Defog.ai
Defog.ai answers data questions in plain English across databases, SaaS tools, and uploaded CSV files. You ask follow-up questions, drill into specifics, or explore broad hypotheses without waiting on an analyst queue. The product targets teams that need self-serve analytics on structured data with privacy controls baked in.
Most text-to-SQL tools bolt a chat box onto a generic model. Defog.ai ships SQLCoder, its own open-source model fine-tuned for structured data, and runs queries inside your environment so underlying data never leaves your servers. That privacy-first setup trades quick signup simplicity for enterprise deployment options like Docker, Slack bots, and self-hosted models.
Defog.ai fits data teams, analysts, and business users at companies with Snowflake, Postgres, or other warehouses who want GPT-4-class SQL accuracy without sending raw data to a third-party API. Enterprise cloud plans start at $5,000 per month with 20,000+ queries included.
