Quadratic

Quadratic is an AI-powered spreadsheet that lets you use code alongside normal formulas. You can run Python, SQL, and JavaScript right inside cells to analyze data, build dashboards, and automate work. It connects to databases, APIs, and files like CSV and Excel, and its AI assistant writes code from plain-language questions. Data analysts, finance teams, and developers use it for deeper analysis than normal spreadsheets allow. It runs in the browser with no install, and teams can edit sheets together in real time.

Key Features

1. Code in Cells

Write Python, SQL, or JavaScript directly in cells. Code runs next to normal formulas, and results flow back into the grid.

2. AI Assistant

Ask questions in plain language and Quadratic AI writes the code or builds the chart. You can edit every line it generates.

3. Live Data Connections

Connect to databases like PostgreSQL, MySQL, Snowflake, and BigQuery. Query millions of rows without exporting CSV files.

4. Real-Time Collaboration

Teams edit the same sheet at the same time. Everyone sees changes instantly, like multiplayer editing in a document.

5. Charts and Dashboards

Build charts from your data with AI or Python libraries like Plotly. Charts update automatically when the data changes.

6. Runs in the Browser

Built on Rust and WebAssembly, so it handles large datasets fast. No install or environment setup is required.
