Quadratic

Overview

Quadratic is a spreadsheet for people who need more than formulas, bringing Python, SQL, JavaScript, live data connections, and AI-assisted analysis into one workspace. It is best suited to data-minded individuals and teams who want to inspect and edit generated work rather than accept a finished answer at face value. Its breadth is compelling, but plan limits and the annual commitment for paid tiers deserve a close look.

Users can ask questions in plain English and have AI create formulas, code, or charts. The output stays in spreadsheet cells, where it can be reviewed and changed—a useful distinction for analysis that needs follow-up or correction. Quadratic says one sheet can support 100 million rows and that it can import multi-GB CSV and Parquet files, making it a candidate for datasets that would strain a conventional workbook.

It imports CSV, Excel/XLSX, Parquet, PDF, and Google Sheets, and exports Excel/XLSX, CSV, Quadratic/Grid, PNG, and PDF. The connections directory includes PostgreSQL, Snowflake, BigQuery, QuickBooks, Google Analytics, Mixpanel, Plaid, and Salesforce. Its MCP server lets compatible AI tools read sheets, write cells and charts, and run Python, SQL, and formulas; the API can trigger AI runs and read or write cells.

Key features

• AI with editable output: Plain-English requests can produce formulas, code, and charts. Keeping results in cells makes it easier to audit and refine the work than a standalone answer, though the value depends on users being willing to review that output.
• Code and connected data: Python, SQL, and JavaScript sit alongside spreadsheet formulas, while SQL connections and a broad set of named services offer routes to live data. This suits users who want analysis and source data in the same environment; it may be more capability than someone seeking a simple grid needs.
• Large-file support: The stated 100-million-row sheet capacity and multi-GB CSV and Parquet imports are notable for data-heavy work. The claim is a capacity ceiling, not a reason to assume every workflow will benefit from that scale.
• AI tool and API access: The MCP server exposes sheet editing and code execution to compatible AI tools, and the API can launch AI runs and exchange cell data. These are useful extensions for connected workflows, but less relevant to spreadsheet users who work only inside the app.
• Security and control: Quadratic says its cloud service is SOC 2 and HIPAA compliant, and that data is stored and calculations run on the user's computer by default. Business and Enterprise customers can also self-host, with AWS and Docker supported.

Pricing

Quadratic has a free Personal plan and paid tiers billed annually. Personal is aimed at individuals, but limited AI usage, sharing, files, connections, and support make it a constrained starting point rather than a full-featured team option. Its price is custom pricing.

• Personal: Custom pricing. Limited AI usage, sharing, files, connections, and support. A fit for an individual trying the workflow, provided those limits are acceptable.
• Pro: $18 a month (billed annually). It includes $20 in AI credits per month, additional privacy controls, and unlimited sharing, files, and connections. This is the clearest fit for shared-workspace users, though the annual billing matters if needs change.
• Business: $36 a month (billed annually). It includes $40 in AI credits per month, the Pro features, and the option to buy additional AI credits on demand. Teams that need more AI capacity have a defined upgrade path; the higher annual price is harder to justify for lighter use.
• Enterprise: Custom pricing, with custom AI usage, single sign-on, self-hosting, and dedicated support. It is intended for companies that need those controls and services rather than a standard individual or shared-workspace plan.

There is no free trial. Pro and Business are the published paid entry points, while Personal has limited quotas and capabilities; compare those constraints with your expected sharing, connection, and AI needs before committing annually.

Platforms

Quadratic lists Android, iOS, macOS, Windows, web, API, and self-hosted availability. Standalone desktop apps are available for macOS and Windows, and its changelog describes a mobile UI for phones. Self-hosting is offered on Business and Enterprise, not as a general substitute for the hosted entry tiers.

Who it's for

Quadratic is a strong match for people who combine spreadsheet work with code, SQL sources, or AI-assisted exploration, especially when they want to inspect and edit generated results. Pro fits users who need shared workspaces and uncapped sharing, files, and connections; Business suits teams needing more AI credits. It is less suitable for someone who wants an uncomplicated spreadsheet, has little use for code or connected data, or cannot accept annual billing for paid access.

Pros and cons

• Pro: AI output remains editable in cells, so users can inspect and refine formulas, code, and charts.
• Pro: Broad import, export, and connection options make it practical to bring data in and move results out.
• Pro: Business and Enterprise self-hosting, alongside stated cloud compliance and local-by-default processing, give organizations different control options.
• Con: Personal limits AI, sharing, files, connections, and support, which can make the free tier restrictive for sustained or collaborative work.
• Con: Pro and Business prices are billed annually, and there is no free trial to evaluate a paid tier before that commitment.
• Con: Business costs $36 a month billed annually; its extra AI capacity is valuable mainly to teams that will use it.

Verdict

Choose Quadratic if you want a spreadsheet that combines code, connected data, and AI assistance while keeping generated analysis editable. That combination is its strongest reason to choose it, especially for users who need to inspect and build on results. Look elsewhere if you need a simple spreadsheet, rely on generous free collaboration, or want to avoid an annual paid-plan commitment.
