Defog.ai

AI data analyst built on Defog's own fine-tuned text-to-SQL model, SQLCoder, for querying warehouses and uploaded CSVs.

Visit Defog.ai Alternatives

Defog.ai offers an AI data-analyst product built around SQLCoder, a text-to-SQL model the company fine-tuned and open-sourced. Users connect a database (Postgres, Snowflake, and others) or upload a CSV, then ask follow-up questions in plain English; the model converts each question into SQL run against that data. As with any text-to-SQL system, result quality depends on how well the schema is described to the model. Defog states customer data is not shared back into training its models. The company does not publish self-serve pricing or plan tiers on its site and appears to sell primarily through direct contact rather than a self-serve signup, so it should be evaluated as an enterprise/contact-sales product rather than a subscription tool.
