Never forget anything again! Your Own Personal Database Now, with Memory Vault, you always have your own personal database with you …permanently available to retrieve information you may have forgotten and want to remember. We’ve all had that frustrating experience of not being able to remember something that we know very well, but just can’t think of it: a friend’s name, a relative’s birthday, a restaurant, a favorite movie, an actor, etc. Now these slippery memories can be retrieved instantly with Memory Vault. How It Works Memory Vault stores the item you want to remember along with keywords and hints that remind you of the item and links them together. Later, although you may not be able to remember the item, when thinking of it, you will recall the keywords or hints related to it. Merely enter the keywords or hints that you do remember. Memory Vault searches your database for a match of the keyword or hint with the forgotten item and displays it. Voila! The name, place or thing you couldn’t remember is found!

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.

The clearest difference is iOS requirement: Nabuchodonosor at 16.0 against Memory Vault Plus's 18.6. On price, ads, in-app purchases and device support there is nothing between them.
