AI that works without internet — flights, travel, dead zones

The moment you need AI most is often the moment you have no connection — mid-flight trying to draft something, on a train writing an email, hiking and want to plan a meal, or traveling without a data plan. Cloud chatbots just spin. On-device AI doesn't care.

When "no internet" AI actually matters

• Flights. Draft, brainstorm, or study for the whole flight with airplane mode on.
• Travel abroad. No roaming or local SIM needed to use your assistant.
• Dead zones. Subways, tunnels, remote trails, big venues, basements.
• Spotty WiFi. No waiting on a server round-trip that keeps timing out.

How to use Vault AI with no connection

1. Download Vault AI before you go — one free download over WiFi and you're ready. It uses the model built into iOS, so there's nothing else to fetch.
2. Switch on airplane mode. No WiFi, no cellular — doesn't matter.
3. Use any tool. Chat, write, summarize, make flashcards, plan meals — it all runs on the device.

What still needs a connection (nothing, mostly)

Vault AI's tools run offline. The only thing an on-device model can't do is look up live information from the web — for that you'd need a connection. Everything else — writing, editing, studying, planning, thinking — works with the internet fully off.
