GUIDE · Offline / Local AI

Offline AI for private writing

If you want AI help without leaking manuscripts or research, use an offline AI USB. It keeps drafting, outlining, and editing local to your machine with no cloud calls.

No cloud telemetry; works in airplane mode.

Preset styles for brainstorming and editing offline.

Portable between home and travel laptops.

Who this is for / not for

For authors, journalists, and creators who need privacy. Not for teams collaborating live in cloud docs where real-time co-authoring is required.

  • Use it when NDAs or embargoes block uploads.
  • Skip if you rely on cloud version history and collaboration.

Specs that actually matter

A modern CPU with 8–16 GB RAM and a USB 3.0 port is enough. GPU is optional. Keep 4 GB free for drafts and caches.

  • Balanced preset suits long-form editing.
  • Fast preset is best for idea generation on light laptops.
  • Use a direct USB port to avoid disconnects mid-draft.

Private writing workflow

Store drafts on the USB, run in airplane mode, and use prompts tailored for outlining, rewriting, and sensitivity checks. Export versions manually to your preferred editor.

  • Save prompt templates for tone and POV.
  • Use short outputs when drafting on battery to keep temps low.
  • Back up finished drafts to an encrypted drive, not cloud sync.

Common pitfalls

Accidentally saving to synced folders. Relying on a single USB without backup. Updating models mid-project and changing output style.

  • Pause sync apps during offline sessions.
  • Keep a duplicate USB for redundancy.
  • Lock in a preset per project to keep tone consistent.

PortableMind vs DIY

DIY means juggling model downloads and UI choices, risking leaks through misconfigurations. PortableMind is preloaded and offline-first, so you draft without cloud accounts.

  • No telemetry or hidden API calls.
  • Consistent style presets across machines.

Keep the writing rig steady

Test start times on your main laptop and travel laptop. Keep a small printed quickstart in your notebook. After sessions, clear cache and safely eject to avoid corruption.

  • Use battery mode presets on the road.
  • Keep a second cable in your bag.
  • Label the USB so you don’t mix it with general storage drives.
