced notes. It turns a one-line request into a structured context note (bottom line up front, tagged evidence bullets, scenarios with triggers, recommendations): it plans the research, reads the full text of every source it cites, drafts with Muse Spark 1.3 at maximum reasoning, and has Meta's open-weight Muse Spark Open independently review the draft (facts, evidence tags, score). A complete note costs about $0.24 including the review. Around that core, Nova keeps the day in one calm place: live voice you can interrupt, mail and agenda triage where nothing is sent without approval, hidden prompt injections flagged, background agents that prepare work, image generation and a hard, fail-closed monthly budget. Measured on our 21-case reliability bench: 21/21 passed, 54/54 citations correct, $0.45 per full run. Every model it calls at runtime is a Meta model; the submitted code contains no other model provider, and a proof journal logs every model call.
