Free, because it never leaves
Drop a spreadsheet. Clean it, match the names, export the result. The computer in front of you does the work, so this part of RTIO does not have a price.
What you just paid for
Nothing left the tab.
A warehouse charges you to look at a file it had to receive. Here the file stays in the browser, and the price stays at zero.
01
Drop the file. Keep it.
The spreadsheet opens in the tab. It is not uploaded, and it is not copied into a folder that syncs away unless you export it.
02
Clean it where you already are.
Duplicates, gaps, new columns, filters, matches, joins, checks, and the download all run in DuckDB on this computer. Live APIs and cloud buckets still need the internet. Those nodes say Online.
03
The studio survives the airplane.
After the first visit, the dashboard still opens with the network off. The pipelines you save and the files you export live in a folder you choose. On Windows, that folder can start the same pages without signing in.
Safari may clear a stored file after a week away. Choosing a folder works in Chrome and Edge.
A model, if you bring one, only plans. It never reads the rows.
