r/bigquery

Hi all,

Has anyone found a decent open source tool for asking questions in plain English on top of BigQuery? Something self hosted.

I tried Gemini in BigQuery and had a look at the conversational analytics API. The API gives you back SQL and a chart spec, so you still end up building the front end yourself, which is the part I was hoping to avoid.

My main worry is the numbers. If two people ask for revenue in slightly different words I'd like them to get the same answer, and I don't see how that works unless the metrics are defined somewhere.

The other thing is cost. I have no feel for how many queries a single question turns into once the model starts looking around the schema.
