Udemy Progress Percent

A lightweight Chrome extension (Manifest V3) that reads Udemy course progress (x / y) and displays it as a percentage.

Features

• Shows a small percentage badge in the header/progress area
• Adds an extra line inside the progress popover/tooltip (when visible)
• Works with Udemy’s SPA navigation (updates without full page reload)
• Avoids duplicate injection (updates existing elements)
• No external libraries (vanilla JS)

Install (Load unpacked)

1. Open chrome://extensions
2. Enable Developer mode
3. Click Load unpacked
4. Select the UdemyExtension/ folder

How it works

• Extracts progress counts using a language-agnostic number / number pattern
• Computes % = done/total * 100
• Uses a MutationObserver to react to dynamic DOM changes

Permissions & Privacy

• Runs only on https://www.udemy.com/*
• No data collection
• No network requests; everything runs locally in the browser

Known limitations

• Udemy UI/DOM changes may break selectors/detection logic
• If progress data is rendered late on some pages, the percentage may update with a delay
