| > **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 | |
