IDERA AI SQL Query Generator vs NatureQuery

IDERA AI SQL Query Generator is a free web tool that turns plain-English questions into SQL drafts. Users can enter table and column names to provide schema context, then ask what they want to query. The AI model generates SQL that can be copied, edited, or regenerated before the user runs it in a separate database. The tool does not connect to or execute queries against that database. No installation is required, but a modern browser and internet connection are needed. IDERA says limits apply to keep the free tool available, without stating their values on the product page. Prompts and outputs may be logged anonymously for quality, while supplied details are not retained long term. IDERA describes the generator as a way to make SQL querying more accessible and reduce the learning curve for teams. Help is available through community forums and an email contact.

NatureQuery turns natural-language questions into SQL, runs them against a connected database, and exports results as Excel spreadsheets or CSV files. Its AI is described as understanding database schemas, and the product can create bar, line, and pie charts from results. Listed database support includes PostgreSQL, MySQL, SQLite, SQL Server, MariaDB, and Amazon Redshift. Teams can invite members and share connections and saved queries using role-based access. The cloud service is available through the web and API. Its free plan costs nothing and includes 50 queries per month, one database connection, and 30 days of query history. Pro costs $20 a month and includes unlimited queries, 10 connections, collaboration for five members, API access, and priority support. Enterprise costs $79 a month and lists unlimited queries, connections, and members, plus SSO / SAML, audit logs and compliance, and dedicated support with an SLA. NatureQuery says credentials and connections are encrypted and query results are not stored.
