SheetAI

SheetAI is an artificial intelligence productivity extension and spreadsheet augmentation tool engineered for marketers, sales operations managers, data cleaners, and startup founders. Designed to supercharge Google Sheets with large language model capabilities, the application embeds custom AI functions directly into standard spreadsheet formulas.

The extension introduces intuitive custom functions such as SHEETAI, SHEETAI_BRAIN, and SHEETAI_IMAGE that execute inside spreadsheet cells. Users can sanitize messy address lists, generate personalized cold email copy for thousands of prospective leads, categorize open-ended survey feedback, and summarize company descriptions directly in bulk. The system accesses real-time web browsing to enrich incomplete company records with verified data.

SheetAI functions as a native Google Workspace Marketplace add-on that activates within Google Sheets on any desktop internet browser. The platform provides a free starter plan allowing initial formula executions, complemented by tiered monthly and annual subscription options that offer unlimited formula calls, customized API keys, and priority processing.
