“Which customer segments have the highest contraction rate?”
Identifying segments with high contraction helps businesses target churn prevention strategies to stabilize revenue. This replaces complex MySQL logic involving DATEDIFF and DATE_FORMAT to isolate specific time windows and group customers by segment.

“How does the NRR of this year compare to last year?”
Comparing annual NRR allows leadership to track long-term growth trends and the health of the customer base. It eliminates the need for manual year-over-year calculations using DATEDIFF and DATE_FORMAT to filter and compare distinct calendar years.

“What is the total expansion revenue generated this month?”
Tracking expansion revenue reveals the success of upselling and cross-selling efforts within the existing user base. It removes the complexity of using DATE_FORMAT and DATEDIFF to calculate revenue deltas for the current month versus the previous period.

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 MySQL 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 MySQL database?
Yes — connections are read-only by default, so nothing can be modified or deleted. For extra safety, create a dedicated user with SELECT-only privileges or connect a read replica.
How do you handle non-standard date formats in WordPress-style schemas?
The AI uses DATE_FORMAT and STR_TO_DATE to normalize inconsistent date strings into a standard format for NRR calculation.
