RAG Document Assistant

Search your documents with AI. Your data stays yours.

The Problem

Organizations need AI-powered document search but face a critical barrier: data privacy.

Traditional solutions require uploading sensitive documents to third-party servers, creating:

• Compliance risks (GDPR, HIPAA, SOX)
• Data breach exposure
• Loss of control over proprietary information

Our Solution: Zero-Storage Architecture

Your documents stay in YOUR cloud storage. Always.

Zero-Storage Guarantee

What Happens	Where	Stored?
File reading	Your browser	No
Text chunking	Your browser	No
Original text	Never	No
Embeddings	Server	Yes (irreversible)
File paths + positions	Server	Yes (for re-fetch)
Text at query time	Re-fetched from YOUR Dropbox	No

Why this matters: Your document content is NEVER stored on our servers. At query time, we use the file paths and positions to re-fetch the exact text from YOUR Dropbox. Disconnect Dropbox = queries stop working = complete data control.

---

Why This Matters

For Compliance Teams

• No data leaves user devices = No data breach risk
• Embeddings are not personal data = GDPR-friendly
• Audit-ready architecture

For Security Teams

• Zero attack surface on document content
• No sensitive data in transit or at rest
• Client-side processing eliminates server vulnerabilities

For Business Leaders

• Use AI document search without compliance reviews
• No vendor lock-in on your data
• Deploy with confidence

---

How It Works

1. Connect Dropbox - OAuth authentication (we never see credentials)
2. Select Files - Choose .txt, .md, or .pdf files (up to 5 MB)
3. Index - Text processed in your browser, only embeddings sent to server
4. Search - Ask questions in natural language
5. Get Answers - Receive cited responses from your indexed content

Use Cases

• Compliance: Search regulatory documents without data exposure
• Legal: Query contracts while maintaining privilege
• HR: Access policy documents securely
• Research: Search proprietary research without leakage
