Why We Make Database Connections Free
Live database querying doesn't use our storage or embedding infrastructure, so we can offer it completely free.
Our Business Model
We charge for document storage
When you upload PDFs, CSVs, or other files, we store and process them. That's where our costs are.
Database queries use your resources
Live database connections query your database directly. No storage or processing costs for us.
More value for everyone
Free database connections make our platform more valuable, leading to more document uploads over time.

API DocumentationFrequently Asked Questions
Is live database querying really free?
Yes! Connecting your database and running AI queries is completely free for all API users. No credit card required, no hidden fees. We only charge for document storage ($10/GB), not for live database connections.
What databases can I connect?
We support PostgreSQL, MySQL, and SQL Server. You can connect via direct connection or secure SSH tunnel for enterprise security.
How secure is my database connection?
Very secure. We recommend SSH tunnel connections which keep your database completely private. All connections use read-only credentials that you control, and we never store your database data.
Do you store my database data?
No! We only store a lightweight schema index (table names, column types) to help the AI understand your database structure. Your actual data stays in your database and we query it in real-time.
What kind of questions can I ask my database?
Ask anything in natural language: 'How many users signed up last month?', 'What's our top selling product?', 'Show me revenue by region'. The AI converts your questions into SQL and executes them against your live data.
Are there any limits on the free tier?
The free tier includes live database connections with no query limits. You can connect one database per knowledge base. For multiple databases or advanced features, upgrade to our paid plan.
