SheetAI vs Numerous.ai
Numerous.ai does one thing well: an =AI function you drag down a column in Sheets or Excel. SheetAI does that too, and then keeps going - a real spreadsheet with twenty templates that already calculate, sharing, and an assistant that reworks the whole sheet rather than one cell at a time. Same starting price band, considerably more product.

The short version
If all you will ever want is one instruction applied down a column, Numerous.ai is a perfectly respectable, inexpensive way to get it. But you are buying a function, not a spreadsheet: the file, the structure and the formulas stay your job. SheetAI puts the same kind of functions in Google Sheets and Excel and adds the thing you were going to need anyway - a workbook you can actually work in. For most people that makes it the better value, even at a similar monthly price.
What each one actually is
Most of the decision comes down to this, and a feature table can hide it.
A spreadsheet application with an AI agent built into it, and a Google Sheets add-on carrying twelve functions and a chat sidebar into sheets you already have. One sign-in and one balance cover both. You get the grid, the templates and sharing in the same subscription as the AI, rather than paying for a spreadsheet somewhere else and then adding a function to it.
An add-on for Google Sheets and Excel built around an =AI function, plus tooling for bulk runs, formula generation and the usual column jobs: summarise, rewrite, extract, classify, clean. No API keys to manage. Usage is measured in characters rather than tasks, and plans are billed annually. What it is not is a spreadsheet - it improves a file you keep in Google or Microsoft.
Head to head
Shaded cell is the one we think wins that row, including the rows where it isn’t us.
| SheetAI | Numerous.ai | |
|---|---|---|
| What you're buying | A spreadsheet app and a Google Sheets add-on, on one account | An add-on only; the spreadsheet stays something you keep elsewhere |
| A workbook of your own | Yes - a real grid with formulas, charts, imports and exports | No |
| Ready-made templates | 20 built-in workbooks with formulas, formats and conditional rules already wired - budget, invoice, CRM, timesheet, KPI dashboard | None |
| Beyond filling cells | Ask for a summary block, a chart, a re-layout, a fix to a broken formula - the agent reads and edits the whole sheet | Column-shaped work: a function per cell, plus bulk runs and formula generation |
| History and sharing | Per-sheet sharing and public links, plus every AI edit listed cell by cell and undoable | Only what Google or Microsoft gives the underlying file |
| Account you need | Any email address. No Google or Microsoft account required | A Google or Microsoft account, since it runs inside their apps |
| Functions in the sheet | =SHEETAI plus ten task functions: AI_CLASSIFY, AI_EXTRACT, AI_FILL, AI_FORMAT, AI_FORMULA, AI_LIST, AI_SENTIMENT, AI_SUMMARIZE, AI_TAG, AI_TRANSLATE | =AI and companions, covering much the same jobs |
| Setup | Sign in and go; no keys, no provider account | Install and go; no API keys either |
| Entry price | Free to start with 10 credits, then $20 a month for 1,000 credits | Free week for $1, then plans billed annually from around $10 a month |
| Works inside Excel | Yes: a chat task pane and 12 AI formulas in cells (=SHEETAI.AI_ASK, AI_SUMMARIZE, AI_CLASSIFY and more) | Yes, with AI functions in cells |
| How usage is counted | Credits per turn of work, published per plan | Characters in and out - 500,000 on the entry plan - which suits long, repetitive text runs |
| Unused allowance | A plan's allowance is monthly and doesn't carry over | Their page says you keep remaining tokens after cancelling |

Their allowances are quoted in characters and ours in credits, so the columns are not one scale - and their published plan prices are annual-billing figures that have moved more than once, which is why the ranges above are hedged and linked rather than stated to the cent. Check their pricing page for today's numbers. The comparison that matters is what a month of your own work costs; both are free to try first.
Choose Numerous.ai if…
Their Excel add-in is in Microsoft's store. Ours is added with a small file from sheetai.co, or deployed to a whole organisation by a Microsoft 365 admin - a few minutes, but not one click.
If the job is rewriting product descriptions or classifying rows, month after month, and you already have the spreadsheet you need, then a function is the whole product and you should buy the cheap function.
Long repetitive text jobs are easy to predict when usage is measured in characters. Our credits are priced per turn of work, which is simpler for mixed work and less exact for bulk text.
Choose SheetAI if…
One subscription gets you the grid, the formulas, charts, imports and exports, plus the Google Sheets add-on. With Numerous.ai you are still paying for a spreadsheet somewhere else and bolting an AI function onto it.
Twenty templates ship with SheetAI - budget tracker, invoice, CRM pipeline, timesheet, KPI dashboard, attendance register - built as real workbooks, not prompts. Open one, type over the sample rows, and it calculates.
"Summarise these totals into a block at the top, chart the trend, and flag the lines that moved" is not a function call. It is a conversation with something that can read the whole grid and edit it - in the app or in the Sheets sidebar.
Per-sheet sharing, public links and undo for every AI edit come with the sheet rather than with whatever product happens to host your file.
SheetAI runs in a browser and signs in with any email address. An add-on, by definition, needs the suite it plugs into.
Moving across from Numerous.ai
Both are add-ons in Google Sheets, so there is nothing to export. You can keep both installed while you make up your mind.
- 1Install the SheetAI add-on from the Google Workspace Marketplace and sign in with any email address.
- 2Take a copy of a sheet you use often, replace one =AI() call with =SHEETAI(), and read the two columns side by side on your own data.
- 3Where you were describing a task in a prompt, try the named function instead - AI_CLASSIFY, AI_EXTRACT, AI_SUMMARIZE, AI_TRANSLATE - and see whether the output holds up better.
- 4Open the SheetAI app and import the workbook as .xlsx if you want templates and the full agent on it.
- 5Cancel the other subscription only once a full cycle of your own work has run through ours. There is no rush and no lock-in either way.
Both tools leave values in cells, so nothing breaks when you stop paying for one. The part that does not transfer is prompt tuning: a prompt shaped for one product deserves a fresh look before you trust it across thousands of rows in the other.

More comparisons
The same honest format, against the other tools people weigh up.
A capable add-on for very large batch jobs - but it is only an add-on. You still need a spreadsheet, and it isn't one.
Already inside Sheets if your company pays for Workspace. Helpful at the edges, but there is no formula to drag down a column.
The obvious choice if your company is all-in on Microsoft and will pay for it. It is a licence on top of a licence, and it stops at Excel.
A polished spreadsheet built around live data connectors. Strong if your numbers come from APIs; it does not reach into Google Sheets, and AI tasks are metered tightly on the cheap plans.
A heavyweight AI spreadsheet with Python, SQL and huge file support. Priced per seat at $29, and it only works inside Sourcetable.
Upload a file, ask questions, get charts and answers back. Good at analysis; you do not get a spreadsheet you can keep working in.
Brilliant general assistant, and it will analyse a file you upload. It is not connected to your spreadsheet, and copy-paste is not a workflow.
