Frequently asked questions
Do I need to know SQL to get these answers?
No. You type the question in plain English exactly as written above, and the AI writes and runs the PostgreSQL query against your database for you. You can inspect the generated query if you want to, but you never have to write it.
Is it safe to connect my production Postgres database?
Yes — connections are read-only by default, so nothing can be modified or deleted. For extra safety, create a dedicated role with SELECT-only grants or connect a read replica.
How do you handle timestamptz and timezone offsets for accurate monthly billing?
The AI automatically normalizes all timestamps to your preferred timezone using AT TIME ZONE before applying date_trunc for monthly buckets.
