Quadratic

What is Quadratic?

Quadratic is a browser-based spreadsheet with an AI assistant that analyzes data, writes formulas, code and charts from questions in plain English. You can run Python, JavaScript and SQL directly in cells alongside normal formulas, and open any generated cell to check or edit what the AI produced. It pulls in CSV, Excel and PDF files and connects to databases, data warehouses and services such as QuickBooks, Google Analytics and Plaid. Sheets can hold up to 100 million rows, and multiple people can edit at once with cursors and version history. Quadratic also supports the Model Context Protocol, so agents such as Claude, Cursor and ChatGPT can work in a live sheet, and it offers an API for reading and writing cells. It suits analysts, finance teams, founders and students. The Personal plan is free with limited AI usage, Pro is $18 per user per month billed annually, Business is $36, and Enterprise is custom.
