Nothing to leak
Your files live in a folder on your disk. There's no cloud copy to be breached, subpoenaed, or quietly used for training. If your work involves salaries, patient records, or client financials, this is the whole argument.
Runs on your machine · No account · Works offline
The spreadsheet that
never phones home.
TableDI is a desktop workspace for real data work — connect, clean, calculate, chart. AI writes the formulas you'd rather not remember. Everything runs locally, so the numbers you're working on stay on your computer.
macOS (Apple Silicon & Intel) and Windows · Free version has no time limit
Your data doesn't go anywhere
Most "AI spreadsheet" tools are a website with your data sitting in someone else's database. TableDI is an application on your computer. That difference shows up in three places you'll actually notice.
Works with no internet
On a plane, on hotel wifi, behind a corporate firewall — it doesn't matter. The engine runs beside the interface on your own machine, so nothing waits on a round trip to a server.
No account to create
Download, open, start working. No email, no password, no team invite, no "verify your address" step. We don't have a user record for you, because there's nothing for it to point at.
From raw data to a chart you'd show someone
TableDI handles the whole path, so you're not exporting between three tools to answer one question.
AI writes the formula
Describe what you want in a sentence — "sum revenue by month, but only the paid invoices" — and get a working formula. The formula panel shows you what it produced, so you can read it, edit it, and learn from it rather than trusting a black box.
Big files stay responsive
The engine is built for volume, not for demos. Millions of rows scroll, filter, and recalculate without the spinning beachball you get when a spreadsheet hits its limit.
Link tables like a database
Relate sheets to each other and pull fields across them. It's the thing you were faking with nested VLOOKUPs, except it doesn't break when a column moves.
Pull data in from anywhere
Excel and CSV import with no row cap, plus connections to APIs and databases. Getting data in is never limited — that part is free, always.
Pivot and chart in place
Pivot tables, bar, line, and pie views built on the same data. Change the source, the dashboard follows. No copy-paste-into-slides ritual.
Automate the boring pass
The cleanup you do every Monday morning can run itself — scheduled workflows handle the repeat work while you look at the result.
Free for everyday use. Pay when you need the exits.
The free version isn't a trial and doesn't expire. What you pay for is getting data out — full exports, write-back, automation — plus the AI plugins.

Questions people actually ask
If it's offline, how does the AI work?
You bring your own API key from an AI provider, and TableDI calls it directly from your machine when you ask for a formula. That call carries your prompt — nothing else — and it only happens when you invoke it. We're never in the middle, and we never see your key or your data. Don't want any of it? Leave the key blank and the rest of the app works exactly the same.
Where are my files stored?
In a normal folder in your user directory — Application Support on
macOS, AppData on Windows. You can back it up, copy it to another
drive, or delete it. Nothing is hidden from you and nothing is held hostage.
What actually happens when I hit the free limit?
Exports stop at the first 1,000 rows of a sheet. Everything else — importing, calculating, linking tables, charting — is unlimited on the free version. There's also a full encrypted backup export on the free tier, so you can always take all of your data with you, even if you never pay us.
Is the lifetime license really one payment?
Yes, including future updates. We'd rather sell you the software once than bill you forever for the same thing.
Can I use it on more than one computer?
A license activates one machine at a time. You can release it from inside the app and activate somewhere else whenever you like — so switching laptops is fine. For two machines running at once, you'd need two licenses.
Does my team get a shared workspace?
Not in this product. TableDI here is a single-user desktop application by design — that's what makes the local-first guarantee possible. Collaboration means a server holding your data, which is the thing we're deliberately not doing.
Try it on your messiest file
That's the honest test. Download it, throw your worst spreadsheet at it, and see what happens. Free, no account, nothing to cancel.
