About Defog.ai
Defog.ai is an enterprise AI data analyst that lets business teams ask questions about their data in plain English and get answers back as SQL, tables, and charts—without waiting on an analyst. It connects to structured databases (Postgres to Snowflake) or plain CSVs, fine-tunes on a company's metadata for accuracy, and keeps data private (never shared with the AI model), making it a fit for regulated, data-sensitive enterprises. Its key differentiator is SQLCoder, Defog's own open-source, industry-leading text-to-SQL model that rivals GPT-4-level accuracy on specialized SQL tasks.
