Description
Drag, click or multi-select any numbers on a page to instantly see Sum, Count, Average, Median, Min and Max. **Summr** is a lightweight browser extension that turns any web page into an instant number calculator. Instead of copying values into a spreadsheet or handheld calculator, you simply drag or click to select numbers anywhere on the screen and immediately see live statistics: **Sum, Count, Average, Median, Minimum, and Maximum**. Built for productivity and accounting workflows, Summr intelligently recognizes international number formats—so whether your data uses commas, dots, apostrophes, or European decimal conventions, values like `7'200.00` or `1.230,95` are parsed correctly with zero configuration. **Key capabilities** - **Drag-to-sum** across tables, reports, and dashboards, or **click individual numbers** to toggle them on or off - **Multi-selection memory**: keep previous selections while adding new areas; re-select to remove values instantly - **Smart number-format detection** (US, European, and custom patterns) with optional filtering for numbers inside parentheses - **Six selectable stats**: Sum, Count, Average, Median, Min, Max—copy any result to the clipboard with one click - **13 color themes** and flexible keyboard triggers (Shift-click, Alt-click, etc.) - Optional **URL include/exclude lists** to control where the extension runs **Privacy by design** — all calculations happen locally in your browser. No page content, financial data, or statistics are transmitted to external servers. If you regularly review budgets, sales figures, tables, or pricing online, Summr eliminates manual adding and reduces copy-paste errors. Install it once and sum anything, anywhere.
