ADS has IntelliSense and autocomplete. AI2SQL generates complete queries from natural language — not word completion, whole-query generation.
ADS is optimized for SQL Server / Synapse / Azure SQL. AI2SQL treats Postgres, MySQL, BigQuery, Snowflake as first-class citizens.
Ask "monthly revenue by region for Q1" — get working SQL. ADS still requires you to write the query yourself.
Different value prop — AI2SQL adds AI generation ADS lacks. Try AI2SQL free for 7 days — no credit card required.

Different tools. Copilot completes code word-by-word based on file context; AI2SQL generates full queries from a description, aware of your full database schema. For SQL specifically, schema-aware AI2SQL produces more correct queries than general-purpose Copilot.
Yes — SQL Server 2016+, Azure SQL Database, and Synapse. AI2SQL generates T-SQL dialect correctly (TOP, ISNULL, DATEADD/DATEDIFF, etc.) and understands SQL Server-specific features.
ADS is a SQL editor — you write queries. AI2SQL is an SQL generator — it writes queries for you. If you value time saved on writing complex JOINs, CTEs, and window functions, $9 pays back in a few hours of work saved per month.
Yes. Both Synapse (dedicated pools and serverless) and Azure SQL Database are supported. Connection uses standard connection strings; no Azure extensions needed.
Not yet — AI2SQL focuses on single-query generation with history. If you lean heavily on notebooks for reproducible analysis, ADS notebooks or Hex are stronger. For fast iterative query writing, AI2SQL is faster.
