What it is

A private AI that knows your documents.

Most AI tools are powerful but general. They know everything except your work — your contracts, your research, your files.

PAI is different. You upload your documents once. The AI indexes them locally on the USB drive and answers questions about them with exact citations.

Need more processing power? You can switch between built-in local AI or advanced external models like ChatGPT and Claude using MCP mode. Even when using external AIs, your files never leave the drive. Only the tiny, relevant paragraph needed for your answer is ever visible to the AI.

Everything stays securely on your USB.

How it works

Plug in. Upload. Ask.

Step 1: Plug in
Plug your PAI into any Windows, Mac, or Linux computer. No installation. No account. No configuration. Double-click app icon to start.
Step 2: Upload your documents
Drag and drop your files. PAI extracts text, images, tables, understands the structure, and indexes everything locally. A 10-page contract takes about 30 seconds.
Step 3: Connect to your preferred AI
Switch to MCP mode and configure 3rd party access. PAI sends only the relevant excerpt to your AI — not the whole document. You save more than 50% of tokens.
Step 4: Ask anything
Type a question in plain language. PAI finds the right passage, cites the source, and gives you a precise answer. No hallucination about your files.
Features

Built for professionals who work with documents.

Private by design

Your files are indexed on the USB drive. They never reach any server — ours or anyone else's. Unplug the drive and everything disappears.

Works with any AI

Connect Claude, ChatGPT etc. to your data using MCP. PAI sends only the relevant excerpt, not the full document. Most users cut their AI costs by more than 50%.

Offline, always

The drive includes a local AI model that works without internet. In a meeting room, on a plane, in a location with no signal — PAI still answers your questions.

Precise citations

Every answer includes the exact source: document name, page number, and the retrieved passage. You can verify every claim in seconds.

Excel and structured data

Upload spreadsheets alongside documents. Ask calculation questions — totals, averages, filters — and get exact answers from your own data, not approximations.
