What is Quadratic?
Quadratic is an AI spreadsheet that connects to your data and lets you analyze it with plain-English prompts, Python, SQL and formulas. It is made by Quadratic, a US startup that builds its spreadsheet as a browser app with an open-source core. Each cell can hold a value, a formula or code, and Python, SQL and JavaScript run directly in the grid.
What makes Quadratic different from Excel or Google Sheets is that code and live data are first-class. You can connect databases such as PostgreSQL, MySQL and Snowflake or apps such as QuickBooks and Google Analytics, query them with SQL, then ask the AI to build charts, clean data or write Python. It can also extract tables from PDFs and run scheduled automations. Analysts, finance teams and engineers use it for reporting, dashboards, data cleaning and quick models.
