NLSQL

NLSQL is a natural-language analytics product that converts plain-English questions into SQL queries against company databases and returns answers and charts in seconds. It is installed from the Microsoft Azure Marketplace into the customer's own Azure subscription and can be used as a bot in Microsoft Teams, in web chat or as a standalone web app, with Slack also mentioned. Administrators map their database structure and define business intents in a self-service platform, after which employees can ask questions without writing SQL. Listed data sources include SQL Server, PostgreSQL, SAP HANA, Snowflake, Redshift, MySQL and Supabase. The company also offers related products, including an AI agent for unstructured knowledge bases and an AI employee for reporting tasks, some of which are available on AWS Marketplace.

The product targets companies whose staff need quick access to data without relying on analysts. Generated queries and numbers should still be validated for important decisions, and nothing was tested for this listing.

The homepage offers a free 30-day trial without a credit card. Paid pricing is handled through the Azure and AWS marketplace listings, which were not reviewed here, so check the marketplace for current costs.

NLSQL states that the bot runs inside the customer's Azure tenant and that no sensitive data leaves the customer's IT environment; this is a vendor statement that was not independently verified. Its terms of use, last updated in April 2026, apply to both the website and NLSQL products distributed through Microsoft marketplaces or directly.
