TL;DR: I built a free, open-source SSMS 21 & 22 extension that plugs a locally-hosted 7B model (served by LM Studio) straight into SQL Server Management Studio. Your schemas, your queries and your data never leave your machine — and the monthly bill is exactly $0. Repo at the end. 👇

The problem: I wanted AI in my IDE, not in someone's cloud

AI assistants for SQL are genuinely useful. They write your JOINs, they explain execution plans, they review stored procedures. But every single one of them ships your context to a remote API: your table names, your column names, sometimes data samples — all landing in somebody else's logs.

In a lot of real environments that's a hard no : regulated data, strict corporate rules, air-gapped servers. And in some parts of the world, international payments for API subscriptions are a whole separate problem of their own.

Meanwhile, a 7B model running on my own GPU is already good at T-SQL. It doesn't need Azure. It doesn't need OpenAI.…
