ModelMonkey
ModelMonkey is an AI-powered spreadsheet assistant that integrates directly into Google Sheets and Microsoft Excel to help you analyze data, write and update formulas, build financial models, clean and automate workflows, and generate insights without manual formula writing or coding. You interact with your spreadsheet using plain-English commands while ModelMonkey reads your sheet’s structure, understands relationships and data flow, plans changes, shows what it will do for review, and then applies edits with explanations and one-click undo, avoiding black-box automation. It is powered by Claude Sonnet 4.5 and supports tasks like complex financial modeling (three-statement models, DCFs), trend analysis, data cleaning, integration with external data sources (including PostgreSQL), and dynamic formula generation, all with enterprise-grade encryption and zero data retention.
