Numerous.ai is an add-on that puts ChatGPT inside Google Sheets and Microsoft Excel. After installing it you call an =AI function from any cell, so a prompt can be applied down a whole column instead of being typed into a chat one row at a time. No API key has to be supplied. The site lists typical jobs: generating ad keywords, ad copy and SEO content for marketing campaigns; summarising, rewriting and extracting information from open-ended text such as survey answers or articles; sorting entries into categories; and cleaning and normalising messy input. Because results are cached for the long term and repeated queries are not sent twice, the same sheet can be shared and re-opened without paying again for identical prompts. A plan is shared by everyone on a team and works in both spreadsheet programs. The company, Numerous.ai, Inc., says its team is based in San Francisco. ## Key features - **=AI Function**: Runs a prompt from a spreadsheet cell and returns the answer in place, ready to fill down a range. - **No API Key Setup**: Works after installing the add-on, without creating or pasting keys from an AI provider. - **Sheets and Excel Support**: Covers Google Sheets and Excel under the same subscription. - **Result Caching**: Stores earlier outputs and skips duplicate queries to keep usage down. - **Text Classification and Cleaning**: Summarises, categorises, extracts and normalises free-text data in bulk. - **Team Plans**: Lets all members of a team use one plan, with email or priority support. ## Use cases - **Ad Campaign Preparation**: Generate keywords, headlines and ad copy for many products in one sheet. - **Survey Analysis**: Classify and summarise hundreds of open-ended responses. - **Data Clean-Up**: Standardise inconsistent names, addresses or labels entered by users. - **Content Calendars**: Produce topic ideas and post variants for different audiences from one prompt. - **Prompt Prototyping**: Compare prompt structures side by side and share the outputs with colleagues. ## Things to know - **Usage is measured in characters**: The plan shown on the site includes a monthly allowance of ChatGPT input and output characters per person. - **Trial is paid**: The site advertises a seven-day trial for a small fee instead of a free tier. - **Tokens kept after cancelling**: The site says you can cancel at any time and keep the remaining tokens. ## FAQs ### What is Numerous.ai?
