Quadratic vs SheetAI

Quadratic is an AI-enabled spreadsheet that combines spreadsheet formulas with Python, SQL, JavaScript, live data connections and AI. Users can ask questions in plain English, then inspect and edit the formulas, code and charts AI generates in spreadsheet cells. It imports CSV, Excel, Parquet, PDF and Google Sheets files, and connects to sources including PostgreSQL, Snowflake, BigQuery, QuickBooks, Google Analytics, Mixpanel, Plaid and Salesforce. Quadratic says a sheet can hold 100 million rows and can import multi-GB CSV and Parquet files. Its MCP server lets compatible AI tools read sheets, write cells and charts, and run Python, SQL and formulas; an API can trigger AI runs and read or write cells. Quadratic says data is stored and calculations run on the user's computer by default, and that its cloud service is SOC 2 and HIPAA compliant. Desktop apps are available for macOS and Windows, with a mobile UI for phones. Personal is free with limits; Pro costs $18.00 per month, billed annually.

SheetAI is a Google Sheets add-on that runs AI formulas and media generation inside spreadsheets. It supports formula generation, table transformation, spreadsheet analysis, workflow automation, custom functions, and API access. Keys can connect OpenAI, Claude, Gemini, Grok, or Replicate; Replicate enables bulk image, video, and music generation. Filling a formula down a column can turn one prompt into hundreds of output rows. Installation comes through Google Workspace Marketplace and opens inside an existing Sheet. The free BYOK tier uses your own provider key, gives unlimited SHEETAI calls and formula generation, and sends provider charges directly to you. Starter costs $12 a month and includes approximately 500 AI runs monthly. Pro costs $29 a month, while Pro Yearly costs $290 a year; both describe higher, soft-unlimited usage. Credit packs range from $29 a month to $299, paid once. Licenses follow a Google Account email. The company says it does not view or share customer data and saves only essential information.
