Sigma: Instant Analysis

Live selection math for Notion tables. See Sum, Average, Min, Max, and Count as you highlight cells.

Notion can total a column, but only the whole column, and only where a rollup has been set up. Sigma answers the smaller question you actually have in the moment: what do these particular cells add up to? HOW IT WORKS Select numeric cells in any Notion table. A small readout appears in the corner of the window showing the total and how many values you picked, and it updates as you change the selection. Click away and it disappears. You can move it to whichever corner suits you, or switch it off. Sigma reads the numbers as they are written. Values carrying a currency symbol or a percent sign are understood as numbers rather than skipped. PRO FEATURES • Average, minimum and maximum alongside the total • Results formatted to match what you selected, so currency stays currency, hours stay hours, and percentages stay percentages Pro is a one-time purchase. No subscription, no expiry, and it works on up to three devices. USE IT WHEN • Someone asks what a handful of line items comes to, mid-meeting • You are sanity-checking a budget before it goes out • You want a quick total without adding a rollup or exporting to a spreadsheet PRIVACY The numbers are read and added up in your browser. Nothing is transmitted, and we operate no server that could receive your data. Sigma is an independent extension and is not affiliated with, endorsed by, or sponsored by Notion Labs, Inc.
