See It in Action

Real screenshots of the add-on working inside Google Sheets™, from a one-line prompt to a finished forecast tab.

SheetAI's Act mode building a revenue dashboard in Google Sheets from one sentence: ARR, net new MRR and growth % columns added and formatted, with the agent's checklist and tool activity in the sidebar.
SheetAI's Ask mode answering which months drove the most growth, in plain language, without changing a single cell in the spreadsheet.
SheetAI's Plan mode proposing a 2027 forecast plan with Approve & run, Edit and Cancel buttons, before it touches the sheet.
The Forecast tab SheetAI built after a single approval: 2027 MRR best, base and worst case scenarios, linked assumptions, live formulas and a line chart.
The =AI_SENTIMENT and =AI_CLASSIFY custom functions filled down a column of customer feedback in Google Sheets, with SheetAI's function reference open in the sidebar.

Everything You Need

A complete AI toolkit that lives inside your spreadsheets.

AI Custom Functions

Type formulas like =SHEETAI("summarize this") directly in your cells. 12 specialized functions for classification, extraction, translation, sentiment analysis, and more.

Intelligent Chat Sidebar

Ask questions about your data, generate formulas, create charts, and automate tasks through natural language, all without leaving Google Sheets™.

Smart Data Analysis

Get instant insights, detect patterns, find outliers, and run statistical analysis on your data with a single prompt.

Automated Data Cleaning

Remove duplicates, fix formatting, standardize entries, and clean messy data automatically using AI.

Adjustable Thinking Depth

Dial the AI's reasoning up for complex analysis or down for fast edits. Control the speed-vs-depth tradeoff right from the sidebar.

Connected Apps, Skills and @ Mentions

Apps you connect on sheetai.co (Notion, HubSpot, Stripe, Airtable, Jira and more) are available in the sidebar, so the AI can pull their data into your Sheet. Type / to run a skill such as /analyze or /clean, and @ to point at a tab or a connected app.

Works with Collaboration

The add-on runs inside Google Sheets™, so Google's own sharing and co-editing are untouched. Each collaborator who wants to use the AI signs in to their own SheetAI account.
