Spreadsheet add-on that adds an =AI formula to Google Sheets, billed annually with character caps. Excel is listed only on the team plan card.
People who want AI as a spreadsheet formula rather than a separate app, since Numerous publishes an "=AI" function usable in any cell along with =WRITE and =INFER, and handles the model account itself so no API keys are required. It fits repetitive text work on rows - the site names summarising, rewriting, extracting, classifying and cleaning text, and generating ad copy, keywords and SEO content - and caches responses in its database to avoid duplicate queries on refresh. Teams of up to eight people are catered for by one plan at a published per-team price.
Excel-first buyers should check the plan card before assuming coverage: the homepage advertises use "inside Google Sheets and Excel", but the pricing page lists "Use in both Google Sheets and Excel" only under the Enterprise team plan, and the Personal and Pro cards do not list Excel at all. There is no free tier and no monthly option on the published cards - every plan is "Billed annually" with "First 7 days free", while the homepage instead advertises a 7-day trial for $1. Buyers who need a vendor statement that their own model training is excluded will not find one: Numerous only quotes OpenAI's position that data submitted through their API is not used for training, and states it caches responses in its own database.
Pros
Cons
The homepage says it works inside both, but the plan detail is narrower: the pricing page lists "Use in both Google Sheets and Excel" only on the Enterprise team plan, and the Personal and Pro cards do not list Excel. Excel use is through an Office add-in - numerous.ai/excel redirects to the Microsoft Office store install page - while Sheets uses an add-on you set up first.
No free tier is published. Every plan card reads "$10 / month", "Billed annually", with "First 7 days free", and the page advertises saving 57% with yearly billing. The homepage advertises the trial differently, as 7 days for $1. The page states you can cancel anytime and keep your remaining tokens forever, so unused allowance is not forfeited on cancellation.
Personal and Pro both publish 1,000 tokens, 500,000 characters of ChatGPT inputs and outputs, and 500 formula generations. The Enterprise team plan publishes 1 million characters of inputs and outputs per person for up to 8 users and lists no token or formula-generation cap. No overage rate is published for exceeding these limits. Cached responses avoid duplicate queries when a sheet refreshes.
Numerous states each request is transferred to its AI partner OpenAI via their API, and cites OpenAI's position that data submitted through the API is not used to train their models and is retained 30 days for abuse and misuse monitoring. Numerous stores formula data on Google Cloud in the United States, caches responses in its own database, and says it stores nothing not explicitly passed into =AI, =WRITE or =INFER.
