You own the P&L
You don't have to run the query yourself.
The first step needs someone with read access to your warehouse catalog. That is a two-minute task for whoever maintains your data stack, and it does not need your involvement beyond forwarding the message below.
What you are asking for
- One read-only query against the catalog — the list of table and column names, and their types.
- No rows, no customer records, no credentials, and no connection to your database.
- The result pasted back into the browser. Nothing is stored unless you choose to save it.

Subject: Quick ask: one read-only query for a margin check
Hi — I'm looking at whether we can see gross margin per customer, including what inference actually costs us to serve each one. There's a tool called NemulAI that answers this from metadata first, before any data leaves us. The first step is a single read-only query against the catalog (information_schema or equivalent) — it returns table names, column names and column types. No rows, no customer records, no credentials, and nothing connects to our database. Could you run it and paste the result back? It generates the query for whichever warehouse we use, and it takes a couple of minutes: https://www.nemulai.com/audit/new The first two steps are free and don't need an account, so we'll know whether our data can even answer the question before we commit to anything. Here's what the finished output looks like: https://www.nemulai.com/sample Thanks.
What comes back
Margin per customer, worst first — what each account pays you against what it costs to serve. Including, plainly, the cost that could not be attributed to any customer and what would have to change to attribute it.
