SheetAI is a Google Sheets add-on that embeds generative AI capabilities into spreadsheets via custom functions (for example, =SHEETAI() and specialized variants such as functions for summarization, classification, and extraction). The add-on is designed to reduce manual spreadsheet tasks (content generation, formula generation, classification, extraction, auto-fill) by enabling calls to large language model (LLM) APIs from within cells and menus, without requiring users to write code.
SheetAI is presented as supporting multiple model providers and additional API integrations for multimodal tasks, per vendor materials.
