About

Nabuchodonosor

Features
Read full description

Your model. Your rules. Nabuchodonosor is a private chat interface that connects to the AI engine you choose: Ollama on your local network or Tailscale, or an OpenAI-compatible API available over HTTPS. FREE AT THE APP LAYER The app sends your requests to the model without rewriting, moderating, or adding refusals. Final behavior remains that of the model and provider you choose. EPHEMERAL BY DEFAULT Messages stay in memory only. No history is written to your iPhone. Background clearing is enabled by default. Recent context is off by default; if enabled, it remains limited to this session and 12,000 characters. BRING YOUR OWN MODEL Enter any model name, use an Ollama token provided by the Mac app, or add a key for your compatible server. Secrets are protected in this iPhone’s Keychain and are not synchronized. VERIFIABLE PRIVACY No Nabuchodonosor account. No analytics, telemetry, uploaded crash reports, or cloud sync. The network session uses no caches or cookies. Important: every request is sent to the engine you configure. If you choose a remote service, its retention practices and restrictions depend on that provider, not Nabuchodonosor.
