What "offline AI" actually means
The honest trade-off: a local model is smaller than the frontier cloud models. It will not match Claude or GPT on the hardest reasoning — but for drafting, search, summarization and private work, it is a strong, private workhorse.
When to go offline
- Air-gapped environments — defense, critical infrastructure, classified-adjacent work.
- Travel — flights, remote sites, patchy connectivity.
- Sensitive documents — anything you cannot send to a third-party API.
- Zero-retention policies — when even ephemeral cloud processing is not allowed.
The hybrid approach most people should use
- Offline mode for the sensitive, the travel, and the routine.
- Online routes (free/pro lanes) when you need frontier reasoning.
- Local search (/lib) for instant vault lookup at zero cost.
