Quadratic

Quadratic is a next-generation intelligent spreadsheet lead-invested by GV (Google Ventures) that deeply fuses Python/SQL/JavaScript programming with the traditional grid. Unlike black-box AI tools, every AI-generated analysis appears as visible, auditable code, letting data teams keep the spreadsheet's intuitiveness while gaining the power of professional programming.

Core Capabilities

• AI natural language analysis: Ask questions in natural language to generate code, clean data, and create visualizations, powered by Claude 3.5 Sonnet and GPT-4o
• Native programming support: Write Python, SQL, or JavaScript directly in cells, with mainstream libraries like Pandas, NumPy, and Plotly
• Live database connections: Native support for PostgreSQL, MySQL, Snowflake, and BigQuery, with data sources refreshing in real time
• Infinite canvas design: A Figma-like infinitely zoomable canvas rendering large datasets smoothly at 60fps
• Real-time multiplayer collaboration: Google Docs-style synchronized editing with visible teammates' cursors and code changes, plus revertible version history
• MCP ecosystem integration: As an official MCP server, it lets AI tools like Claude, Cursor, and ChatGPT read and write spreadsheets directly

Best For Data analysts bouncing between spreadsheets and Jupyter Notebook, data engineers building reusable data pipelines, finance teams pulling live figures from QuickBooks, and cross-functional teams that need transparent, auditable collaborative analysis.

Unique Advantages Code transparency is the biggest highlight — all AI analysis is visible and editable, satisfying enterprise compliance requirements. A Rust/WebGL-based architecture far outperforms traditional spreadsheets. SOC 2 and HIPAA certified, with self-hosted deployment support.

Editor's Review Users rate it a perfect 5.0/5, and professional data scientists report it fully replaces their messy Jupyter Notebooks. Its funding pedigree and all-star investor lineup (the Pandas creator, Replit's CEO) validate the market potential. Permanently free for individuals with a strong-value team plan. For data teams that need code power and transparency, this is one of the best options on the market today.
