Overview

Numerous.ai is an add-on for Google Sheets and an add-in for Excel that runs ChatGPT through spreadsheet functions such as =AI, =INFER and =WRITE. It is aimed at marketers, researchers and other people who work through long lists of text in a spreadsheet. A function is dragged down a column to summarize, categorize or rewrite each row. It is sold as a subscription billed monthly or yearly, with the first 7 days free.

Our take

Pick it if the work is a column of text that needs the same treatment row after row, such as tagging survey answers or drafting ad copy, and you want to stay inside the sheet you already use. If you need charts, dashboards or a written analysis of a whole dataset, it is the wrong tool: it answers one cell at a time. The Personal plan is limited to a single user, so a team sharing prompts should look at Pro or the per-seat Enterprise plan.
