SheetAI vs Sourcetable
Sourcetable is the more technical product: a standalone AI spreadsheet with a Python and SQL toolkit, data connectors and very large file support, at $29 per seat a month. SheetAI is the more practical one for most spreadsheet work: $20 a month, twelve AI functions you can fill down a column, twenty templates that already calculate, and the Google Sheets add-on included so your existing files come along.

The short version
Sourcetable is aimed at people who would otherwise open a notebook - it puts Python, SQL and a data-science toolkit next to the grid, and it will swallow files far larger than a browser spreadsheet has any right to. If that is your job, buy it. For the far more common job - building, cleaning and reworking business spreadsheets, and doing it in the files your team already has - SheetAI costs less, includes the Google Sheets add-on that Sourcetable has no equivalent for, and gives you AI as formulas rather than only as a chat. Their free tier is more generous than ours; almost everything else points our way.
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 in it, plus a Google Sheets add-on carrying twelve functions and a chat sidebar into sheets you already have, and an Excel add-in with the same chat. One sign-in, one balance, everywhere. Twenty templates ship as finished workbooks; .xlsx and .csv import and export cleanly; every AI edit can be reviewed and undone.
A standalone AI spreadsheet: Excel-like formulas plus an assistant, data connectors to databases and applications, a Python and SQL toolkit, and support for files up to 10GB. Usage is metered in credits - 50 a month free, 2,000 on the $29 seat, 6,000 on the $100 seat - with top-up credits sold at a couple of cents each. It is not an add-on: your work lives in Sourcetable.
Head to head
Shaded cell is the one we think wins that row, including the rows where it isn’t us.
| SheetAI | Sourcetable | |
|---|---|---|
| Works inside Google Sheets | Yes - functions and a chat sidebar, included on every plan | No. Your work lives in their product |
| AI you can put in a cell | Twelve functions filled down like formulas: AI_CLASSIFY, AI_EXTRACT, AI_TRANSLATE, AI_SUMMARIZE, AI_SENTIMENT and more | An assistant beside the grid, with autofill and cleaning features |
| Price to get started properly | $20 a month for 1,000 credits | $29 per user a month for 2,000 credits |
| Ready-made templates | 20 built-in workbooks with formulas, formats and conditional rules already wired | Not a template library in the same sense |
| Moving your existing work in | Use the add-on where the files already are, or import .xlsx and .csv | Import into their spreadsheet and work there |
| Learning curve | A spreadsheet and a chat box; nothing to configure | More surface: connectors, SQL editor, Python toolkit |
| A real grid with formulas and charts | Yes | Yes, with pivots and charts |
| Free tier | 10 credits on signup, no card | 50 credits a month, recurring |
| Python and SQL | Not offered | SQL editor and a Python data-science toolkit on paid plans |
| Very large files | Everyday spreadsheets; a browser grid has its limits | Files up to 10GB |
| Live data connectors | None. You import files or paste data | Connectors to databases, APIs and applications |
| Buying extra usage | Credit packs alongside a plan | Top-up credits at roughly two cents each, cheaper on the higher tier |

Both meter in credits, but a credit is not the same unit in each product, so do not divide one column by the other. What is comparable is the shape: their entry paid seat is $29 for 2,000 credits, ours is $20 for 1,000 with the Google Sheets add-on thrown in, and their free tier refreshes 50 credits every month where ours gives 10 once. Try both free before you decide - and if you are choosing for a team, price per seat, because that is where the two diverge fastest.
Choose Sourcetable if…
Their paid plans include a SQL editor and a Python toolkit. We have neither, deliberately - SheetAI is for people who work in spreadsheets, not notebooks. If you want both worlds in one window, that is a real advantage and it is theirs.
They advertise support for files up to 10GB. We are built for everyday spreadsheets, and a multi-gigabyte import is not a fair test of us.
Connectors to databases, APIs and applications are core to their product and absent from ours. If the spreadsheet is a front end for a warehouse, start with them.
Fifty credits every month, indefinitely, is more generous than ten credits once. If your usage is light and occasional, their free plan may cover you where ours will not.
Choose SheetAI if…
This is the one Sourcetable cannot answer. Our add-on brings twelve functions and the same chat into the sheets your team already shares, and it is included on every plan - no migration, no second place to look for the truth.
=AI_CLASSIFY written once and dragged down two thousand rows behaves like a spreadsheet: it recalculates, it lives in the file, and anyone who opens the sheet can see how the column was produced.
$20 a month against $29 a seat, and the add-on is included rather than being a thing they offer at all. For a small team the gap widens with every person you add.
Twenty templates - budget, invoice, CRM pipeline, timesheet, KPI dashboard, attendance register - arrive with formulas, number formats and conditional rules in place. Type over the sample rows and it calculates.
Connectors, SQL editors and Python toolkits are power, and they are also surface area to learn, configure and explain to whoever inherits the file. If what you actually need is a spreadsheet that does the boring parts for you, the simpler tool wins.
Moving across from Sourcetable
Sourcetable exports to standard spreadsheet formats, and our add-on may mean you do not need to move much at all.
- 1Sign in to SheetAI with any email address and use the ten free credits on a real task.
- 2Export a Sourcetable workbook to .xlsx and import it here; formulas and formatting come across.
- 3For work that is already in Google Sheets, install the add-on and leave the file where it is.
- 4Replace any Python or SQL step with a plain spreadsheet approach - or keep that specific workflow in Sourcetable, which is what it is good at.
- 5Run a full week of real work through ours before cancelling anything.
Be clear-eyed about the technical pieces. A workflow that leans on their SQL editor or Python toolkit has no equivalent here, and pretending otherwise would waste your afternoon. Those belong where they are.

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.
A cheap, tidy =AI function for Sheets and Excel. Good at filling columns; it is not a spreadsheet and it does not pretend to be.
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.
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.
