Fabi.ai combines SQL and Python in AI-native “Smartbooks”—next-generation Jupyter notebooks with reactive cells and AI assistance. Free tier includes 15 AI requests/day; Individual at $39/seat/month; Team at $199/month (4 builders). The platform enables seamless switching between SQL queries and Python analysis in the same document with reactive updates—changing a query automatically re-runs dependent Python cells. AI assistant generates SQL from natural language, explains queries, suggests optimizations, and writes Python visualization code. Connects to Snowflake, Redshift, BigQuery, PostgreSQL, and Google Sheets. Features include version control, scheduled execution, sharing with stakeholders, and dashboard creation from notebook outputs. The reactive cell model eliminates manual execution ordering issues common in traditional notebooks. Best suited for analysts who combine SQL data retrieval with Python analysis and want AI assistance throughout workflow.
