## 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
