Hey, I'm the author of GeoSQL. Found this thread after realizing the repo got 400 stars last week. Ask me anything.
In the example in your video are any special GEOMETRY functions being used in the underlying SQL? Or, could your data just have been in plain postgres?
A similar product GeoSQL is Malloy which puts a semantic layer on top of your data for better LLM understanding. Malloyyo gives you an MCP server for precise and auditable interaction with your data.
