The safety valve is the point: you type the question in plain English, Widen writes the SQL, and nothing executes until you have looked at it. A native Mac app rather than an Electron shell, with no backend and no account — on macOS 26 it can run the text-to-SQL step on-device, so the schema never leaves the machine. Postgres only, MIT-licensed, and honest enough to label the text-to-SQL as beta.
