How PrivDF Works

Five simple steps to private PDF analysis

1️⃣

Upload Your PDF

Drag and drop any PDF file. It stays in your browser's memory—we never send it to our servers.

2️⃣

Set a Passphrase

Choose a password to encrypt your annotations. This passphrase never leaves your device.

3️⃣

Highlight & Annotate

Select text to create highlights or add notes. Everything is encrypted with AES-GCM before storing locally.

4️⃣

Analyze with AI

Click "AI Tools" to summarize or ask questions. We send only the text (not the PDF) to Venice AI for analysis.

5️⃣

Export or Delete

Export your annotations as an encrypted ZIP file, or delete everything with one click.

🔄

Import Anywhere

Import your exported ZIP file on any device to restore your annotations and continue working.

Privacy-First Architecture

PrivDF uses modern browser APIs (Web Crypto, IndexedDB, PDF.js) to process everything locally. When you use AI features, only extracted text chunks are sent to Venice AI—never your original PDF. Venice AI doesn't retain your data, and you control your API key.
