The problem it answers
Every company has data and almost nobody who can query it. The people with questions do not write SQL, and the people who write SQL have a backlog. The result is that most decisions are made on the last number someone happened to see.
What we built
Talk to Your Data is a chat interface and embeddable widget that sits on top of a company's database and answers questions in plain language. Under the hood it is not "send the schema to a model and hope": queries are planned, validated against the real schema, executed with guardrails, and the answer comes back with the query that produced it, so a technical person can always verify the work.
The hard parts
The hard problem is trust, not SQL generation. We spent most of the engineering on the failure paths: what happens when the question is ambiguous, when the query would scan a huge table, when the model is confident and wrong. The system prefers asking a clarifying question over guessing, and it shows its working every time.
