First up is TEXT2SQL. This AI-powered tool converts natural language text into SQL queries and supports several SQL dialects, including MySQL, PostgreSQL and Snowflake. TEXT2SQL not only writes SQL queries, but also explains them in plain English and corrects query errors. It works with custom database schema and offers API access and priority support with its annual plan. You can try it with a 7-day free trial before you pay.
Another good option is Avanty, a Chrome extension geared specifically for data analysts using Metabase. Avanty uses AI to help write, edit and understand SQL queries. It writes SQL from natural language prompts, edits SQL automatically and debugs errors. It also deconstructs queries, explains them and formats SQL. There's a 14-day free trial and several pricing tiers, including an Early Access plan for $19 per month.
