What is Numerous.ai?
Numerous.ai is an AI add-on for Google Sheets and Excel that lets you use ChatGPT inside cells with a formula: type =AI with your instruction and the sheet returns the result row by row. It's designed for working with AI at volume without coding or managing API keys, and the team is based in San Francisco.
What is Numerous.ai used for?
It turns a spreadsheet into a way to run ChatGPT at scale. With one instruction you can summarize, rewrite or extract data from long text, sort survey answers or social comments into categories, and clean or normalize messy input. It also produces content ideas, ad keywords, campaign copy and post variations from a column of data.
How does Numerous.ai work in Sheets and Excel?
You install the add-on and use its functions like any other formula. Besides =AI, the site highlights =INFER, which learns from examples you've already filled in to complete the remaining rows, and a generator that writes complex formulas from a plain-English description. Numerous.ai caches results to avoid paying for duplicate queries and lets the whole team share the same account.

Numerous.ai pros and cons
Pros: no OpenAI keys needed, it works in both Google Sheets and Excel, and it uses the sheet's structure to process hundreds of rows with one prompt. Cons: usage is capped by an allowance of input and output characters, and outputs still need checking, since they depend on the quality of the instruction like any language model.
