Why Self-Host Instead of NotebookLM?

• Data ownership. Your data stays on your server, not on NotebookLM’s infrastructure.
• Predictable costs. Pay a fixed VPS cost instead of growing per-user or per-usage fees.
• No vendor lock-in. Export and migrate your data anytime. You control the database.
• GDPR and compliance. Hosting your own tools simplifies data residency and compliance requirements.
